Works great on my AR9 build. by Teeto, Verified Owner, February 7, 2024
Good weight to it, extractor is nice and it works great with my aftermarket drop in trigger. A lot of AR9 BCGs don't work well with drop in triggers.

Product Info for Faxon Gen 2 9mm PCC Blowback Full-Mass Bolt Carrier Group, Glock/Colt Compatible

Purpose-built for 9mm AR-15 pistol caliber carbines, our Generation 2 PCC blow-back carriers keep the features of our well-loved first BCG with modern improvements.  We maintain the dual COLT/GLOCK compatible geometry, user-removable weight and full-auto compatibility while adding new and welcome features. We maintain a "ramped" bottom so any common trigger can be used - ideal for competitive shooters and plinkers alike. image

The extractor has been upgraded 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.
