Manufactured in-house, the Faxon Duty Series 5.56 NATO 16in Pencil Profile AR-15 Barrel is fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
Quality is imbued into Faxon barrels from the start. Faxon starts 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.
