The Faxon Firearms 9mm PCC Blowback Bolt Carrier Group Gen 2 is a purpose-built carrier designed specifically for 9mm AR-15 pistol caliber carbines running blowback operation. If you're running a 9mm PCC for competitive shooting, tactical drills, or just plinking, this is the kind of component that makes the difference between a reliable platform and one that gives you headaches. Faxon listened to feedback from their original design and packed this Gen 2 version with practical improvements while keeping what worked.

The dual GLOCK/COLT-compatible geometry means you can drop this carrier into either style lower receiver without modification. The ramped carrier bottom plays nice with any standard trigger, so whether you're running a milspec trigger, a match-grade competition unit, or something in between, you won't have fitment issues. The extractor has been upgraded to an AR-15 pivoted and sprung design—a move that adds reliability over simpler blowback setups. A stronger firing pin and standard cotter pin (rather than a proprietary setup) make field maintenance straightforward. The carrier key is separate from the charging surface, a smart design choice that prevents sheared keys under heavy use.

Built from MIL-SPEC 8620 steel and salt bath nitrided for corrosion resistance, this BCG is built to run. The removable weight system plays well with JP Enterprises and similar buffer systems, letting you tune the action to your preference. Full-auto geometry means it'll cycle reliably in any configuration you build. At 14.9 ounces, the weight is engineered for 9mm blowback dynamics—neither too light nor too heavy for consistent operation.
