Wilson Combat AR-10 Bolt Carrier Assembly .308 Win Nickel

Heat, fouling, and hard-running .308-based rifles are where bolt carrier details start to matter. This AR-10 bolt carrier assembly is built around a polished nickel boron finish for easier cleanup and corrosion resistance, with a 9310 tool steel bolt and an 8620 hardened steel carrier.

Wilson Combat also calls out the parts that usually get scrutinized on a large-frame setup: a properly staked gas key, plus a machined ejector and S7 extractor intended to handle the pressure of hot .308-based calibers. It is used in Wilson Combat fully built rifles and fits a broad spread of .308 Winchester-based chamberings, including .308/7.62x51, .243, 6.5 Creedmoor, .260, and .338.
