Purpose-built for 9mm AR-15 pistol-caliber carbines, Faxon®'s Generation 2 PCC Blowback Bolt Carrier Group the features of their popular first BCG while adding modern improvements. Faxon maintained the dual Colt/Glock-compatible geometry, user-removable weight, full-auto compatibility, and a "ramped" bottom that accommodates common triggers, while adding new and welcome features.
The extractor has been upgraded from an internal 1911-style claw to an AR-15 pivoted and sprung option. For ease of disassembly, a standard firing pin cotter pin is used, and to ensure long-life, the carrier key is separate from the charging surface, ensuring that the carrier stands up to any vigorous action. No sheared keys! A stronger firing pin rounds out the new changes.
