"Not a bad BCG for the price. Good staking job on the gas key, minimal machine marks, ejector spring has buffer and o-ring. Everything you'd expect from a mil-spec BCG. My only gripe is the Parkerizing was really rough on this one. I ended up taking some OOO steel wool and some oil to smooth it out. After that, it worked nice and smooth. Good for a budget build."
