Faxon Firearms 18" Gov't/Socom 5.56 NATO Rifle-Length 4150 Nitride / Melonite Barrel Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle to grave, these barrels are fully stress-relieved, air-gauge tested, and 11-degree target-crowned to ensure superior accuracy. Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel undergoes a battery of tests at each operation until it is finished in Nitride, and is finally inspected. All barrels are individually checked for headspace using precision, custom-hardened gauges.
