Faxon 5.56 NATO 7.5″ SOCOM Barrel

Faxon’s Duty Series 5.56 SOCOM Barrel

Manufactured 100% in-house from gun-barrel-quality bar-stock, the Faxon 5.56 NATO 7.5″ SOCOM 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 Faxon 5.56 NATO 7.5″ SOCOM barrel is individually checked for headspace by precision custom hardened gauges.

Faxon Pencil barrels are the lightest in the industry. Don’t just taken their word for it, major companies like Robar, Kaiser US, 2A Armament, and others choose Faxon Pencils for their ideal balance of weight and performance.
