The Aero Precision APRH100615 Complete 5.56x45mm NATO AR-15 bolt carrier group in black nitride is a precision-engineered component built for shooters who want a reliable, low-maintenance BCG without compromise. Whether you're assembling a rifle from the ground up or upgrading an existing build, this black nitride-coated carrier delivers the durability and performance that serious AR-15 shooters expect from Aero Precision.
Built from 8620 steel for the carrier and 9310 steel for the bolt, this BCG is machined to mil-spec standards and shot peened for strength. The black nitride finish is engineered to reduce friction and minimize the reliance on frequent lubrication and deep cleaning—a practical advantage whether you're running suppressed, at the range, or in the field. Forward assist serrations are cut into the carrier, and the gas key is properly staked with Grade 8 hardware to ensure it stays put through thousands of rounds.
The bolt features mil-spec design with an MPI mark confirming its quality. The extractor comes with a black o-ring insert and Viton O-ring for reliable brass ejection. All the small details that matter—proper gas key shrouding, shot-peened surfaces, and precise machining—are here because Aero Precision knows that a BCG is the heartbeat of your rifle's reliability.
