Choosing the Right Silent Captured Spring
Вставка
- Опубліковано 29 сер 2024
- Rounding out this series on operating system components, we have, by far, the source of the most tech questions we field around here. Which Silent Captured Spring do you need for your rifle? A number of factors play into this, but it's simpler than a lot of people think.

Everyone is complaining about the difficulty of the topic, but this video is the best supplemental source of information available...watching this video, in addition to a careful reading of the documentation JP provides on the website, does appear to answer all the questions most people have.
If I understand JP correctly with regard to selecting the proper buffer/spring combo:
- If the priority for a rifle is reliability, then increasing the buffer weight is the best initial approach. JP provides a flowchart to assist with this.
- If the priority for a rifle is recoil mitigation (in order facilitate the quickest recovery of the sights onto the target), then using a heavier spring with a lighter buffer weight might be the best initial approach. Sprinco claims to have empirical data to support this approach as well (they are a company that makes excellent springs...which could imply a bias...but JP SEEMS to substantiate this claim).
All choices have tradeoffs. It seems that the tradeoff for a lighter buffer mass would be a greater chance of the rifle failing to go into battery, and the tradeoff for a heavier buffer mass is increased recoil impulse (delaying sight recovery onto the target).
Based on the information available from JP and Sprinco, it seems that most rifle tinkerers need to understand the following (with various exceptions relating to poor rifle design/construction and weak magazine springs):
- If your rifle 1) reliably strips each round from the magazine, 2) the brass consistently ejects at 4 o'clock, 3) AND the bolt always locks back on the final round of a magazine, then your gun is gassed properly for that ammo. There's no need to modify it from there. In that case, you MAY want to get the JP SCS version of whatever you have in your gun if you really just can't stand the sound of the action spring during the cycling of your rifle.
- If you're going to be running a broad range of ammo types, then you want to make sure your rifle has the appropriate buffer/spring combo, in order to meet all 3 of the above criteria for the weakest powered ammo you are running. This means that it will be overgassed for some ammo, but it will always cycle with even the weakest ammo you use.
Thanks for the heads up. Took my 8” 300BO unsuppressed H2 for the first time. One fail to load. Bolt holds open on last rnd. But ejecting at 5 oclock. Going to try lighter spring but unsure.
Thank you. This complemented the video very well for me. Thanks for the breakdown
Very helpful explanation thanks
Super Big thankyou for that breakdown
@@Doc02864you have the h2 for a short 300bo? did you change any springs?
Just finished up this video. Probably the most important video for AR hobbyists to watch. Excellent job, gentlemen.
Update:. So I installed a tungsten weight on my SCS in my cloned LRP-07 that was unlocking prematurely running the VMOS BCG with SCS, 6.5CM 22in. Supermatch barrel, JP AGB, etc..
Completely fixed bolt opening prematurely and brass is coming out very clean now! Rifle is consistently locking back on last round and cycling great!
Thank you guys, THIS was the info I needed to get my cloned LRP-07 running reliably suppressed! Much appreciate!
I have both Arma spec and JP silent capture and I can't tell any difference between either one if you long as you have one of the two you're doing great..... if you can afford a JP that's great, if you can only afford Arma spec you're still doing great
I know the company says to use the H2 weight buffer for a suppressed SBR but I found that the bolt catch wouldn't lock back on an empty mag, even with a wide open adjustable gas block. I suggest buying the least expensive SCS as it may work just as it should and you aren't paying extra for some tungsten weights that may not be needed. I wish I did that. 😑
Made the same mistake lol
How to make any standard ar15 feel like a much higher quality rifle.
How is this better than say a Geissele buffer spring?🤯🔫💸
@@KaneGregory thats a good question 🤔 I wish I knew
@@KaneGregory IT doesn't rub against the buffer tube by design.
That flow chart was exactly what I needed. Thank you!
good to know my intuition was right on. running a 2a palouse lite rifle with an icrw G3 low mass steel bolt. ordered the scs2-15 with a spring pack for further tuning. also using a superlative arms adjustable gas block. after my modifications, the rifle will be sitting at around 4.3 lbs down from the stock 5.3 lbs. With a scalarworks mount and aimpoint t2, it'll be at 4.7 ish lbs, with a huxwrx 762ti, it'll be back to stock weight of around 5.3 lbs (and i have an h2 captured spring in my PWS, but i don't think it'll need it because of the flowthrough nature of the suppressor).
Dollar for dollar lighter than a vseven while maintaining a forged receiver set, sitting just above 5 lbs with a dot and suppressor.
Either my comment in your last video on large frame BCGs was just coincidental timing or you guys went over all the info i was asking for but instead of responding you guys made a video!
Thank you very much for this, looks like I will be ordering a couple tungsten weights for my LRP-07 clone I built running a Omega 300 with JP 6.5CM barrel, JP detent AGB, VMOS H2, and SCS H2 and also have the spring kit.
I threw the lightest spring in this past weekend and retuned it to lock back on last round. Carbon on brass is really bad with either springs so GREAT info! Thank you guys, much appreciated!
I have a small frame 8" 300blk suppressed and law folder. Yikes my head hurts lmao 🤣
This is ridiculously helpful, thanks guys.
How do I double like this video? Great information! Really enjoyed the the in-depth specifications!
Very informative.. great knowledge..👍🏼👍🏼
Thank you 😊
So much great information
I think there's so many other companies doing the same thing but i feel with them you get what you pay for and they just look and feel cheap in comparison.
I have bought 2 then used them in the AR 15 uppers in 7.62x39 - 17 Remington - 223 - 6mm x45 they are no different than using the buffer and spring set up.
Still makes noise also .
no shit it makes noise
So there is no difference between the stock buffer and spring and this one on the 7.62?
It factually cannot make as much noise as a buffer/spring combo. The sprint is bent up and scraping all the walls of the buffer tube at all times. With this system, that no longer happens. It will rub a bit on the capture rod but not nearly as much as rubbing the buffer tube.
My h2 buffer is awesome!
My 14.5 mid length Noveske needed the ar10 springs to cycle at the 3:30-4:00. Using on different platforms it seems like the springs are lighter than normal
So I have the radical firearms ar15 mid length gas system. 16in barrel. Chamber in 556. Any idea what I should run? I’m just a little confused on all of this lol. I am assuming just the JPSCS2-15 but I don’t want to run into any issues. Anyone have any suggestions?
Good explanation , tganks
Where is the best place to start to get the softest shooting 3 gun rifle? Currently running 16", lightweight BCG, adjustable gas block, standard weight SCS. If I would tune this to be even better what would you recommend? Gas, buffer weight, buffer springs?
great video! Actually learned a thing or two, thanks for that. My current sbr build is on the verge of "dude you're doin way too much" and a killer battle rifle if i could iron out the kinks. Its a billet 5d tactical lower, machined by me, 11.5'' 5.56 nato upper, carbine length gas system w/adj block, billet slick side receiver, skeletonized lightweight Browning BCG, 7''x1.5'' modular can aslo machined by me, fostech echo sport trigger, and a standard carbine buffer and spring. shes slightly overgassed, but only during high fire rates in the echo position (which is screaming fast btw with this setup) and occasionally fails to pick up the next round from the mag, click empty chamber. i love the concept of the scs and im hoping you have a recommendation or 2 as to which kit and if itll help it be a little closer to reliable. thanks
Lol just started using a 5d jig and router myself xD got like 3 different builds half put together now haha
@@rachelstephens3680 From my experience, 5d's router setup is about as reliable as it gets when it comes to the finished product and machining accuracy. As long as I keep from doin something stupid, I know once I put a fresh blank in the jig it's going to come out ready to assemble without any headaches.
I installed a JP "standard", My AR 15 began to "double feed - one in the chamber and one in the bolt chamber. I do have an Adjustable gas block on the gun before installing the "standard" JP..
Would that be from serious "Bolt Bounce", causing the bolt to slam forward so hard, it bounces back far enough to feed another round? Is this scenario caused by the spring being too stiff, weight being too light, or both? Did you find a solution? Thanks in advance for any replies. Cheers
Not enough talk about the large platform. Cool video though. I love JP products
Doing it right now!
JPRifles! QUESTION!
Will you eventually make one that works with the folding adapters like from Sylvan Arms and LawTactical? From the way they seem to work I didn't think they'd work with that plug being in the way. Thanks! ✊🏼🇺🇸🇺🇸🇺🇸
If
2 steel, 1 tungsten = H
1 steel, 2 tungsten = H2
3 tungsten = H3
Then what is the H rating for the all 3 steel rings that come in the JPSCS2-15 package?

What do I need for a DD Mk18 and RC2 suppressor and a folding Law T pistol brace? 10H or the 15H?? I ordered a sprinco blue and a H2 buffer and then saw this. I was going to use the stock carrier that is at .70 but need to know if you guys suggest an adjustable carrier bolt or something else. I want to able to run both unsuppressed and suppressed as cleanly as possible. Semi auto.
I believe you are looking for the H2-LAW. It sounds like a specific request, reach out to tech@jprifles.com.
Ammo used in this was Hornady Black 208 grain A-Max (Subsonic) & It's a Custom Built AR Pistol I built from top to bottom.
My issue is I got one of these for my 10'' 300 blk out, in H2 weight config. My plan is to suppress it at some point. HOWEVER, if you dont supress it with the H2 config (2 titanium, 1 steel) EVEN with a adjustable gas block. I could get it to extract the shell casing but not rack another round without having to manually do so.
I'm guessing this is a spring issue as in spring weight is to heavy? OR is it i can use the spring that came with it and i need to use 3 steel weights so its standard until i suppress?
Very frustrating day at the range.
AFTER watching more of this video I'm seeing its a weight issue....thank god I ordered the SS Weights yesterday and I'll be changing those out to run subs even though at this time I'm not running it suppressed just yet. I also already have the spring set cause i bought it with the scs when i got it. So I'll start with the SCS Weight change to 3 Stainless to try and get the bolt to rack another round and achieve lock back (without manually locking bolt to the rear). If need be like you said do a 95% weight spring and go from there. THANKS!!!!! Helps out a lot!
I have a 12.7 x 42 .50 cal Beowulf 10.5" barrel with a pistol length gas block and an AR 15 lower, what size weight would you recommend as a starting point with one of your SCS's?
Send us an email to Tech@jprifles.com and we can get one of our experts to help you
One thing I'm not sure I understand...when is bolt bounce an actual problem on semi auto rifles?
Bolt bounce will topically move the bolt out of battery just enough so on the next shot you get a light firing pin mark on your primer and you end up with a misfire.
What about 9mm? Want to upgrade my Aero EPC for competition. Do I need a JP BCG or is the Aero EPC BCG ok?
The rifle i just built is so undergassed that I have to run a suppressor in order to get lock back on 5.56 and I have to run the suppressor on .223 in order to even pick up the next round in the mag.
I put an h2 in it at first but I’m skeptical that dropping down to a carbine weight will actually fix it because its so undergassed.
I am having issues with some rounds not chambering completely using the standard captured spring. I ordered a couple of tungsten weights to see if that helps.
Make sure your scs moreso your buffer tube is installed far enough into your lower. Depending on that info you might need to thread the buffer in a turn or two, could even throw a quarter in the buffer as a shim to move the scs so it has good contact with the BCG when closed
My Carbine buffer (Savage MSR15 Patrol) weight is 2.8oz. My brass is being tossed closer to the 5 O’clock position than 4-4:30. Should I go to a H or H1 Buffer? All I shoot is NATO spec 5.56.
Shoot us an email at Tech@jprifles.com
ok ..do you have to remove the bolt carrier weight .. what the best weight for a 9mm direct blowback system ?
Yes, the slide passes through the rear of the bolt, so the 9MM bolts with weights will need to be removed. The weight required changes according to your setup. Give us a call and we can help you find the best for your setup. 651-426-9196
Sounds like a lot of issues. Heating bolts. Multiple parts. Screwed together. 😩
Looking for a Silent Capture to go into my HBPDW for 300Blk. Any suggestions?
Does anyone know if the Gen2 scs screws be reversed? The only two screws on the Gen2 scs.
Can you advise what configuration I can buy for POF REVOLUTION 308?
The Silent Captured Spring system is not compatible with the POF REVOLUTION 308.
What product show I select for a 16" mid length .750 fsb gas block and a2 birdcage(5.56) also using areo precision bcg and as for ammo used it's. 55 for range with friends and 75-77gr when using rest of time

I just got mine in but now I'm questioning if it's the right one. I'm running a 16 inch with an h2 currently, suppressed and a radian suppressor charging handle. No shorty stock but standard buffer tube. The only difficulty saw was the polymer end am I wrong?
How about providing a link to the flow chart? The link in the notes above goes to a list of all the buffers but no flow chart (that I can find).
Flow chart is about half way down the Selection guide. jprifles.com/document_pdfs/SCS%20Selection%20Guide_880.pdf
@@JPRiflesGot it. Thanks so much.
Do you make one for the Maxim PDW?
I was thinking about getting one of these SCS systems. Im running 16" 223/556 Carbine Gas System with Springco Blue & Spikes T2 Buffer (4oz). Right now it ejects at about 3oclock and as long as im not running TulaAmmo it doesnt have any feeding issues. What size SCS do you guys recommend H or H2?
You could run the Standard or the H2 for this depending on your personal preference/rifle setup. Give us a call if you want help narrowing it down more than that. 651-426-9196
@@JPRifles thanks for reply. I bought the standard. Rifle isn't complete yet but after it's built and I get it tuned ill just order the Tungsten weight if needed. Thanks

What about gas operated ARs like the DDM4 v7 from Daniel Defense suppressed? Would the small frame 15H2 be the correct one even though it’s a gas operated rifle?
Yes the 15H2 (JPSCS2-15H2) is the model we would suggest for that rifle with a suppressor.
I have stock Tokarev TBP 12 I am look to install a JP Enterprises Silent Captured Recoil Buffer Spring Assembly. I would like to know which you would recommend.
What spring power to go with on the jpscs?
My friend has a adams arms non adjustable mid length piston AR in 14.5” with adams lightweight carrier that reduces the bcg weight by 2 ounces compared to a milspec bcg. Should they just use the ejection pattern chart to make a proper buffer weight and spring combination? He is looking to reduce recoil and is wondering if paired with the lightweight bcg if you go with h2 buffer with standard spring or go lighter buffer weight and/or lighter buffer spring as well. Any input is greatly appreciated! I’m thinking h2 with the 80 or 85 spring due to the lightweight bolt carrier?
Is there an option so if I'd like to swap from suppressed to non suppressed without having to switch the buffer or have another one of these on standby? Honestly not the biggest fan of the old fashioned flexing all over the place buffer springs and like how this system is a solid piece that isn't going to flop around if anyone has any idea what would work best honestly I don't care about recoil or anything like that regardless of recoil or anything else I just man handle the shit out of my rifle to the point the end of my shit ain't gonna move regardless if I'm shooting .22 all the way up to 308win. Like I said I just want all of my equipment to be solid and not warping everywhere and the way this one looks honestly looks solid enough I could cut an area out for it in my rifle case to set it in there if I need to buy 2 I guess I can have 2 different cut out sections and find a way to label which is which.
No need to switch back and forth, you can tune the gun to run with or without the suppressor.
What's the lightest buffer weight you can configure it? I'm currently running a 1.7oz buffer. Rolls the brass out in a nice neat pile about 2' from me at 4:00. I have run a .59 oz buffer but never could get the bolt velocity low enough to feed reliably.
I just ordered a JPSCS2-10H2 and spring kit for an 8.6 Blackout carbine build (16" barrel). I used a Geissele Super 42 spring and H2 buffer. I didn't install an adjustable gas block. I have one so if necessary I can change out the gas block. It ejects but dents the case mouth, the case lands at about the 1 to 2 o'clock position, and the bolt doesn't lock back on the last round. I weighed the buffer and it weighs 4.3 oz. My form 4 for a Dead Air Primal is at least 6 - 7 months out based on current status info. I plan to shoot this suppressed all of the time but shooting the Gorilla Ammunition supersonic loads, or my reloads, aren't off the table. The info on your site says the weight is 6.6 oz. Is that assembly weight or buffer weight? I'm looking forward to trying your system.
i have a suppressed 10.5 with a silencerco specwar. it gases me out like crazy gets in my eyes chokes me out. i have your JPSCS2-15K-H2 kit with the lightest spring installed on it. my gun runs with my adjustable gas block open 1 click away from fully open if i go 1 click more closed it dosent run. should i get a heavier buffer or put a heavier spring in it. id love to bring that gas down to where im not getting so choked out i can only run half a mag before my eyes are burning.
What's the has port size?
Did you figure out your problem? If so what was the fix?
Is there anything that makes this family of rifles not annoying when using earpro. I HATE boinging bullets.
.458 socom running 350gr to 405 grain full power handloads. My upper is a 16" bear creek arsenal 458 socom and my lower is a mossberg MMR hunter from back in the day with the mossy oak Finnish in an A2 style Buttstock. I also use the lower with a 20" 556 upper. It runs flawlessly with both right now so why fix it's not broken I don't know curiosity I guess. What would be the best silent capture system for the 458?
I have a 8.3" 300 blackout. Running subsonics mostly suppressed but would like for it to run unsuppressed at times. What buffer weight would you recommend?
you need the standard scs 15, id get the extra springs as well for further options.

Yes- How much depends on caliber and rifle setup. Give us a call and we can help further 651-426-9196
Has anyone actually sound tested these setups? Assuming you’re suppressed and subsonic do we actually have data that proves the overall sound of the action is quieter with these? And like quieter enough to be more ghostly than the next guy.

What would you guys recommend for a 6arc, 24" +1 gas with adjustable gas block? A standard 3 SS mass version?
I'm looking at acquiring a 300 HMR. It mimics a 30-30 WIN. What would you suggest for a spring rate?
Where can I find this jp flow chart? Can't seem to find it with Google
What about adding weight to the bcg? In combination with the buffer system
We already have that option with our VMOS bolt carriers.
what about .45acp suppressed with an 8in barrel?
My bcg cycles, ejects and locks back flawlessly but when I rapid fire it I can only get 5 or maybe 6 rounds off rapidly before it pauses. The bcg is forward, round is chambered but I get to 5 or 6 fast trigger pulls and the next fast trigger pull nothing happens but then the very next fast trigger pull it fires. It’s like it skips a trigger pull ever 5 shots approximately. Normal shooting it fires the entire magazine flawlessly. What is causing this to happen?
It’s an LWRCI 300 black out shooting 110 grain with the stock H2 buffer and spring. I’m firing as fast as I can pull the trigger when this happens. It’s a new AR so if anyone knows please tell me what I can do differently, thank you.
Did you ever figure out your issue?

300 BLK super sonic on pistol gas opens too early, and rips the case out while pressure is still high in chamber and brass or steel case is yet to shrink back down.

Thanks for a very helpful video. What temperature to heat the allen head screw to melt the loctite?
Go to Loctite's website or Google it. Since there are several varieties of Loctite, each one has its own procedure for removal. Example; Blue doesn't need any heat to remove it and is considered temporary. Red does need a certain amount of heat in order to remove screw/pin/etc.., and is considered permanent. There are other colors that represent different attributes according to environment they are used in. Example; high heat/damp/water exposure/etc.. I would start with the Red Loctite removal temperature and go from there. You can pick up a marker style pen that's called a "Temperature Stick". They are found at welding supply stores, (maybe hardware stores too), that will only melt at set temperatures, whicheavea a mark on the item once it reaches that markers set temperature. If you get a 200 degree marker, it will begin melting/marking the item once it reaches 200 degrees. They are very cheap in case you don't have a infrared thermometer or other devices to check temperature readings. I would recommend getting another temp marker that's 50 or 100 degrees less than the set temperature you need. This is just so you can have an indication of when you are getting close to your set temperature, preventing you from overheating the item any more than necessary. Sorry it turned into a book, lol, but it may help others. Temperature Markers are basically unknown to the mass majority. Cheers

"melts at set temperatures, WHICH LEAVES a mark on the item...." ** NOT "whicheavea a " .lol. wtf? Sorry bout that. Lol

Are these really worth the money?
Yes
What actually does the buffer do , what are the benefits ??
Thanks 👍
It eliminates all the extra friction of the standard buffer spring scraping along the inside of the tube. So, shooting with it is smoother and less noisy. It's also reconfigurable and tunable so you can dial in the buffer system for your particular rifle as well as tweak the cyclic rate to what you like.
@@JPRifles ....I may check 1 out and I'll call for expertise help with my rifle specs ...
Thank You
What do you recommend for a Ballistic Adavantage 14.7 inch barrel on a rifle geared tword duty use, with Federal 55 grain Tactial bonded? Don't care about the noise. A soft shooting gun would be nice, but it's secondary to reliability. I'm assuming the barrel isn't short enough to qualify as an SBR.
Why can’t you guys just do a video showing these systems NOT explaining it because explaining it isn’t helping. I’m the type of guy that needs to see it….. also you seriously need to start with the LF rifles. You say ultimately its the users parameters I guess maybe this system was a bit to advance for me. I own the SCS and the JP BCG to for my 308 AR but I just don’t know enough about it to trust it enough. Also is it normal for a 500+ dollar BCG to have the finished come off after the first cleaning????? Because I swear I have a brand new JP BCG with 5 rounds on it I still have all the original packaging and the DLC finished came of the dam thing wth is that???? Actually I think I’m going to do a video about this issue myself.
Interesting. Make the video. I want to see this.
Was supposed to be some magic you used
I have a rifle length gas tube and a guieslie super 42 H, witch is the same as an H 1. Your talking about 3 Ounces?
And extra springs.
So it's hit and miss.
This seem stupid
What about rifles with an A5 recoil system?
We make an A5 spacer that you would use with the Silent Captured Spring system.

Can i run one of these in a HBPDW from SB tactical?
Look into the maxim pdw brace / stock. Jp and maxim have a proprietary silent capture spring system for that.
what configuration to replace a ar-15 rifle buffer you recommend?
Missed... why and how. Silly kids
Sounds like you are about to spend upwards of 400 bucks buying 2 different buffers with the spring kits whenni can buy an H H1 H2 and H3 from bcm for 100 bucks total
That is incorrect. Once you have the Silent Captured Spring system, you can modify the buffer mass and spring rates. You do not need to buy a whole new Silent Captured Spring system.
flow chart makes no sense to me
This flowchart is designed to help users determine the correct JP Silent Captured Spring (JPSCS) for their rifle based on several factors related to their rifle's configuration. Here's a breakdown of how to understand and use this flowchart:
1. Identify Your Rifle's Frame Size:
- Small Frame (.223/5.56 or smaller, including .300 Blackout):
- This category is for rifles chambered in smaller calibers like .223/5.56 and .300 Blackout.
- Small Frame (6.5 Grendel or larger, excluding .300 Blackout):
- This category is for rifles chambered in larger calibers within the small frame category, such as 6.5 Grendel.
- Large Frame (All calibers):
- This category includes rifles chambered in any caliber that requires a large frame, typically larger calibers.
2. Check for Special Configurations:
If your rifle falls under the small frame (.223/5.56 or smaller), you need to check if it has any of the following special configurations:
- Short-barreled rifle
- Suppressed
- Select fire
- Piston operated
- Using an H2 buffer
If any of these configurations apply to your rifle, you will be directed to use a specific model of the JPSCS (JPSCS2-15H2 or JPSCS2-10H2).
If none of these configurations apply, you'll use the standard JPSCS models (JPSCS2-15 or JPSCS2-10).
3. Determine if Your Rifle is Biased for Low Mass Operation:
This step applies to both small and large frames.
- Low Mass Operation:
- If you are setting up your rifle for low mass operation by using one of JP's low mass bolt carriers (JPBC-1, JPBC-3, JPBC-4, or JPBC-8), this affects which JPSCS you should select.
- If YES (low mass operation is used), you'll select a specific JPSCS model designed for that configuration.
- If NO (standard operation), you will use the standard JPSCS model for your rifle's frame size.
4. Final Decision:
- For Small Frame Rifles:
- If your rifle has any special configurations, choose between JPSCS2-15H2 or JPSCS2-10H2 based on your barrel size.
- If your rifle does not have special configurations, choose the standard JPSCS2-15 or JPSCS2-10.
- For Large Frame Rifles:
- Follow the same process to determine if you need the low mass option or the standard JPSCS for your setup.
5.Important Note:
- For rifles designed to run subsonic .300 Blackout ammunition, regardless of the configuration, the JPSCS2-15 should be used.
@@JPRifles still not sure about which to get have no idea what you mean by special configurations this is what i have 300 blk out 16 inch barrel have no plans on using a suppresser will be shooting sub sonic and super in it
which do you recommend
this could be made simpler if you would list each separate instead of a flow chart of them all coming together
@@tombuchanan3971 Thanks for your question! I understand that the flowchart might seem complex, so let me simplify it for you.
Based on your setup:
Caliber: .300 Blackout
Barrel Length: 16 inches
Shooting Both Subsonic and Supersonic
Since you are shooting both subsonic and supersonic rounds and don’t plan to use a suppressor, you should select the JPSCS2-15. This model is ideal for a standard .300 Blackout setup with a 16-inch barrel, covering your needs without requiring special configurations like suppression or short barrels.
For a quick reference, this option is suited for small-frame rifles chambered in .223/5.56 or smaller calibers, as well as the .300 Blackout.
We appreciate your feedback on the flowchart, and we'll consider it for future updates. Feel free to reach out with any more questions!
Im sorry, but your flow chart sucks. It doesnt address piston systems enouph and other issues
Springs aren't difficult to figure out!
You need to be a ricket scientist to figure out what you need.
This should make the gun fire stupidly easy for this much going on
I tried an H2, but it slowed it down so much that my trigger finger started outrunning the bcg.
Where is the best place to start to get the softest shooting 3 gun rifle? Currently running 16", lightweight BCG, adjustable gas block, standard weight SCS. If I would tune this to be even better what would you recommend? Gas, buffer weight, buffer springs?
