Faxon 9MM 4.5″ Taper Carbine Blowback Barrel

Faxon 9mm PCC barrels are Colt & Glock compatible!

Manufactured 100% in-house from gun-barrel-quality bar-stock, the Faxon 9mm 4.5″ Taper Carbine Blowback Barrel starts with 4150 Chrome Moly Vanadium Mil-Spec steel. From there, the barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. This beautiful 9mm PCC 4.5″ Taper Blowback barrel is individually checked for headspace by precision custom hardened gauges.

Faxon barrels are manufactured in Cincinnati, Ohio under their ISO:9001 and AS:9100 quality certifications.

*Note – Faxon Firearms advertises its barrels by their legal length. Pistol Caliber Carbine barrels have the chamber built into the barrel “extension” area, which makes them about ~1″ shorter than centerfire rifle barrels.
