FAXON Duty Series 10.5in Gov't/Socom 5.56 NATO Carbine-Length 4150 QPQ Nitride Barrel (15A58C10NSQ)

Manufactured in-house at Faxon, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy. Quality is imbued into Faxon's barrels from the start. They start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.
