Good cheap micro upper - ABC RIFLE COMPANY AR-15 7.62x39mm 5in Barrel Custom 5in Top Cut Custom M-LOK Handguard Complete Micro Pistol Upper Receiver w/BCG And Charging Handle

First off this thing is fun! Looks and shoots great. Gas key looks like it was staked right. Feels very comfortable in the hands. Ran perfect with a super safety. The mlok and picatinny rails are how they should be. This thing kicks pretty hard though, would have preferred a muzzle brake to come on it.. I had one light primer strike but im using cheap steel case ammo so it’s not surprising. Would purchase from them again
