This Q&A makes me realize how far behind I am on understanding the compatibility of ar parts when attempting a build. 🤯 gotta start somewhere though! I'll catch up eventually. 😂 love my cmmg resolute. And so does everyone else that sees it!! 🎉👍
Thanks for educating on the theory of standard vs radial delayed blowback. Glad I’ve listened to these videos and done my research before building my AR-45 build. That said the cMMG MKG is no doubt the best option for minimal recoil, durability, and most importantly reliability👍
Very happy with my 300 series Banshee 10mm now. Whatever the ejection problem was, you guys fixed it. When I got it back in November, I took it to deer camp, and did some test firing-rapid fired 2 30 round mags of 180gr Hornady XTP's without a hiccup
I used your 9mm bolt & barrel combo with a stripped upper, just wallered out that ejection port till it cycled gud. I use it on a FOxtrotMikes glock lower, just removed the ejector and it runs like a dream.
I just bought the 9mm RDB back 8-inch barrel, and I am putting folding stock on it. I do have the weight set and 2 different weight bolt extensions for the folding stock adapter. I'm running mostly +p and +p+ ammo but do have some cheap stock ammo to also run. Is there an overall weight to try and get to. The bolt extensions are light one at 1.6 Oz, and the other is 3.4 Oz
Will the radial delayed system work with 5.56? There are advantages to not using a gas operated rotating locking bolt, you get the full velocity of the round with no gas robbed to rotate the bolt, the radial delay system looks like it wouldn't wear out as fast as some of H&Ks roller delayed systems
yeah i sure hope that your barrel/BCG combo work with the uypper i gave you the link too? I have another that is almost its twin but wasnt listed as a dedicated pistol upper? so
Can I use your radial delayed BCG and Barrel kit with a PSA ARV receiver set so that I can use scorpion mags? Do you know any reasons why it wouldn't work or do you know if anyone has ever done this before? If you know that it doesn't work then do you know of any AR9 receivers that use scorpion mags and are compatible with your bolt and barrel?
It doesn't that we are aware of. There are grooves in the bottom of the carrier that would align better with Glock or AR magazines. Scorpion magazines are significantly wider.
as long as you have the RDB bolt and barrel from cmmg you can pretty much use any pcc glock lower as long as you remove the extractor i preferred the circle ten or angstadt arms because of LRBHO and about 200.00 dollars cheaper than cmmg their extremely proud of their products.
Amen to that, @Kahunaification! I own the CMMG Mk57 BANSHEE 200 5.7x28mm Pistol. Absolutely NO NEED to perform Frankenstein experimenting on a firearm that ALREADY runs flawlessly. As they say to those Frankenstein surgeons,... curiosity always kills the cat.
Can I put a 9mm radial delayed blowback upper reciver on a normal ar-15 lower reciever? The one I'm looking at on your site comes with the ar15 conversion magazines so I assume it would work?
Are there any plans to make a 40 rounder or drum 9mm conversion magazine for the MkGs? I love mine but I'd like more than 30 to get through a USPSA field stage without having to plan a reload.
Why does your radial delay bolt not come with an extractor o-ring? You carry this part# 55BA475, why not include them in the bolts? Is it because of it being a pistol caliber round?
Is there any interest in making a BCG system for .410, 20ga or 12ga? Would love to see an AR shotgun made by you guys that just looks and works like an AR, with standard AR parts. Please 😆
Have the 5.7 bolt and barrel kit installed doing pre-checks. Checking headspace with the bolt stripped, I noticed the bolt won't go past the locking lugs and rotate with the "go" gauge in (from Pacific Tool & Gauge) - is this normal and how best might I check headspace if so?
You could, but the twist rate isn't quite right for the best accuracy in a .22. Plus you'll likely foul up your gas system if shooting nothing but .22 out of it.
@@reeper26 If you have a dedicated barrel, you'll just need to change the chamber adapter on the conversion to what we call a collar. It's designed to interact with the dedicated barrel.
Building a pcc 9mm sucks. Too many “off-ramps’!!!!!. This doesn’t match that. That doesn’t match this!!!! I hate that I started spending money, before, truly understanding, the mess that I was getting into!!!!!!’n
You encountered one of the big challenges of building a straight-blowback AR PCC, there is no standard. This is one of the benefits of the CMMG RDB as it can use a standard lower configuration, including the FCG, and standard upper receiver.
Not sure what process you’ve been trying, but if you just want to order a spare, you can order one on our website. Just search Mk57 firing pin. Unfortunately YT will not allow us to put the link. Or it can be ordered direct from our sales team. There’s no order form needed. If it’s a repair part, that goes to our Tech Support team and they send a replacement. The only exception to the above would be if the parts leave the US. Since we cannot export directly, it would be going through an exporter and subject to whenever they place an order.
Have you considered making a functional product? I'm real tired of thieves hand prepping a few guns to work, shipping them out to popular reviewers, and then dumping nonfunctional stuff on their customers. If you can't make functional kit for everyone, don't steal their money.

Great Q & A !
Thank You .
Great information brother. Thank you!
Great gun I have a Mk17 8inch 9mm so far so good, the test of time will determine, but I still dont like proprietary anything just my 2 cents. . .
I can't get enough of my Banshee MK4 9MM..I will soon get a .22lr conversion for my AR
CMMG is like the Caterpillar bulldozer of guns.
Love cmmg
Thanks Mike....

Where did you purchase your bolt and barrel? I can’t find them anywhere.
@@johnpalmer8834 from their website over a year ago. These things take time.
Also, do you have time to talk about Jezus Christ our Lord and Sabre
Was the ejection port standard size to begin with?

Thank you for this video. A question I have is: Will a Fostech Echo AR-II trigger function properly in your MK-47 platform?

Ordering fromm cmmg is like buying a suppressor, you might get it in 12 months......

I found it easier just to buy the final product from CMMG and not try the Frankenstein approach to firearms

Yes, but anybody can do that. I enjoy the challenge.
Hello
Can I put a 9mm radial delayed blowback upper reciver on a normal ar-15 lower reciever? The one I'm looking at on your site comes with the ar15 conversion magazines so I assume it would work?
You are correct! The conversion mags allow the Radial Delayed 9mm upper on a standard AR lower
Could you please do a video on glock mag height for your bcg in 45acp
Have you tested radial delay with rifle-style buffer systems?
Would there be an issue with the cam pin in a Gibbz side-charging upper?
Do a special about the .950 JDJ.....
Are there any plans to make a 40 rounder or drum 9mm conversion magazine for the MkGs? I love mine but I'd like more than 30 to get through a USPSA field stage without having to plan a reload.
Why does your radial delay bolt not come with an extractor o-ring? You carry this part# 55BA475, why not include them in the bolts? Is it because of it being a pistol caliber round?
Building a 10.3" on an ar15 platform,, will a standard matched upper & lower work with your radial delay bcg?
Following
It should if you have a cmmg bolt, barrel & mags and be sure it’s a 5.56 mil-spec upper.
I have a question have any rifle calibers been tried with the radial delay action
I just want to know what you style your beard with, Hoppes or CLP?
Hoppes. Always. 😉
That multi-cam setup tho.
How much of a turn does the Bolt actually do when in full Battery? Is it locked into place when like a Lug on a bolt action locks in?
With the chamfered edges of the bolt, it never actually "locks". It just rotates into its location.
Is there any interest in making a BCG system for .410, 20ga or 12ga? Would love to see an AR shotgun made by you guys that just looks and works like an AR, with standard AR parts. Please 😆
The shotgun isn't the tricky part. A reliable functioning magazine is.
5" barrel standard .45, 10" suppressor. which weiggt should I use? ?
Have the 5.7 bolt and barrel kit installed doing pre-checks. Checking headspace with the bolt stripped, I noticed the bolt won't go past the locking lugs and rotate with the "go" gauge in (from Pacific Tool & Gauge) - is this normal and how best might I check headspace if so?
What 80% lower work with your uppers
Can you use the .22 conversion as a dedicated bcg for an upper?
You could, but the twist rate isn't quite right for the best accuracy in a .22. Plus you'll likely foul up your gas system if shooting nothing but .22 out of it.
@@CMMG yeah I would use a .22 barrel. I have a spare lower and the bravo kit sitting around and wondered if I could make it a dedicated bcg.
@@reeper26 If you have a dedicated barrel, you'll just need to change the chamber adapter on the conversion to what we call a collar. It's designed to interact with the dedicated barrel.
CMMG is so hawt right now

Here's a fkn question... WHY IS IT SO HARD TO GET A QUOTE AND ORDER FORM FOR A RDB 5.7 BCG FIRING PIN?.... BEEN WAITING SINCE MARCH 🤬

It could be the best product ever but your company can't meet demand so it pretty useless!
When will y’all make a 7mm rifle? I want an endeavor 7mm really bad. Please help!
