AR 9mm Enchanced Bolt Carrier Group BCG CMMG

Complete, drop-in carrier/bolt assembly is ramped on the bottom to provide clearance for a factory .223/5.56mm hammer in your 9mm conversion.
Eliminates the need to install a dedicated 9mm hammer, so the original fire control system stays intact for easier conversion back to original caliber.
Precision machined from high-grade ordnance steel, the one-piece design combines bolt and carrier as a single unit to provide outstanding strength, durability, and reliability.
Includes a staked-on carrier key.
