I recently built this cqb/truck gun chambered in 5.7×28 with the cmmg barrel and radial delayed blowback bcg the system actually runs well if you can keep the mags filled lol this must be corrected these mags are not cheap!!!

Load it right hahah
Do you think taking the feeding system and all the other stuff out and putting it in a pmag or something would help?
I wonder if you loaded an ar the correct way and knew how to run a rifle….
1.) I wonder if putting some sort of Epoxy on the feed lips would stiffen them up. Sounds like the plastic is too dang soft for the forces.
2.) We should file a lemon lawsuit against CMMG if they do not take fast corrective action. This is insanely unreliable for something that people could be trusting their lives to.
I see you wasnt a fan of the clip, but i have ro get that set up. Can you share any All the modifications you did to get your Rifle to that point , the suppressor , and the sights Because that sounded good Thank you for your videos
Thanks for posting this.
Damn that sucks for all of y’all. Maybe I got lucky. I bought my mags from primary arms separate because I was just testing a build. Maybe primary had some from a good batch of polymer. The endo mag company allegedly makes these for cmmg and I’ve heard of people just getting custom mags made directly from them. I bought the cmmg 5.7 barrel and bcg from km tactical and used a aero precision ar upper and rail I bought from brownells awhile ago that I never got a chance to build. Put them all together and it runs like a sowing machine. One thing I’m finding out about a lot of newer ar mags is to not load them all the way to capacity if you’re gonna insert the mag on a closed bolt. A lot of pcc’s in particular will void your bcg warranty if they can prove that’s causing any issues with your bolt or mags.
I just uploaded a video of the same issue. I bought 3, they replaced them and all three replacements do the same thing. I agree that metal feed lips would solve the issue.
Initially, I was told that it was a bad batch. The new ones held ammo for few weeks but I never even had a chance to shoot the gun. I’m hoping that on Monday I’ll get in touch with their warranty department and have them take the defective mags back and sell me a mk57 lower so I can use the FN mags. Or sucks that I have to spend more money on a lower since I’ve already invested so much into my build but I really like the 5.7 and I already have their expensive bcg and barrel.
Those mags 🗑💩 where can I get reliable ones
I got 5 mags. They all did this. I sent them back and jumped the gun and got three more. The "repaired" ones I got back did this. The new 3 pack I got did this. Pretty sure there's a reason why FNH only makes 20 rounders for the FiveseveN and why the p90 mags do that weird swivel thing. Fucking 900+ bucks deep and im prob gunna have to sell it. I'll wait until they replace the EIGHT (8) mags and see if those work or not. Also: if you barely push down on the tip of the bullet you can pretty much empty out the magazine.

So… I had one on order… and I saw this a while ago and asked them about it.
They said they had an issue and had fixed it
I look in my center console…. where I keep a loaded mag. Rounds everywhere.
I had feeding problems with mine….maybe I need to break them in more
Now this is a gun channel I’d watch lol
I AM A LICENSE MANUFACTURER AND THINKING OF INCORPORATING THIS WITH MY AR15 FLATFORM BUT MIGHT NOT HAPPENED BECAUSE OF THIS. I WISH THEY HAVE A METAL MAGAZINE, BUT PLASTIC IS THE WAY TO MAKE MONEY I GUESS.
I CAN TELL YOU, THEIR IS NO CRACK AT ALL, THIS PLASTIC IS A SOFT POLYMER. FIRST TIME I USE IT IN COMPETITION TODAY AND I M SO DISAPPOINTED. I CAN NOT BELIEVED IT, THEY NEVER EVEN TEST THIS PRODUCTS BEFORE IT GOES OUT TO THE PUBLIC. I LOOK IT THIS WHEN IT ARRIVED AND NOTICED THE PLASTIC ALREADY BEING SOFT IS NOT LIKE MAGPULL. AT THE RANGE IT PROVES IT.
I am having the same issue.
Damn I was about to buy this kit. So glad I found this video. I really want a 5.7 pdw.
Did you get it sorted? Happy with it after all?
Lmao Hold on there sir while I fix my mag. I request temporary cease fire at this time.
Sorry for the problem you're having there. If you could, please contact our Tech Support team at techsupport@cmmginc.com. There may be a small crack on the feed lip that was missed. We'd like to help fix this for you.
That’s been happening with some other brand magazines here lately make you wonder
