Faxon just can't help not accepting the status quo. Bolt carrier groups are available aplenty, but few could meet their exacting standards for performance and value. Seeing current offerings as just the starting point, they set out to ensure the best options are available for our demanding customers.

Improvements include cuts to ensure both Glock and Colt-style lower receiver compatibility. The key is machined directly into the bolt carrier - no fasteners to check or worry about. Finally, they keep the full-auto compatibility for use with new binary-style trigger systems.

Note: 9mm Blowback Pistol Caliber Carbines typically require the use of a heavy-style buffer. Ensure you are using a heavy enough buffer for maximum reliability and safety.

Note: Bolt carriers ordered and deployed with barrels not specifically checked by Faxon for headspacing MUST be checked to ensure safe and reliable function. Faxon recommends Pacific Tool & Gauge headspace kits for all measurements. For detailed instructions on headspacing, see our blog post for instructions.
