The Faxon Firearms 9mm PCC barrel (brand part number 15A910N10NLQ) is a 10.5-inch, light-taper AR-15 barrel built specifically for blowback-operated 9mm pistol-caliber carbines, not gas-impingement 5.56 uppers. Faxon cuts it with a 1-in-10 twist rate matched to standard 9mm bullet weights and finishes it in a durable nitride coating. The barrel is threaded for a compensator or suppressor, uses a .750 gas block diameter for parts compatibility with standard AR components, and features an 11-degree target crown to protect accuracy at the muzzle. At roughly 1.03 pounds, it keeps a PCC build light on the front end.
