Rise Armament RA-1011 AR-15 .223 Rem/5.56 NATO Bolt Carrier Group - Black Nitride

The Rise Armament RA-1011 Advanced Bolt Carrier Group is a complete replacement or upgrade component for AR-15 and M16-pattern rifles chambered in .223 Remington and 5.56x45mm NATO. Its full-auto-profile carrier is also compatible with forced-reset safety selectors, forced-reset triggers, and registered full-auto sears.

The assembly combines an individually magnetic-particle-inspected 9310 steel bolt with a heat-treated, case-hardened 8620 tool steel carrier. A tool steel gas key is secured with Grade 8 hardened fasteners and properly staked. Additional components include a 4140 steel cam pin and a shot-peened tool steel extractor.

Each bolt carrier group is individually inspected and MPI tested. The black nitride finish provides an easy-to-clean exterior and a uniform black appearance.
