7.62x39 C.A.P.S. Mid-Length Piston Upper with Magpul MOE M-Lok Handguard

Is this for real? Never thought I'd see an x39 in AR platform that runs 20 cent rounds FLAWLESSLY. Only hick ups were user error because I was using a lower with a polymer trigger group. Switched to 2 different lowers, one with a Geiselle match trigger and one with a standard military trigger. Slammed out 400 rounds without a single misfire using Wolf Mil-Spec HP ($209 for 1000 rounds). I even picked up some Wolf hammer springs but it doesn't seem I'll need to install them. 2 1/2" groups at 100yds (most shots are less than that with a few fliers due to the powder variance of cheap ammo). Extra props for fast shipping and EXCELLENT customer service!

While researching other uppers chambered in 7.62x39. I thought I would possibly have to change the bcg and firing pin make it reliable. That’s not the case with this upper. First time out fired several 30 round mags with no issues. It is quality built and shipped quickly.
