Faxon Firearms Gen 2 9mm PCC Full-Mass BCG – AR-9 Pattern Pistol Caliber Carbines

The Faxon Gen 2 9mm PCC Full-Mass Bolt Carrier Group is engineered for reliable cycling in blowback AR-9 pattern pistol caliber carbines. This full-mass design provides the weight necessary to properly manage recoil impulse and ensure consistent ejection in direct blowback 9mm systems. The Gen 2 iteration addresses common PCC issues with improved extractor geometry and enhanced bolt face support for reduced wear on both the BCG and barrel.

Machined from 8620 steel with a salt bath nitride finish, this BCG delivers corrosion resistance and reduced friction for smoother operation. The nitride treatment penetrates the surface rather than coating it, maintaining tight tolerances while extending service life. Installation is drop-in for standard AR-9 lowers and compatible upper receivers—no fitting or modification required. The full-mass configuration is specifically designed for carbine and pistol-length blowback systems; consult your firearm's specifications to ensure proper buffer and spring pairing.
