Nice !!! I bought a Bushmaster two years ago. Standard M-4. After noticing that the gas key and castle nut were properly staked, I took it home. That was a couple of thousand rounds ago. I'm still waiting for my first stoppage of any kind. Ran it for 500 rounds without cleaning once, the gun didn't care, it never missed a beat. A half a century ago I hated the AR-15/ M-16. Now they would be my first choice to carry into battle.
