I put H3 buffers in my guns and now c products and asc mags work fine with steel ak ammo. a slower BCG with a lot of wt behind it gives the mag follower and spring time to lift up the round.
I have only used unaltered C Products Defense (CPD) magazines and they all have been flawless. I have four 10 round and two 30 round CPD magazines. C Products is another company the predates CPD. From what I researched, stay away from all C Products magazines. Also, my recipe for making my 7.62x39 AR work without issue is using an "enhanced" firing pin, a Wolff Gunsprings extra power buffer spring with a carbine weight buffer, and a Sprinco (Tactical Springs) extra power 5 coil extractor spring with only an insert and no CRANE style o-ring. Since using these parts and CPD magazines, I have not experienced one FTFire, FTFeed, or FTE. I hope this info helps anyone experiencing problems.
The extra power buffer spring would be a key factor if somebody doesn't intend to modify the 30 rnd magazines. I'm sure your recipe for success will help people. I had to modify my firing pin to "enhance" it, Radical just sent me a normal FP with my BCG and upper.
Joseph, my man! thanks for the love and for really knowing our story. Please follow us on all our social platforms for great content and tons of new products this year
i had similar issue & spring from wolf fixed the issue. i know u dont wanna spend any more cash on them, & my 10 & 20 rounders have always worked fine, only 30rnders gave issue, thanks for the video. its appreciated.
Thanks for this video. I've had the same dang problem with 10-round mags from C-Products vs. ASC. ( We can't get 30s shipped here to Colorado ). The ASC mags had nothing but failures on the last range trip, and I thought it was the BCG. After watching this, it's pretty clear. I'll have to get my Dremel out and apply your suggestions. Unfortunate that we have to do this, but as shown in the first part of your video, the accuracy is great with this type of rig... so it's worth it. Much appreciated.
It's more accurate than I expected and worth the trouble. One thing guys are doing to overcome the force needed to strip the rounds out of the magazine is use a extra power buffer spring.
You're welcome. I'm not entirely happy with the C-products mags either though. There are videos where you can take a nibbler and modify them. Also, out of 5 mags I had 1 that wouldn't drop free and one that barely fit in the receiver. If you have that problem, send them back they are warrantied.
For a 7.62x39 and a pistol version you need these modifications !! Buy a Geissele twisted wire recoil spring with an H2 buffer. Next, buy a extra power hammer spring to be more reliable on igniting Russian ammo primmers. Next, make sure on your m-4 feed ramps that you have the larger .30 caliber sized feed ramps instead of the standard .556/.223 feed ramps. If you don't make sure your feed ramps are right your weapon won't be reliable enough to protect your love ones if necessary. Next, check that your firing pin will protrude thru the bolt enough for reliable primer strikes. You might have to get a enhanced firing pin that is a little longer. I hope this helps.
thanks for the video, I had the exact same opinion on these 2 magazines, the 30 round ASC magazines have been nothing but trouble, I got my hands on the new cproducts mags which just look and feel like a complete different league, I also noted the cproducts are nicely machined without all the sharp edges and the follower is buttery smooth vs the ASC mags that just look like they are half done.
Thank you so much for the love and the well thought out inspection and review! Please keep in touch as we can never get enough feedback, especially if there is an issue.
Come on. I've got no dog on your mag right but this is not a video showing mag performance. If you want a rifle that says one mag, a few ammo choices and it might work then cool. But before you review the mags I would fix my gun. Show me the difference on a weapon that's properly built. Then show me the benefits of one mag over the other.
I went with ASC 20rnd mags, but in my carbine. I noticed before I ever shot it that the mags would scrap the rounds. used some 400grit to smooth and polish the lips. One thing I saw when you shot, is just how much more recoil your gun made. with a rifle, your shoulder bears the recoil, but the way you are shooting is somewhat equivalent to limp wristing an auto pistol. the more the gun free recoils, the more prone it is to not cycle a round. thanx for the tips.
I think you may be right, but with a new C-products mag. ( I've tweaked 4 more) it takes around 6 lbs or force for the bolt to push the round out. (check it with trigger pull gage) Tweaking the mag can cut that down to 3 lbs. There are so many videos of guys using nibbler pliers I'm not gonna make one.
@@ginsboy2003 Not "nibbler pliers", but 'hose clamp pliers'. Not as sharp nor needed to be as Kurt Eschman only uses them to bend down or flatten the metal protrusions inside the magazine's feed lips.
I'd like to try some 20 rounds mags. after tweaking the ASC mags they now work better than the C-products. I've tweaked the C-products mags a little more and am actually heading to the range today.
Great video. I have the same problem with ASC mags. Will fill down the sides and go from there should have bought c products instead. My mags are 10 round. Didn't pay much for them. Thanks for the info.
I haven't tried them yet however the 20round mags work great. I believe the problem is with the dog leg in the 30s and the follower. That coupled with the spring. I sanded the follower, trimmed the lip at the top and actually stretched out the spring so far. They seem to feed a lot better. Manually at least.
I'd bet $100 they put the same spring from their 20 rounders in the 30 rounders thats why I had so many failures where the rounds didn't move up fast enough.
yeah I ended up adding wolf springs to my ASC 30's, the springs that come with them are a joke like your found, over all they seem to be made as cheaply as possible cutting every possible corner. cproducts has had a number of issues and revisions but their latest revision is brilliant
Had this happen with my 3 d&h 556 mags from bcm the front of the mag would hit on the edge of the bullet like yours basically impossible to get out had to file it down a bit and lightly sand the feed lips because it was a bit rough seems fine now haven’t shot them yet do to ammo shortage still a bit rough but I’ll just run them a bit till they smooth out my 1 magpul magazine I have the front of the mag wall was much lower so no problem snagging the bullet and is silky smooth to feed I still don’t regret my purchase of the d&h mags
I had the same issues with the ASC Mags. and did the same modifications that you performed but I also bent the feed lips on the ASC mags up a few millimeters in the front so as to tilt the nose of the bullets up so they feed smoother. Now my ASC mags are more reliable that the C-Products and have been for a couple years now. I do urge people to do some heavy research before building a 7.62 AR because to get the rifle to 100% reliability takes a whole host of modifications and tuning techniques. Especially if you are planning on running the inexpensive & Very affordable steal case Russian ammo. The 2 biggest issues I have found with the AR ( 7.62 x 39 ) is that the gas ports on the barrels are WAY too small leaving the system considerably under gassed. Drill out the gas port to a very large ( .125" ) and get an adjustable gas block for perfect tuning. Then modify the feed ramps by grinding away the dual Fork style of the AR and " Dishing " out the feed ramp to a single ramp like the AK. Only Bushmaster did this with their AR ( 7.62 ) and they famously had the most reliable ( 7.62 ) AR's on the planet. Google " Bushmaster 7.62 x 39 AR-15 Feed Ramp " and you will see what I mean. Combine all of this with ( Wolf Extra strength hammer springs) , ( Extended firing pin ) , ( Superior Shooting Systems - Flat Wire buffer Spring ), ( Extra Strength extractor spring kit ) and the final addition that will get you to the 100% reliability plateau that everyone wants to be at with any rifle is the ... POF ( Patriot Ordinance Factory ) " E2 dual extraction system " which is a chamber pressure modification system that they will perform on your existing barrel. It uses the spent gas to slightly dislodge the spent case before it is extracted making the normal tight and messy extraction process silky smooth. Now this costs ( $150 ) and takes a few weeks and should be done only after the other modifications i list but it will take your rifle to the Amazing stage ! But, if you just do what I have listed above and skip the E2 system you still will have a Very reliable rifle but the E2 will go longer , well into the crazy dirty chamber stage and still allow the case to be extracted. So the difference is how many rounds you can shoot before the chamber gets just SO damn dirty that the case sticks just enough to cause a failure. With all of the modifications including to the magazines I usually get around ( 750 - 850 ) rounds of the Nasty dirty Russian Bear steel ammo before I get a failure and have to clean the chamber real quick. but with the E2 system i get up to ( 1,000 - 1,100 ) before i get a sticking issue. You can obviously run that round count up by using a higher quality & cleaner brass ammo and / or a Piston system that will keep the chamber much much cleaner. Then you can go a long way without an issue but it depends on where you want to be for the price. Good Luck
I was able to shot the ASC mags if I didn't store the ammo in the mag, but when I kept a loaded ASC mag for a number of months the mag wouldn't feed the ammo right. I did the same thing with the C Products mag (I stored it loaded even longer than the ASC mag) and it worked 100% with no issues. Based on that experience I won't buy ASC mags even for 5.56/223.
I had the same follower issue with my ASC magazine, and all I did to remedy it was to spray some lube in there. Its like butter now. Work smarter not harder.
Dry or wet lube hasn't worked on the last 3 ASC mags that I have dealt with, cutting a couple of spring windings to lighten up mag follower tension did though. Some ASC mags are so out of spec they won't even feed into the magwell of some lowers...!
One of the possible solutions to reduce or eliminate the nose dive is to remove about one inch of material from the front part of the mag (the front wall, where the tip of the rounds drag), I know that removing one inch of material sounds excessive, but if the two top rounds don't have a mag wall in front of them to rub against, then they can't hang up on it. I have done it to mine and it works, of course that's a lot of grinding, so use your ingenuity and do it however you think is best for you, if you do it at all.
C-products fan boy video. Flat spring versus a standard spring, had to Dremel both so... I'm kinda thinking your mind was made up before the production began.
I have built 3 of these rifles and all seemed to have the magazine issue but wasn't the magazine I had to Dremel the upper receiver at the M4 ramps each time fixed my rifles
i had the same issues with the c products.. put priority ak 47 + 5 up springs in and took a dremel to the 2 rear notches and flattened them out and polished them ... no more issues with any ammo...
I believe one of the main problems of these mags, especially the ASC, is the finish paint, that’s why the follower feels so rough and makes squeaky sounds when pushed down manually. If they left the metal bare on the inner walls, or better yet, placed the mag casing in polishing tumblers to polish the inside walls and paint only the outer walls, the mags would run much better, like AK47 mags. I’ve greased the inner walls of ASC mags and the follower moved 5 times better up and down, but I think a better solution would be to use a polishing wheel and polish smooth the inner walls especially towards the top side of the mag, the inside of the feeding lips, and the high points of the ridges, that will allow the steel cartridges to slide much better into position and out of the mag feeding lips. All that extra work that manufactures should have done in a polishing tumbler, so easily.
Excellent vid. I bought an AR Stoner mag to test my build. What a nightmare. C Products Duramag allowed me to focus on fixing the gas problem. Has anyone else had to open up a 556 spec gas port on 7.62x39?
Yeah my 10.5 inch barrel I had to open the gas port. Was short stroking with a light weight buffer and spring. This was the very last result after I ruled out the mags, bcg. Once I did that I was able to put the regular carbine spring back in the gun and a H-1 buffer. Now it runs flawless and the recoil impulse is nice.
I dont want to be critical here, just an observation. In the beginning when he removed the spring in the ASC mag the tallest portion of the spring was oriented to the rear of the body of the magazine and follower. Then after the mods and the follow up range trip he said the rounds were nose diving and therefore wouldnt chamber. At the range he stated the tallest portion of the spring went to the front of the follower. I wonder if this was the reason one ASC mag worked and the other didnt. I agree my ASC mags needed some minor mods to the body to function properly too. I happen to like your videos and in depth approach to builds. Keep up the good work
The position of the mag spring definitely makes a big difference in the ASC mags, that’s one of the tests I performed while trying to find what was wrong with them.
Did u ever find a 'fix' for the springs the ASC? I just emailed ASC about all the issues I'm having with their mags. At this point I wish they would just send me 3 springs for 30 rd mags and I would cut them to work with my 20s. Longer than the ones currently in it
Ginsboy2003 Thank you for the video a the tips, however I have one critical question, in the comments below you say that you finally got the ASC mags to work even better than the C Products mags, could you please share what else you did to make them more reliable? Thanks.
@@battleborn2002 I know, not only ammo and guns but mags too are hard to find. Subscribe for notifications on every website like Classic Firearms and move quickly to get it.
I just sent back 20 30rd, and 2 20rd ASC's. I am having the same problems you were having. Same crap. Scrapes on the casings, bolt passing over the round. Jamming at the front of the mags. I also have a hard time seating the mags when the bolt is closed. My combo is the Palmetto Upper and lower. I tried seating the mags using my brother's Windham lower. Same problems. If you compare them to a D&H or C products 5.56 mag they look the same.
I meant regular 5.56 AR15 mags from D&H. PSA was running mondo deals on them for a whole. Like $6.99+ free shipping if you got 10 or more. Haven't seen that in a while.
perhaps the kinked up portion of the spring on the asc magazine is meant to go to the front to push up the nose of follower? I also notice the retaining/feed lips on the asc magazine are a little bit longer than on the c products magazine which may make for a less ideal feed angle...
Could be that part should go to the front. I was pretty surprised to see the ASC spring about 4-5 inches shorter also. When I removed the material that was cutting into the sides of the cases, it did move the mag lips back slightly, maybe tweaking them upward slightly or moving them back more would help.
In 1911 guns, the front part of the mag lips are slightly bent up to allow the cartridge’s nose to rise slightly and begin aligning with the barrel’s chamber, so maybe bending just a bit the front of the mag lips of the ASC mags, will help the cartridge feed better and avoid getting caught on the front edge of the mag bring that the nose of the cartridge will be just a bit higher when it reaches that point. Also in regards to the ASC mag spring, flatten the kinked top loop of the mag spring, make it look identical to all AK mag springs and the C Products mag spring, and also install it like all AK springs, with the end of the spring pointing to the rear of the mag, try installing it both ways and you’ll see that one way makes the mag feed much better than the other.
Great video, but not enough there was enough info on the rifle/pistol. If that is a pistol length gas system with mil-spec buffer set up, I would say over gassed and needs a stiffer spring as someone else suggested and/or a heavier buffer. Also, C-Mags need a good slap to properly seat. Once I learned that, Ive had many rounds trouble free on numerous builds with C-Mags. .
very very impressive accuracy. spend the $$$ on the marine corps ar-47 special ops mag, yeah the yellow interior is getting replaced with a rocket red.
I could easily see what needed dremeled on the ASC mags so I tweak the feed lips. The C-products mags usually need tweaked as well but don't have half the problems of the ASC mags.
Thanks. I'm a little pissed at myself for buying two ASC 10/30 rounds mag at $30 each. I have five 10 round Duramags that never gave me any issues. I just needed magazine length so I took the chances on the ASC, even though I was aware of their bad reviews. 😔 Thanks for the video, I really appreciate it. You got a new subscriber. Btw any updates on those ASC mags?
get a strike industries long flat recoil spring and right under the feed lips smooth or dremell those damn reinforcing dimples under the feed lips to be smooth that way the rim wont snag on the 2 reinforcing dimples on each side
Hi, you should probably try the c-products 28 round 7.62x39 magazine,. it's in a completely different class being the same size as as the USGI 5.56 mag and more reliable. Thanks
@ 16:00 you show the front of the follower. I would take 1/8 " off the bottom of the "leg" and smooth the cut, try it again. Mr Guns n Gear had great success doing this with an AK74 mag, look up the video. One other thing I'm not hearing about is Wolff xtra power magazine springs, which would be the first place I'd go after fixing the follower. OK, long vid and you did the spring!
I have C-products grendal. I had this problem for first 40 rounds.. Then it worked flawless for next 200 rounds. Not it is doing this again. Usually bolt goes over round.
How in the hell can you talk about magazines for 42 minutes that's the only reason I didn't finish watching it you answered my question in the beginning C mags are the way to go
For the Love of REASON!! I wondered the same thing about 10 seconds into the video. He says every thing I wanted to know in the first 37 seconds. C Products works great, ASC still won't work reliably, thanks moving on now. Doing research for my first 7.62 x 39 AR Build.
I finally took those mags back to the range. the 30s still aren't working after mods. I think it does need better springs. I purchased a D&H from brownelles. they were the only ones that had them in stock. They're a little pricey $20. When I try them I will let you know
ginsboy2003 the new D&H mags had one failure to feed. the bullets will nose dive in mags so I sanded the front of the follower and it's a hundred percent now. They work much better than the ASC mags do out of the box.
I wonder if some of the problems noted are due to the pistol configuration. I know that pistol AR are problematic even in 5.56, so I would like to see this same test done with a rifle configuration. I have an ASC 7.62x39 magazine and it has worked without any problems from day one. Anderson lower with PSA upper (using the enhanced firing pin). I'm going to try a C Product also to see if I notice any differences.
The C-products mags still needed a little tweaking. Using an AK mag spring in an ASC magazine seems to be a common fix on the 7.62x39 forums when your rounds aren't coming up fast enough to be picked up by the bolt. With the mags I had, doesn't matter whether you had a pistol or rifle, the metal still needed to be removed so they would work.
I'm working on my 3rd .300 BLK PDW (pistol W brace) and the first two are running 100%. Use the right parts and you'll be fine. One thing I'm not hearing about is Wolff xtra power *magazine* springs, which would be the first place I'd go after fixing the follower
I've been in injection molding for over 20 years. It looks like your problem with the ASC follower is due to mold damage. It looks like whoever does the molding for C-Products takes better care of their molds. You can tell by the smoother surface and the lack of a parting line flash that you find on the ASC follower. If you ask me, ASC is using an older mold to produce their follower.
John, appreciate the attention to detail. We take immense pride in our manufacturing and a very picky with our process. this mag in particular is a real point of pride for us. The geometry, the follower, Spring design, and the materials in all our magazines are designed with zero compromise.
C Products Defense I sent some CPD mags back to be replaced because the anti tilt follower on some of the magazines was not working. It has been a month since I have heard anything.
Good luck finding the C-products mags... Also, you need to be careful with the follower, if it gets too small, it with potentially catch the side of the mag at more of an angle because of the expanded space. So just polish them lightly and knife off the burs, don't sand them down completely. Does that gun have an M4 feed ramp?
I think the issue of the bullet hanging up on the front lip maybe be negated by the bullet being guided upwards by the barrel ramp before it exits the magazine. I would like to see how the bullet travels out of the magazine when installed in the firearm. The other areas on the sides of the mag lips is probably the important issue to deal with. Do you seat your bullets to back of the mag after you load them? how are the mags working now? That was some great groups on the target, what distance were you shooting? What optic were you using?
I seat the bullets to the back of the magazine. The mags work great now after tweaking. I've also learned some people overcome the magazine problems with an extra power buffer spring. I really don't think that is fixing the problem but as long as it works for them. The first optic we put on was a cheap NCstar holo sight. Now I have a Vortex sight on it. My son shoots better with this than he does his AR at short ranges.
ginsboy2003, very good video. when i called R.F.'S they said to use ASC Mag.'s i bought 2 - 16" complete x39 uppers for $199.00 each. so i had worries but they worked but had same issue with the 10 mags ASC i bought from "44mag.com" but i studied them and came up to same that you did. lol. now i have 2 complete 30 cal. carbines for apox. $550.00 each. But since after buying the ASC Mag i bought 10 C Mags and had issues with them out of the box too. But once i did what you did they both work very well now. just wish Magpul would make some x39 mag.'s but after emailing them they said "magpul at this time has no plans making them". So we have to just tweak either mag's till we can get better ones. no big thing. thanks, BTW, nice to shoot .30cal. for .22 cents a round.
I can't understand why'd they'd recommend ASC. When I asked a buddy at work about the two mags, he just said to go with C-Products since they make the mags. for the US military. Didn't research to see if they do or not, but the steel in them is definitely harder than in the ASC mags and quality control is a lot better!
agreed, but i emailed R.F.'s several times about this issue. i didn't want any problems with x39 build then one of their techs gave me a phone number to call. i called him asked how can they sell uppers so cheap, and if their uppers were reliable? he said they buy close outs from all over the place, they open gas port little bit on x39's, give an enhanced firing pin too. then what mag.'s should i get he said ASC mags so i made sure i got them and had same issue as yours but i also figured out same to make them work. i stripped the mag and filed, stoned, front n sides to a mirror finish and all is good. but i have 10, 20, 30 rd's now and in the 30 rder's my spring looks longer than on yours. maybe they changed the springs ? any way good luck with your pistol now hope all is good. BTW, Do you have a video on repairing milsurp wood stocks? like cracks, finishing, bringing them back to good service again? be safe n thanks.
MegaBait56 I'm going to look at my firing pin and compare it to another. I have some Russian ammo I bought 10 years ago that will not fire no matter how many time I rechamber and pull the trigger. Maybe I need an extra power hammer spring. These dang ASC mags shouldn't be kits we have to spend so much time on. I do have a video on the repairs I did on my Nepal Gahendra stock where I removed some rot and filled a crack. It might give you some ideas. In this video I only describe the work but you will get the idea. ua-cam.com/video/0g-Kj2MpGto/v-deo.html
thanks will check it out. if you bought R.F.' bcg you will see it. called "enhanced firing pin" you can even goggle it . they also said for hard primer Russian ammo to use a Wolff hammer spring. forgot to tell ya before.
Sorry for the criticism. Started watching to get info but i became distracted by improper gun safety. Turn the safety on once in a while. Like when you are done shooting or notice a problem. Thats what its for. SAFETY
Those are great groups. You've got 5/8 of an epic gun. Either lesson the gas (which could result in a fail to cycle) or get a heavier buffer (spring or buffer weight) your mags arent your issue.
Hey Vet. I'm confused by your comment you say to lessen the gas or use a heavier buffer and spring right? If he was to use a heavier buffer with the bolt doing what its doing would make matters worse because he doesn't have enough gas pressure as is.
I had the same problem with ASC mags for my Windham AR 7.62x39. I received ASC mags for my Windham 5.56 so I assumed they were using the same company for the 7.62x39. You know what they say about 'assume'... WRONG! They were using D&H mags for their AR 7.62x39 and they have worked FLAWLESSLY.
Is there a stiffer spring available for the bolt buffer? This would seem more logical to change instead of modifying all the mags. In a SHTF situation one does not have time to tweak magazines especially if you find a stache in the field someone had concealed.
In a SHTF situation you're probably not going to find 7.62x39 AR mags unless they are yours. Still just not that common. Stiffer spring may cause failures to feed as well unless you enlarge the gas port.
That awkward moment when you just bought 2 FDE 7.62x39 ASC mags for your brand new AR build and then watched this video!!! GD IT! :/ We shall hope and see now. So, Ive had this issue before with an AR10 ASC mag i bought from Midway, it was labeled AR Stoner on their site and its most definetly not Stoner as the mag has ASC on the floor plate and follower. However, i was able to fix the .308 mag by polishing the lips and follower, and dremeling down the tab at the front of the mag, where the neck of the case would catch on the body. Cycles fine now but your left with that feeling of not being 100% reliable. Its obvious that the people in the cleanup department at ASC are permanently out to lunch, the burrs left on that .308 mag were freakin dangerous and they made me laugh out loud. Come on people @ ASC, do your job!! If these 2 new FDE 30 rounders are like the AR10 mag ill be pissed, but ill know at least how to fix them. Glad I have a legit AR Stoner 10 round in case these ASC are bad. Thanks for the video!
These magazines are very poorly made, and extremely unpolished. The lip of casing seal shouldnt be getting hung up on metal as it leaves. This is just simply unsafe.
No need to install a stronger buffer spring or heavier buffer weight just need a better mag. Some ASC mags are so out of spec they won't even feed into the lower magwell without modification...!
I planned on addressing it also, but the case mouth was also hitting hard. A slight ramp fixed that. I'm take care of the dimples as so many other people suggested just to make them more reliable.
It’s absolutely the ASC mags fault. I have 2 20 rounders and they are so rough in function. I haven’t even built my AR yet and I know they won’t work. The followers tilt like no tomorrow . The springs have sharp edges binding on all interior indentations. Rounds tilt and dip when loading. I’m sorry I bought them. Absolute crap.
C-Product mags for 7.62x39 are the only way to go . ASC mags are paperweights and after the purchase the company doesn't care about you they don't return emails if you have a issue that might cost them money . I mean they're fine for the range if you only put a few bullets in at a time .. maybe the C stands for California compliant? ASC overpriced and they don't work. Save some $ and stress go with C products I mean you can go to the ASC UA-cam page where they review their own 7.62x39 magazines and the comments are TURNED OFF that should tell you something right there
ASC mags are trash. I ordered 10 and they all came with spread feed lips and rounds would just fly out once I loaded about 6+. I had to crush all the feed lips back together. After using these mags for some time, I noticed the front lip of the mag was flaring our from the rounds being smashed into the wall of the mag(7:10). These mags are just simply trash imo.
There stainless steels work perfect! They use a magpul style anti tilt follower. The aluminum which i didnt watch full way but bet u have there have the old style mil-spec followers that are junk!
You said "look at how much more tension the C Products spring has than the ASC spring has". But all we can see is the different 'length'. We cannot 'SEE' 'tension'. 'Tension' must be felt. Just because one spring is longer doesn't mean it also has more tension. It may, but it also may not.
You're limp wristing causing the bolt to not have enough inertia to follow through (like a 12ga semi auto shotgun). The lack of a brace is one thing; i would also get a heavier buffer and spring.
Bad mags a lot of ASC mags are so out of spec they won't even fit into the lower magwell without modification, the last 3 mags I have dealt with had to have several windings cut out of the spring due to excessive follower tension...!
I dont like your gun safety at the range. You are pulling the trigger several times while not looking down the sights or braced for the shot. This is an accident waiting to happen, especially with an unreliable weapon.
Thanks for your time making this video. Liked and subscribe to you. 👍👍👍
I put H3 buffers in my guns and now c products and asc mags work fine with steel ak ammo. a slower BCG with a lot of wt behind it gives the mag follower and spring time to lift up the round.
Great video as always. Thanks for helping others save a lot of money and time.
I have only used unaltered C Products Defense (CPD) magazines and they all have been flawless. I have four 10 round and two 30 round CPD magazines. C Products is another company the predates CPD. From what I researched, stay away from all C Products magazines. Also, my recipe for making my 7.62x39 AR work without issue is using an "enhanced" firing pin, a Wolff Gunsprings extra power buffer spring with a carbine weight buffer, and a Sprinco (Tactical Springs) extra power 5 coil extractor spring with only an insert and no CRANE style o-ring. Since using these parts and CPD magazines, I have not experienced one FTFire, FTFeed, or FTE. I hope this info helps anyone experiencing problems.
The extra power buffer spring would be a key factor if somebody doesn't intend to modify the 30 rnd magazines. I'm sure your recipe for success will help people. I had to modify my firing pin to "enhance" it, Radical just sent me a normal FP with my BCG and upper.
Joseph, my man! thanks for the love and for really knowing our story. Please follow us on all our social platforms for great content and tons of new products this year
I think the spring might have been installed backwards on the assembly process.
i had similar issue & spring from wolf fixed the issue. i know u dont wanna spend any more cash on them, & my 10 & 20 rounders have always worked fine, only 30rnders gave issue, thanks for the video. its appreciated.
Thanks for this video. I've had the same dang problem with 10-round mags from C-Products vs. ASC. ( We can't get 30s shipped here to Colorado ). The ASC mags had nothing but failures on the last range trip, and I thought it was the BCG. After watching this, it's pretty clear. I'll have to get my Dremel out and apply your suggestions. Unfortunate that we have to do this, but as shown in the first part of your video, the accuracy is great with this type of rig... so it's worth it. Much appreciated.
It's more accurate than I expected and worth the trouble. One thing guys are doing to overcome the force needed to strip the rounds out of the magazine is use a extra power buffer spring.
Very informative video. I saw some guy was also using an AK spring in the AR mag along with grinding the front and rear of the mag.
great video! That's a real solid review. Helped me . Thanks
You're welcome. I'm not entirely happy with the C-products mags either though. There are videos where you can take a nibbler and modify them. Also, out of 5 mags I had 1 that wouldn't drop free and one that barely fit in the receiver. If you have that problem, send them back they are warrantied.
Excellent video. Thank you very much.
For a 7.62x39 and a pistol version you need these modifications !! Buy a Geissele twisted wire recoil spring with an H2 buffer. Next, buy a extra power hammer spring to be more reliable on igniting Russian ammo primmers. Next, make sure on your m-4 feed ramps that you have the larger .30 caliber sized feed ramps instead of the standard .556/.223 feed ramps. If you don't make sure your feed ramps are right your weapon won't be reliable enough to protect your love ones if necessary. Next, check that your firing pin will protrude thru the bolt enough for reliable primer strikes. You might have to get a enhanced firing pin that is a little longer. I hope this helps.
This right here! 👍🤙👌 well said Chris!
thanks for the video, I had the exact same opinion on these 2 magazines, the 30 round ASC magazines have been nothing but trouble, I got my hands on the new cproducts mags which just look and feel like a complete different league, I also noted the cproducts are nicely machined without all the sharp edges and the follower is buttery smooth vs the ASC mags that just look like they are half done.
The C-products still need work, but they are better than ASC mags.
Thank you so much for the love and the well thought out inspection and review! Please keep in touch as we can never get enough feedback, especially if there is an issue.
Just bought two of your magazines to replace my ASCs
Come on. I've got no dog on your mag right but this is not a video showing mag performance. If you want a rifle that says one mag, a few ammo choices and it might work then cool. But before you review the mags I would fix my gun. Show me the difference on a weapon that's properly built. Then show me the benefits of one mag over the other.
I went with ASC 20rnd mags, but in my carbine. I noticed before I ever shot it that the mags would scrap the rounds. used some 400grit to smooth and polish the lips. One thing I saw when you shot, is just how much more recoil your gun made. with a rifle, your shoulder bears the recoil, but the way you are shooting is somewhat equivalent to limp wristing an auto pistol. the more the gun free recoils, the more prone it is to not cycle a round. thanx for the tips.
I think you may be right, but with a new C-products mag. ( I've tweaked 4 more) it takes around 6 lbs or force for the bolt to push the round out. (check it with trigger pull gage) Tweaking the mag can cut that down to 3 lbs. There are so many videos of guys using nibbler pliers I'm not gonna make one.
I said the same thing
@@ginsboy2003 Not "nibbler pliers", but 'hose clamp pliers'. Not as sharp nor needed to be as Kurt Eschman only uses them to bend down or flatten the metal protrusions inside the magazine's feed lips.
I have a 16 inch kit that a built. I only bought 20 round mags from asc they have been perfect so far 200 rounds thanks for the vids.
I'd like to try some 20 rounds mags. after tweaking the ASC mags they now work better than the C-products. I've tweaked the C-products mags a little more and am actually heading to the range today.
The parts u colored in black u can just bend those back slightly and it tilts the bullet up feeding flawlessly
Great video. I have the same problem with ASC mags. Will fill down the sides and go from there should have bought c products instead. My mags are 10 round. Didn't pay much for them. Thanks for the info.
Great video. Exactly what I needed to see. I'm having the same problem with the ASC 30 round mags
If you can get your ASC mags working better, let us know.
I haven't tried them yet however the 20round mags work great. I believe the problem is with the dog leg in the 30s and the follower. That coupled with the spring. I sanded the follower, trimmed the lip at the top and actually stretched out the spring so far. They seem to feed a lot better. Manually at least.
I'd bet $100 they put the same spring from their 20 rounders in the 30 rounders thats why I had so many failures where the rounds didn't move up fast enough.
ginsboy2003 I haven't pulled a 20 apart. When I do I will let you know
yeah I ended up adding wolf springs to my ASC 30's, the springs that come with them are a joke like your found, over all they seem to be made as cheaply as possible cutting every possible corner. cproducts has had a number of issues and revisions but their latest revision is brilliant
awesome info...noticed a year ago the ASC were more plentiful and cheaper than the c products (in all calibers)...
Had this happen with my 3 d&h 556 mags from bcm the front of the mag would hit on the edge of the bullet like yours basically impossible to get out had to file it down a bit and lightly sand the feed lips because it was a bit rough seems fine now haven’t shot them yet do to ammo shortage still a bit rough but I’ll just run them a bit till they smooth out my 1 magpul magazine I have the front of the mag wall was much lower so no problem snagging the bullet and is silky smooth to feed I still don’t regret my purchase of the d&h mags
ginsboy is the man. watch his ak builds. After doing all this myself I realized I built and sks
thanks for this info building one for myself now i will be ordering cproducts in 20 and 10 round for bench shooting
Your initial results were the same for my AKR pistol build. I decided to go full on with C-Products Defense mags and not bother with ASC.
I had the same issues with the ASC Mags. and did the same modifications that you performed but I also bent the feed lips on the ASC mags up a few millimeters in the front so as to tilt the nose of the bullets up so they feed smoother. Now my ASC mags are more reliable that the C-Products and have been for a couple years now.
I do urge people to do some heavy research before building a 7.62 AR because to get the rifle to 100% reliability takes a whole host of modifications and tuning techniques. Especially if you are planning on running the inexpensive & Very affordable steal case Russian ammo.
The 2 biggest issues I have found with the AR ( 7.62 x 39 ) is that the gas ports on the barrels are WAY too small leaving the system considerably under gassed. Drill out the gas port to a very large ( .125" ) and get an adjustable gas block for perfect tuning. Then modify the feed ramps by grinding away the dual Fork style of the AR and " Dishing " out the feed ramp to a single ramp like the AK. Only Bushmaster did this with their AR ( 7.62 ) and they famously had the most reliable ( 7.62 ) AR's on the planet. Google " Bushmaster 7.62 x 39 AR-15 Feed Ramp " and you will see what I mean. Combine all of this with ( Wolf Extra strength hammer springs) , ( Extended firing pin ) , ( Superior Shooting Systems - Flat Wire buffer Spring ), ( Extra Strength extractor spring kit ) and the final addition that will get you to the 100% reliability plateau that everyone wants to be at with any rifle is the ... POF ( Patriot Ordinance Factory ) " E2 dual extraction system " which is a chamber pressure modification system that they will perform on your existing barrel. It uses the spent gas to slightly dislodge the spent case before it is extracted making the normal tight and messy extraction process silky smooth. Now this costs ( $150 ) and takes a few weeks and should be done only after the other modifications i list but it will take your rifle to the Amazing stage ! But, if you just do what I have listed above and skip the E2 system you still will have a Very reliable rifle but the E2 will go longer , well into the crazy dirty chamber stage and still allow the case to be extracted. So the difference is how many rounds you can shoot before the chamber gets just SO damn dirty that the case sticks just enough to cause a failure. With all of the modifications including to the magazines I usually get around ( 750 - 850 ) rounds of the Nasty dirty Russian Bear steel ammo before I get a failure and have to clean the chamber real quick. but with the E2 system i get up to ( 1,000 - 1,100 ) before i get a sticking issue.
You can obviously run that round count up by using a higher quality & cleaner brass ammo and / or a Piston system that will keep the chamber much much cleaner. Then you can go a long way without an issue but it depends on where you want to be for the price.
Good Luck
Mark Mitch ^ this ... ive also done it on pistols ..will eat anything after that mod
I was able to shot the ASC mags if I didn't store the ammo in the mag, but when I kept a loaded ASC mag for a number of months the mag wouldn't feed the ammo right. I did the same thing with the C Products mag (I stored it loaded even longer than the ASC mag) and it worked 100% with no issues. Based on that experience I won't buy ASC mags even for 5.56/223.
I had the same follower issue with my ASC magazine, and all I did to remedy it was to spray some lube in there. Its like butter now. Work smarter not harder.
Dry or wet lube hasn't worked on the last 3 ASC mags that I have dealt with, cutting a couple of spring windings to lighten up mag follower tension did though. Some ASC mags are so out of spec they won't even feed into the magwell of some lowers...!
PSA lowers are too tight for 7.62x39 mags, but Anderson lowers are good to go.
@Frank Andrew The fix for ACS mags is to replace them with C Products Defense (AKA Duramag).
You successfully took suspect mags and made them total chit
On your second range trip you seem to have had the asc spring bacwards.
It does make a difference if the mag spring is backwards, at least in the ASC mags in 7.62x39 it makes a big difference
One of the possible solutions to reduce or eliminate the nose dive is to remove about one inch of material from the front part of the mag (the front wall, where the tip of the rounds drag), I know that removing one inch of material sounds excessive, but if the two top rounds don't have a mag wall in front of them to rub against, then they can't hang up on it. I have done it to mine and it works, of course that's a lot of grinding, so use your ingenuity and do it however you think is best for you, if you do it at all.
C-products fan boy video.
Flat spring versus a standard spring, had to Dremel both so...
I'm kinda thinking your mind was made up before the production began.
I've heard good things about psa AR47 upper recently
I have built 3 of these rifles and all seemed to have the magazine issue but wasn't the magazine I had to Dremel the upper receiver at the M4 ramps each time fixed my rifles
What spring and buffer weight you running? I had nothing but trouble with ASC mags they are garbage sent them back to ASC.
i had the same issues with the c products.. put priority ak 47 + 5 up springs in and took a dremel to the 2 rear notches and flattened them out and polished them ... no more issues with any ammo...
I still have to modify my c-products mags also. It is a shame somebody doesn't make a magazine you don't have to tweak.
I believe one of the main problems of these mags, especially the ASC, is the finish paint, that’s why the follower feels so rough and makes squeaky sounds when pushed down manually.
If they left the metal bare on the inner walls, or better yet, placed the mag casing in polishing tumblers to polish the inside walls and paint only the outer walls, the mags would run much better, like AK47 mags.
I’ve greased the inner walls of ASC mags and the follower moved 5 times better up and down, but I think a better solution would be to use a polishing wheel and polish smooth the inner walls especially towards the top side of the mag, the inside of the feeding lips, and the high points of the ridges, that will allow the steel cartridges to slide much better into position and out of the mag feeding lips.
All that extra work that manufactures should have done in a polishing tumbler, so easily.
U can also put two springs together and slide in
Only C products mags in my 7.62x39 AR, they simply don't die..... and feed any type of ammo ......
Excellent vid. I bought an AR Stoner mag to test my build. What a nightmare. C Products Duramag allowed me to focus on fixing the gas problem. Has anyone else had to open up a 556 spec gas port on 7.62x39?
Yeah my 10.5 inch barrel I had to open the gas port. Was short stroking with a light weight buffer and spring. This was the very last result after I ruled out the mags, bcg. Once I did that I was able to put the regular carbine spring back in the gun and a H-1 buffer. Now it runs flawless and the recoil impulse is nice.
I dont want to be critical here, just an observation. In the beginning when he removed the spring in the ASC mag the tallest portion of the spring was oriented to the rear of the body of the magazine and follower. Then after the mods and the follow up range trip he said the rounds were nose diving and therefore wouldnt chamber. At the range he stated the tallest portion of the spring went to the front of the follower. I wonder if this was the reason one ASC mag worked and the other didnt. I agree my ASC mags needed some minor mods to the body to function properly too. I happen to like your videos and in depth approach to builds. Keep up the good work
The position of the mag spring definitely makes a big difference in the ASC mags, that’s one of the tests I performed while trying to find what was wrong with them.
Did u ever find a 'fix' for the springs the ASC?
I just emailed ASC about all the issues I'm having with their mags. At this point I wish they would just send me 3 springs for 30 rd mags and I would cut them to work with my 20s. Longer than the ones currently in it
Ginsboy2003
Thank you for the video a the tips, however I have one critical question, in the comments below you say that you finally got the ASC mags to work even better than the C Products mags, could you please share what else you did to make them more reliable?
Thanks.
Just buy C Product mags and save time and headache. I really like to improve things but what you really are doing is converting your ASC to C mags
@@battleborn2002 I know, not only ammo and guns but mags too are hard to find. Subscribe for notifications on every website like Classic Firearms and move quickly to get it.
I just sent back 20 30rd, and 2 20rd ASC's. I am having the same problems you were having. Same crap. Scrapes on the casings, bolt passing over the round. Jamming at the front of the mags. I also have a hard time seating the mags when the bolt is closed. My combo is the Palmetto Upper and lower. I tried seating the mags using my brother's Windham lower. Same problems. If you compare them to a D&H or C products 5.56 mag they look the same.
I'd love to get some D&H mags, if they ever ship them out to retailers.
I meant regular 5.56 AR15 mags from D&H. PSA was running mondo deals on them for a whole. Like $6.99+ free shipping if you got 10 or more. Haven't seen that in a while.
perhaps the kinked up portion of the spring on the asc magazine is meant to go to the front to push up the nose of follower? I also notice the retaining/feed lips on the asc magazine are a little bit longer than on the c products magazine which may make for a less ideal feed angle...
Could be that part should go to the front. I was pretty surprised to see the ASC spring about 4-5 inches shorter also. When I removed the material that was cutting into the sides of the cases, it did move the mag lips back slightly, maybe tweaking them upward slightly or moving them back more would help.
In 1911 guns, the front part of the mag lips are slightly bent up to allow the cartridge’s nose to rise slightly and begin aligning with the barrel’s chamber, so maybe bending just a bit the front of the mag lips of the ASC mags, will help the cartridge feed better and avoid getting caught on the front edge of the mag bring that the nose of the cartridge will be just a bit higher when it reaches that point.
Also in regards to the ASC mag spring, flatten the kinked top loop of the mag spring, make it look identical to all AK mag springs and the C Products mag spring, and also install it like all AK springs, with the end of the spring pointing to the rear of the mag, try installing it both ways and you’ll see that one way makes the mag feed much better than the other.
Great video, but not enough there was enough info on the rifle/pistol. If that is a pistol length gas system with mil-spec buffer set up, I would say over gassed and needs a stiffer spring as someone else suggested and/or a heavier buffer. Also, C-Mags need a good slap to properly seat. Once I learned that, Ive had many rounds trouble free on numerous builds with C-Mags. .
I've had issues with my ASC magazine.
very very impressive accuracy. spend the $$$ on the marine corps ar-47 special ops mag, yeah the yellow interior is getting replaced with a rocket red.
why not just bend the lip of the mag up a little?
I could easily see what needed dremeled on the ASC mags so I tweak the feed lips. The C-products mags usually need tweaked as well but don't have half the problems of the ASC mags.
Thanks. I'm a little pissed at myself for buying two ASC 10/30 rounds mag at $30 each. I have five 10 round Duramags that never gave me any issues. I just needed magazine length so I took the chances on the ASC, even though I was aware of their bad reviews. 😔
Thanks for the video, I really appreciate it. You got a new subscriber. Btw any updates on those ASC mags?
get a strike industries long flat recoil spring and right under the feed lips smooth or dremell those damn reinforcing dimples under the feed lips to be smooth that way the rim wont snag on the 2 reinforcing dimples on each side
Did you ever do the other 762ar issue video? About the lugs or something
Not yet.
You should try the uni mag from primary arms. It works great with my ar7.62x39 and it look like a ar magazine not a AK magazine.
I will try one.
Just bought one! Can't wait to try
Hi, you should probably try the c-products 28 round 7.62x39 magazine,. it's in a completely different class being the same size as as the USGI 5.56 mag and more reliable. Thanks
I did plan to try them but I honestly don't have much hope for them since everybody has to modify their 30 rnd mags to get them to work properly.
@ 16:00 you show the front of the follower. I would take 1/8 " off the bottom of the "leg" and smooth the cut, try it again. Mr Guns n Gear had great success doing this with an AK74 mag, look up the video. One other thing I'm not hearing about is Wolff xtra power magazine springs, which would be the first place I'd go after fixing the follower. OK, long vid and you did the spring!
I have C-products grendal. I had this problem for first 40 rounds.. Then it worked flawless for next 200 rounds. Not it is doing this again. Usually bolt goes over round.
How in the hell can you talk about magazines for 42 minutes that's the only reason I didn't finish watching it you answered my question in the beginning C mags are the way to go
For the Love of REASON!! I wondered the same thing about 10 seconds into the video. He says every thing I wanted to know in the first 37 seconds. C Products works great, ASC still won't work reliably, thanks moving on now. Doing research for my first 7.62 x 39 AR Build.
Imagine its 42 min of edited footage. I wonder how many hours he actually recorded lol
Same problems on mine as well
I finally took those mags back to the range. the 30s still aren't working after mods. I think it does need better springs. I purchased a D&H from brownelles. they were the only ones that had them in stock. They're a little pricey $20. When I try them I will let you know
Ok, cool, I thought I checked Brownells.
Ok, I ordered a couple of those myself and can't wait to try them, thanks for the heads up!!!
No problem. Seems like the only downside to ARs in 7.62x39 are magazines! It's too bad because it is one of my favorites.
ginsboy2003 the new D&H mags had one failure to feed. the bullets will nose dive in mags so I sanded the front of the follower and it's a hundred percent now. They work much better than the ASC mags do out of the box.
Seems like it would be easier just to use an AR47 lower so you can use AK magazines, however you'd lose last round bolt hold open...
chrisloUSA you'd also lose the ability to build off of regular milspec uppers
Plus the proprietary lower, upper and bcg to run ak mags alone will cost as much as a actual ak which always runs great
I got an asc 10 round and it has the dents... I cannot even get them out by hand
I wonder if some of the problems noted are due to the pistol configuration. I know that pistol AR are problematic even in 5.56, so I would like to see this same test done with a rifle configuration. I have an ASC 7.62x39 magazine and it has worked without any problems from day one. Anderson lower with PSA upper (using the enhanced firing pin). I'm going to try a C Product also to see if I notice any differences.
The C-products mags still needed a little tweaking. Using an AK mag spring in an ASC magazine seems to be a common fix on the 7.62x39 forums when your rounds aren't coming up fast enough to be picked up by the bolt. With the mags I had, doesn't matter whether you had a pistol or rifle, the metal still needed to be removed so they would work.
I'm working on my 3rd .300 BLK PDW (pistol W brace) and the first two are running 100%. Use the right parts and you'll be fine. One thing I'm not hearing about is Wolff xtra power *magazine* springs, which would be the first place I'd go after fixing the follower
John Mac Howdo U inject mold metal mags?
You don't. They injection mold the poly followers tho.
I've been in injection molding for over 20 years. It looks like your problem with the ASC follower is due to mold damage. It looks like whoever does the molding for C-Products takes better care of their molds. You can tell by the smoother surface and the lack of a parting line flash that you find on the ASC follower. If you ask me, ASC is using an older mold to produce their follower.
That makes sense.
John, appreciate the attention to detail. We take immense pride in our manufacturing and a very picky with our process. this mag in particular is a real point of pride for us. The geometry, the follower, Spring design, and the materials in all our magazines are designed with zero compromise.
C Products Defense I sent some CPD mags back to be replaced because the anti tilt follower on some of the magazines was not working. It has been a month since I have heard anything.
Shamir Roshni please email me directly with your personal and we’ll get it straightened out! Jhall@cproductsdefense.com
C Products Defense I fell in love with u guys 233 and 556 magazines
Good luck finding the C-products mags... Also, you need to be careful with the follower, if it gets too small, it with potentially catch the side of the mag at more of an angle because of the expanded space. So just polish them lightly and knife off the burs, don't sand them down completely. Does that gun have an M4 feed ramp?
Yes it did, but I modified it since then.
Wow nice grouping. How far where you.
I think the issue of the bullet hanging up on the front lip maybe be negated by the bullet being guided upwards by the barrel ramp before it exits the magazine. I would like to see how the bullet travels out of the magazine when installed in the firearm. The other areas on the sides of the mag lips is probably the important issue to deal with. Do you seat your bullets to back of the mag after you load them? how are the mags working now? That was some great groups on the target, what distance were you shooting? What optic were you using?
I seat the bullets to the back of the magazine. The mags work great now after tweaking. I've also learned some people overcome the magazine problems with an extra power buffer spring. I really don't think that is fixing the problem but as long as it works for them. The first optic we put on was a cheap NCstar holo sight. Now I have a Vortex sight on it. My son shoots better with this than he does his AR at short ranges.
Please tell me all the things you did to the mags to make them work 100% reliably, at the end of the video you still had issues with one. Thanks.
ginsboy2003, very good video. when i called R.F.'S they said to use ASC Mag.'s i bought 2 - 16" complete x39 uppers for $199.00 each. so i had worries but they worked but had same issue with the 10 mags ASC i bought from "44mag.com" but i studied them and came up to same that you did. lol. now i have 2 complete 30 cal. carbines for apox. $550.00 each. But since after buying the ASC Mag i bought 10 C Mags and had issues with them out of the box too. But once i did what you did they both work very well now. just wish Magpul would make some x39 mag.'s but after emailing them they said "magpul at this time has no plans making them". So we have to just tweak either mag's till we can get better ones. no big thing. thanks, BTW, nice to shoot .30cal. for .22 cents a round.
I can't understand why'd they'd recommend ASC. When I asked a buddy at work about the two mags, he just said to go with C-Products since they make the mags. for the US military. Didn't research to see if they do or not, but the steel in them is definitely harder than in the ASC mags and quality control is a lot better!
agreed, but i emailed R.F.'s several times about this issue. i didn't want any problems with x39 build then one of their techs gave me a phone number to call. i called him asked how can they sell uppers so cheap, and if their uppers were reliable? he said they buy close outs from all over the place, they open gas port little bit on x39's, give an enhanced firing pin too. then what mag.'s should i get he said ASC mags so i made sure i got them and had same issue as yours but i also figured out same to make them work. i stripped the mag and filed, stoned, front n sides to a mirror finish and all is good. but i have 10, 20, 30 rd's now and in the 30 rder's my spring looks longer than on yours. maybe they changed the springs ? any way good luck with your pistol now hope all is good. BTW, Do you have a video on repairing milsurp wood stocks? like cracks, finishing, bringing them back to good service again? be safe n thanks.
MegaBait56 I'm going to look at my firing pin and compare it to another. I have some Russian ammo I bought 10 years ago that will not fire no matter how many time I rechamber and pull the trigger. Maybe I need an extra power hammer spring. These dang ASC mags shouldn't be kits we have to spend so much time on. I do have a video on the repairs I did on my Nepal Gahendra stock where I removed some rot and filled a crack. It might give you some ideas. In this video I only describe the work but you will get the idea. ua-cam.com/video/0g-Kj2MpGto/v-deo.html
thanks will check it out. if you bought R.F.' bcg you will see it. called "enhanced firing pin" you can even goggle it . they also said for hard primer Russian ammo to use a Wolff hammer spring. forgot to tell ya before.
Since most of the 7.62x39 is made in Russia you'd think they just put it in lol!
Sorry for the criticism. Started watching to get info but i became distracted by improper gun safety. Turn the safety on once in a while. Like when you are done shooting or notice a problem. Thats what its for. SAFETY
Those are great groups. You've got 5/8 of an epic gun. Either lesson the gas (which could result in a fail to cycle) or get a heavier buffer (spring or buffer weight) your mags arent your issue.
Hey Vet. I'm confused by your comment you say to lessen the gas or use a heavier buffer and spring right? If he was to use a heavier buffer with the bolt doing what its doing would make matters worse because he doesn't have enough gas pressure as is.
I had the same problem with ASC mags for my Windham AR 7.62x39. I received ASC mags for my Windham 5.56 so I assumed they were using the same company for the 7.62x39. You know what they say about 'assume'...
WRONG! They were using D&H mags for their AR 7.62x39 and they have worked FLAWLESSLY.
Is there a stiffer spring available for the bolt buffer? This would seem more logical to change instead of modifying all the mags. In a SHTF situation one does not have time to tweak magazines especially if you find a stache in the field someone had concealed.
In a SHTF situation you're probably not going to find 7.62x39 AR mags unless they are yours. Still just not that common. Stiffer spring may cause failures to feed as well unless you enlarge the gas port.
That awkward moment when you just bought 2 FDE 7.62x39 ASC mags for your brand new AR build and then watched this video!!! GD IT! :/ We shall hope and see now. So, Ive had this issue before with an AR10 ASC mag i bought from Midway, it was labeled AR Stoner on their site and its most definetly not Stoner as the mag has ASC on the floor plate and follower. However, i was able to fix the .308 mag by polishing the lips and follower, and dremeling down the tab at the front of the mag, where the neck of the case would catch on the body. Cycles fine now but your left with that feeling of not being 100% reliable. Its obvious that the people in the cleanup department at ASC are permanently out to lunch, the burrs left on that .308 mag were freakin dangerous and they made me laugh out loud. Come on people @ ASC, do your job!! If these 2 new FDE 30 rounders are like the AR10 mag ill be pissed, but ill know at least how to fix them. Glad I have a legit AR Stoner 10 round in case these ASC are bad. Thanks for the video!
Right now, my ASC mags work fine. The C-Products make need work as well. Just takes some tweaking.
You need a heavier buffer spring
One hole doesnt matter if you have a failure.
...... 220 grit is not fine sandpaper at all bro
Get a stronger buffer spring.
AND a heavier buffer.
These magazines are very poorly made, and extremely unpolished. The lip of casing seal shouldnt be getting hung up on metal as it leaves. This is just simply unsafe.
No need to install a stronger buffer spring or heavier buffer weight just need a better mag. Some ASC mags are so out of spec they won't even feed into the lower magwell without modification...!
the round is catching on the dimple in the mag. is your big problem. you can see in a video I did. on how I fixed them.
it is a nice clean video. thanks for your time.
I planned on addressing it also, but the case mouth was also hitting hard. A slight ramp fixed that. I'm take care of the dimples as so many other people suggested just to make them more reliable.
It’s absolutely the ASC mags fault. I have 2 20 rounders and they are so rough in function. I haven’t even built my AR yet and I know they won’t work. The followers tilt like no tomorrow . The springs have sharp edges binding on all interior indentations. Rounds tilt and dip when loading. I’m sorry I bought them. Absolute crap.
Looks like the original spring was deformed causing it to nose dive..
AR-15 7.62 X 39 no problem using the ASC mags 30 round or the Stoner 30 round mags Flowless screw the C mags
C-Product mags for 7.62x39 are the only way to go . ASC mags are paperweights and after the purchase the company doesn't care about you they don't return emails if you have a issue that might cost them money . I mean they're fine for the range if you only put a few bullets in at a time .. maybe the C stands for California compliant? ASC overpriced and they don't work. Save some $ and stress go with C products
I mean you can go to the ASC UA-cam page where they review their own 7.62x39 magazines and the comments are TURNED OFF that should tell you something right there
Nice Review, Thanks.... C Products ONLY !!!
ASC mags are trash. I ordered 10 and they all came with spread feed lips and rounds would just fly out once I loaded about 6+. I had to crush all the feed lips back together. After using these mags for some time, I noticed the front lip of the mag was flaring our from the rounds being smashed into the wall of the mag(7:10). These mags are just simply trash imo.
Umphhh???
There stainless steels work perfect! They use a magpul style anti tilt follower. The aluminum which i didnt watch full way but bet u have there have the old style mil-spec followers that are junk!
If you watch the first 2min and last 2min of this video, you will know absolutely everything you need to know 😂
Looks like you need a brace to stop you from "limp wristing" the pistol
You said "look at how much more tension the C Products spring has than the ASC spring has". But all we can see is the different 'length'. We cannot 'SEE' 'tension'. 'Tension' must be felt. Just because one spring is longer doesn't mean it also has more tension. It may, but it also may not.
Not the mags' fault. ASC mags function FLAWLESSLY in my Palmetto M4 7.62*39
You're limp wristing causing the bolt to not have enough inertia to follow through (like a 12ga semi auto shotgun). The lack of a brace is one thing; i would also get a heavier buffer and spring.
Bad mags a lot of ASC mags are so out of spec they won't even fit into the lower magwell without modification, the last 3 mags I have dealt with had to have several windings cut out of the spring due to excessive follower tension...!
Seems like you have a crappy gun I shoot the cheapest ammo out of either mag and have no problems
Who is the throbbing member stomping around and dropping stuff while you are filming. Amazingly annoying.
I dont like your gun safety at the range. You are pulling the trigger several times while not looking down the sights or braced for the shot. This is an accident waiting to happen, especially with an unreliable weapon.
