B.A.D. 9mm Bolt Carrier Group | Blowback Enhanced | Nitride
The Battle Arms Development 9mm Blowback Enhanced Bolt Carrier Group delivers exceptional reliability and smooth cycling for AR-pattern pistol-caliber carbines chambered in 9×19. Machined from durable 8620 steel and finished in a deep Black Nitride treatment, this BCG is engineered specifically for straight-blowback PCC systems that demand consistent mass, proper geometry, and rugged construction.
Enhanced for 9mm Blowback Systems
The carrier features a removable internal weight, allowing builders to tune recoil characteristics or match various buffer configurations. Its dedicated 9mm extractor and full-mass profile help maintain dependable extraction and improved bolt velocity regulation—key factors in blowback-operated firearms. The ramped rear surface also supports compatibility with standard AR-15 hammers, making it suitable for a wide range of PCC builds.
