This Rise Armament bolt carrier group is a .223 Remington/5.56 NATO BCG machined from 4140 steel for AR-15 platforms (brand part no. RA-1010-BLK). Rise Armament finishes it in black Nitride, a coating that resists corrosion and cuts friction for smoother, more reliable cycling than a standard phosphate finish. Built to standard AR-15 bolt and carrier dimensions, it drops into any mil-spec upper receiver. It’s a solid, no-frills upgrade or spare BCG for a 5.56 AR build.
