Bushmaster Bolt Carrier Group

Recommended Posts

Look for something with standard phosphate finish, bolt made with Carpenter 158 steel that is shot peened high pressure tested (HPT) and magnetic particle inspected (MPI), internally chrome lined carrier, gas key properly staked. That Spikes Vicious quotes is fine. If you're a milspec fanboi get a BCM otherwise you'll never hear the end of it from the real "operators".

aim has a 79 bcg that is 9310, shot peened etc etc....buy that one....


mipofox....how did that dpms bolt do?



Still works fine. Can't say as much for the gas port which I burned through on DSA chrome-molly 11.5" HBAR. Also destroyed 75% of the baffle on the PWS FSC 556 comp on it, but it still shoots sparks 5' each side so I'm sticking with it. I've certainly beaten the snot out of it. DPMS bolts at one time had (have?) a poor reputation, though. It's a fun upper, not a theater defense weapon :)
