The Battle Arms 9mm AR15 Bolt Carrier Group, Black (Battle Arms Development part number BAD-BCG-9MM) is an enhanced blowback BCG built for 9mm AR-15 pistol-caliber carbines. Battle Arms Development machines this BCG for broad compatibility, working with both Colt and Glock magazine configurations so it fits whichever lower pattern the build uses. A reliable AR-15-style extractor claw with an O-ring and spring backs up extraction, and ramped bottom geometry gives it broad trigger compatibility across different fire control groups. The charging handle interface on the bolt carrier surface is built to withstand vigorous pulling force without shearing off the carrier key, and a reinforced firing pin is retained with a standard firing pin cotter pin for reliable, repeatable function.
