I'm thinking it's a mag issue. I had a brain fartand was thinking promag was pmag so I was not thinking it was a mag issue. But now I do.

Definitely this.

I also have a new DPMS Gen 2 AR-10 with the bull barrel. On the second range trip it developed a major failure to feed issue. As in at least one round out of five, in every single mag. I only loaded 5 rounds into the mags as I was doing ammo accuracy testing. Eight different brands of ammo, three bullet weights, same mags as before when it ran fine. I took it to Clandestine who diagnosed it as being severely over-gassed, so I installed an adjustable gas block today. And I ordered some OEM DPMS metal mags for it. Strangely enough, the mags arrived yesterday in a box from Remington Ammunition Co. WTF is up with that? The blister pack on the mags said DPMS, but they came from Remington. Guess they must be a subcontractor. Anyway, we'll see how things run next time I can get it to the range.

Remington, Bushmaster, and DPMS are all owned by Freedom Group.

Customer service was okay, wish they had put me in touch with a gun person. the person I talk to might as well been my wife.
The gun is very a good shooter, but I got the expensive cmh upper.

Not necessarily. Everything I've gotten from PSA has been fine. Keep that AR 10 well lubed and it will shoot great.
