Literally the best example you gave was at the end with the 2 barrels that made it easier for me to understand! Thanks again man I love all the products. I hope you guys can get your orders caught back up.
Great video, Mike! The system works. My friends and I were able to jump from target to target at ridiculous speeds because of the reduced recoil, and the AR pistol didn't get dirty quickly. At least not until someone busted out the Remington ammo. Feel the burn, Remington!
Seem like a much, much simpler delay system than roller delay blowback in much, much more expensive firearms, though it does look like CMMG has started to get a bit proud of their product as to pricing. It’d be awesome to get these systems at a price to be able to feasibly build a decent one for less than a grand. FWIW I have a ton of respect for CMMG’s product development.
Wow! What an excellent, descriptive, informative video! You guys are really "on track" with some great, innovative designs and development! Great American Ingenuity, from a Great American Company. Congratulations and Bravo!
Great video and explanation! Helped me make up my mind and I purchased a CMMG MkGs 9mm Glock 16" Resolute 300. She's a beauty, Midnight Bronze and the build quality is awesome!
AWESOME Video!!!! I just went to my Friends Gun Shop with another Friend so he can pick up his CMMG 5.7MM. It is REALLY BADASS!!! So I'm DEFINITELY going to pickup a 4.6mm SOON!!!
I wasn't too sure about all this fancy stuff you guys created so I went to gun Jesus (forgotten weapons)... he's the best sales person a manufacturer could ask for. I wasn't sure if I wanted to go with a cmmg set up after my last build (all jp enterprises parts) but between multiple calibers and a tunable less recoil system I think these uppers will be the go to for me in the future
I admittedly know very little about the subject, but out of pure curiosity, if you could, please answer these questions I have: -A bit of exposition first: I know the radial-delay banshee line of guns is mainly composed pistol-caliber firearms (9mm, 45acp, 10mm, 5.7x28 and 4.6x30), but I can't help to think of the HK roller-delayed family of firearms. Could the radial-delay system be used for rifle calibers (say .223 and .308)? would the pressures be too high? how would it compare to roller-delay? would it require less weight in the bolt carrier and recoil spring? and, I know this might not be possible for you to answer, but still, are there any plans for producing rifle-caliber radial-delay firearms in the future? Loved the video! I think the radial-delay system is an amazingly ingenious way of adapting the already existing parts of the ar15-type rifles and carbines to work without needing gas operation or the extra weight of straight blowback, just by, and pardon me if I am over-simplifying it, cutting the bolt lugs at an angle and cutting matching angles in the chamber.
Sold. Take my money. I have a boat load of uppers and lowers (556,308 & 300). I loaded up 20k 9mm, but only had a 1911 in 9mm. I ended up buying a Kel-Tec Sub2k in G19, so I had to buy a G19 as well. I love the fact that I can plink 4in steel all day long at 95M with the Sub2k. The AR 308s and 556 destroys the chains. Ive been looking at 9mm AR builds for the last 5 years, all straight blowback. Gimmick or not. Im sold on the gimmick.
Is there anything different about the barrel compared to a normal DI barrel besides no gas port? Im curious how or if it would work with the 9mm bolt and a 7.62x25 barrel.
As cool as a .300 blk banshee would be, it would probably only work with subsonics, since radial delayed blowback probably can't stand high pressure rifle rounds, but I'm just assuming here and would love to be proven wrong haha
The force on the back of a cartridge is way way higher with rifle caliber rounds so direct impingement means the gas doesn't start to unlock the bolt until the bullet passes the gas tube. With radially delayed it would happen immediately.
@@3darms can you just make the lugs bigger and further delay the action as for the ammo maybe we can use something like Sig's new 6.8 hybrid catridge that has a steel bottom and brass body to prevent ejection problems?
What bolt mass would you recommend for the 5" barrel Banshee 45ACP running a rugged obsidian suppressor, and what mass does it come installed with? Thanks!! Looking forward to getting mine!
So I’m very interested in your barrel and bolt carrier bundles for 9mm radial delayed blowback but I’m curious as to if another manufacturer’s upper and lower are compatible for 9mm. I have a very specific one in mind or else I’d just buy your completed upper.
So I'd have to buy cmmg upper? I have a new frontier 45 acp lower and upper. Right to bear has cmmg barrel and bcg in stock. Was going to purchase. My question is do I have to use cmmg upper reciever?
It may require some tinkering. We've played a little bit with some various adapters, and the ejector and feed ramps (if they have them) will need to be removed. Mag seating height could be an issue too. We've seen some mags feed fine (primarily Glock OE) with some cheaper polymer mags don't.
Does the CMMG 5.7 x 28 radial delayed blowback still require coated ammunition in order to feed and extract? Reloading 5.7 x 28 is pain in the ass because of the plastic coating. It would be so much simpler to just throw it into a tumbler.
Probably a dumb question, but how does this system differ from the CZ Scorpion? I know they are entirely different platforms, but maybe explain effectiveness. Thanks.
I have a MK9 lower receiver. Can I utilize the This system with that lower?. I understand that I'll need to get the buffer tube that coincides with this design. Just trying to figure out which buffer tube I need.
Does it need a spring in the rear of the bolt??? If needed,how does it work?? I don't fully understand which of chamfer and can pin rotates the bolt...!! In AR-15, cam pin forces to rotate the bolt when the bolt carrier goes rearward. Please,Can you explain me 3D view of radial delayed blowback system..!!
Yes, it still needs an action spring. You can go to our website and click the Technologies tab, then Radial Delayed Blowback. There's a good 3D animation there that may help.
That's great, but why not just go DI? ie what's the advantage of any delayed blowback design over a DI or piston setup? I'd love to build a 10mm AR pistol, and the radial delay seems like a neat idea, but I'm still wondering how it would compare to a DI or short stroke piston 10mm?
We've not tested using their system. Curious about the spring rate. The weight of the buffer likely won't be a problem. Different spring rate could be.
Wonder why the banshee mk4 can't be converted into a 45 acp or 10mm? You can get it in 300 blk out, 5.7 but then the next caliber that it can be converted to drops all the way down to a 9mm 🤷♂️ I would like something a little cheaper to shoot but not have to lose a bunch of stopping power. Not that the 9mm doesn't have stopping power obviously.
Quick update on my buddy's 9mm CMMG. It still doesn't work, but now it ADs. He handed it to me this week to try it. I pulled the trigger, nothing happened, so I let off the trigger. A second later, BANG! Absolute trash.
Hi, do you know if the CMMG ARC mags can be loaded with an ETS speed loader (or any other speed loader for that matter)? That is one of the criteria i have for going with the CMMG banshee
Hey i got a cmmg 22 conversion kit. I polished the rails n feed ramps cause only complaint I saw was some people had feed issues. No issues with feeding but my aftermarket trigger doesnt like to set the primer off. Any solutions? I polished the firing pin and spring too havent tried it yet to see if it helped
I'm currently trying to get my radial delay blowback upper to work with a 9mm Colt style lower. It really seems doable. So far I've removed the lower ejector. Then what I see next is the lower feed ramp side and the magazine lips are about 1.2mm too high for the bcg to pass over it. I've trimmed down a cheap mag and I think I have good clearance with that, next is the feed ramp. Will this ultimately work, has it been done yet, or am I wasting my time?
@@scottkimball4225 the hardest part for me right now is trimming and adjusting the mag feed lips and getting the mag to run smoothly. My set up is the 9 radial delay bcg/barrel in an Aero upper and then attempt to mate it with a Spikes Colt 9 lower. I have to say the upper ran awesome on my standard lower with the Pmag conversion. I just wish they made the conversion for the 40 round Pmag, if that was a thing I might scrap this project.
So basically your saying i dont need a gas system or a buffer kit? I just purchased the barrel/BCG combo of yours from Primary Arms! Its awesome i paid for the speedier shipping and its packed awesomely and the cleanest looking barrel i ever bought!! So if i dont need a gast system or buffer kit im living with a much cheaper set up! :>)
@@CMMG Thanks but i purchased your barrel/BCG combo chambered in .45ACP....? hehe I did contact your company via email/customer service and Bryan told me that i should use a Carbine length buffer and an H1 buffer which i believe is what a standard AR Carbine chambered in 5.56 comes with normally right? I did buy a pistol caliber specific buffer kit.....so im guessing we will see? lol I also have a .224Val AR i built but it has a Carbine length buffer and kit on it so i am in the middle of replacing that with a fixed rifle stock and buffer kit. I hope it improves its cycling and helps with its accuracy a bit? or it may just be me who knows?ROFL
Ive been trying to explain this to my brother. He's looking at a blowback 9mm upper (cost reasons) but I'm trying to talk him into your radial delay system. Do you offer a military/veteran discount? His wife's ret. Navy & he's a contractor for coast guard. Thanks!!
So all the resolute/banshee 9mm's that have been going out aren't delayed? Did this system disappear with the "guard" series and now it's back? I always wanted one of these systems and I guess I'm glad I haven't gotten one yet. This looks like the way.
I wonder how CMMG was able to patent something discovered by Von Mannlicher in the late 19th century. For full power rifle cartridges as he was using it, IIRC it was not practical.
The two CMMG RDB 9mm uppers I've used had very snappy recoil like a straight blowback 9mm AR but were very unreliable. One was my buddy's upper, which he returned to CMMG and they said it was faulty and replaced it. The replacement is the other one I've used, and it also doesn't work. I really don't like straight blowback 9mm ARs, but at least they work until they hammer themselves to death. I have a CMMG 22 AR upper, and it doesn't work. My other buddy bought a CMMG LPK for his AR, and the trigger doesn't reset. They're 0 for 4 in my book. I think the CMMG RDB could be really cool, if it worked, or did any of the things they say it does. But it doesn't, because the operating system is total garbage. Look at their slow mo in this video, and check out the ejection pattern on their gun. It's random. Some rounds bypass the shell deflector. On my buddy's gun, almost all the cases bypass the deflector and some hit him in the face because he's lefty. The guns just don't work. I'm glad they showed how garbage their guns are in their own advertising. Check out how repeatable the blowback action is in comparison.
You just need to make sure that your Glock lower doesn't have the feed ramps and ejector built in. Those will get in the way of the RDB system. As stated, a lot of times those are removable, but we still don't test with others' lowers to be able to guarantee compatibility.
@@CMMG ok I'm new to this. I have a regular ar-15 upper and traditional 9mm lower. Can I use that system with you bcg/barrel combo? I am also going to suppress does barrel length matter as far as suppressability or is it just a preference? Thank you for the reply!
So could this system support rounds like .223 in the future or is it just too much pressure for it? I would actually be very intrigued to run a .223 chambered pistol build with no gas tube so I can cnc a custom extra slim handguard.
I’m going to shoot mine and after 1000rds I will give you my input on my CMMG M17 Banshee my hope is she passes the test. . .Im not a big fan of propriety stuff in, let’s find out, 07 of 2022
The Banshee looks amazing, but quality control sucks from my perspective. I purchased a Banshee MK17 9mm and from the first magazine, the trigger reset is garbage. In my first outing I fired 100 rounds….probably 40 times the trigger failed to reset. Not sure I got more than 2 or 3 rounds in a row to fire. The gunsmith at the range took it apart and fiddled around with the safety and the trigger, then lubricated everything. But no real improvement. I contacted CMMG and they basically said I can send the gun back for repair (would take several months due to back log) or they will send me parts and I can try to fix it myself. I am reasonably handy, but not a gun smith. This sucks for a $1600 gun….all these reviews are positive….but they sell me a lemon and will do nothing about it. Don’t waste your money.

I'm hoping they do a 357sig & get some hot rounds from Underwood. I think that cartridge would benefit immensely from the radial delay design.

I believe they offer a 10% off for military.
So I cant just buy the radial blowback BCG and add it to my AR9?
not without some modifications to that lower
I feel CMMG is missing out on a big opportunity by not targeting specifically for PCC competition audience.
Do must M16 shooters swap out the buffer weight for heavier?
Shouldn't have to, but if you need to tune it, you can. Standard carbine buffer is what our Radial Delayed Blowback systems operate with.
So its kinda like an stg44 design?
is the 7.62x39 banshee also delayed blowback?
It is not. It is Direct Impingement

You just need to make sure that your Glock lower doesn't have the feed ramps and ejector built in. Those will get in the way of the RDB system. As stated, a lot of times those are removable, but we still don't test with others' lowers to be able to guarantee compatibility.
CMMG if I could I’d buy a fully built set up but sadly those are not legal here. My only option is to build on what I have available in Connecticut
They sell a bolt group & barrel for 350$ to 400$ , you can catch a sale sometimes and get one for 300.. its well worth it
Does the radial dent the brass at all?
the system doesn't, but since they could bounce off the brass deflector, it could
Do I need to check head space of I build my own
We would definitely recommend doing so. While it's usually not needed, the extra peace of mind goes a long way.
@@CMMG even if chose blow back. 9mm upper build
Do I have to use a specific barrel with the BCG?
For Radial Delayed Blowback, yes. They only come together as a set.
@@CMMG ok I'm new to this. I have a regular ar-15 upper and traditional 9mm lower. Can I use that system with you bcg/barrel combo? I am also going to suppress does barrel length matter as far as suppressability or is it just a preference? Thank you for the reply!
When are y'all gunna start makin' AKs?
@ahsido1 we're working hard to keep up... promise!
Roller delayed blowback is still king.
10mm is best mm!
So could this system support rounds like .223 in the future or is it just too much pressure for it? I would actually be very intrigued to run a .223 chambered pistol build with no gas tube so I can cnc a custom extra slim handguard.
Make that Banshee in 10mm
I’m going to shoot mine and after 1000rds I will give you my input on my CMMG M17 Banshee my hope is she passes the test. . .Im not a big fan of propriety stuff in, let’s find out, 07 of 2022
I can't wait for my AR-Pistol.
HOO T HOO...bang
i wish i had money get cmmg on police pay cannot afford it got fox mike 3 inch with discount 260 and endomag
The Banshee looks amazing, but quality control sucks from my perspective. I purchased a Banshee MK17 9mm and from the first magazine, the trigger reset is garbage. In my first outing I fired 100 rounds….probably 40 times the trigger failed to reset. Not sure I got more than 2 or 3 rounds in a row to fire. The gunsmith at the range took it apart and fiddled around with the safety and the trigger, then lubricated everything. But no real improvement. I contacted CMMG and they basically said I can send the gun back for repair (would take several months due to back log) or they will send me parts and I can try to fix it myself. I am reasonably handy, but not a gun smith. This sucks for a $1600 gun….all these reviews are positive….but they sell me a lemon and will do nothing about it. Don’t waste your money.

You sound like an annoying “pitch”
Does youtube commenter of the week win a new Endeavor 300, MK4 chambered in 6mm ARC?
Nfa wait times on rdb parts. Wtf over 😳
It's not just RDB parts, it's pretty much industry wide. Nobody was ready for the demand over the past 1.5 years.
The difference? The CMMG price gouging for radial delayed blow job 👎🏾
