Faxon Duty Series AR-15 Barrel 5.56x45mm NATO 16" Gunner Contour 1:8" Twist Nitride Integral Muzzle Brake

Overview

The Faxon Duty Series AR-15 barrel is chambered in 5.56x45mm NATO with a 16-inch length, a 1:8 twist rate, and a black nitride finish. Manufactured 100% in-house from certified 4150 GBQ steel, each barrel undergoes QPQ nitride coating for exceptional durability, magnetic particle inspection (MPI) to verify surface integrity, and air-gauge testing to guarantee superior match-grade accuracy. This barrel features an integral 3-port muzzle brake, eliminating the need to independently pin and weld a muzzle device while allowing full assembly and disassembly of the barrel and barrel nuts. Utilizing Faxon's Gunner profile, it blends the durability of a government profile with the weight savings and maneuverability of a pencil profile. The resulting balance shifts weight back toward the shooter to reduce fatigue, complemented by an M4 barrel extension and mid-length gas system compatibility for reliable performance in dynamic shooting environments.
