Faxon Firearms Duty Series AR15 Barrel 5.56NATO 1:8 Twist 4150 Nitride - 16" | Socom Profile | Mid Length

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 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.
