Faxon Firearms Duty Barrel Features The Faxon Firearms Duty barrel s Gunner profile shifts the rifle s balance back toward the shooter s body reducing fatigue during a long hunt or extended training day compared to a heavier Government profile barrel. Built from 4150 Chrome Moly Vanadium steel and button rifled with a 1-16 twist it stabilizes .350 Legend projectiles reliably across the cartridge s typical bullet weight range. Every barrel is fully stress relieved and air gauge tested before an 11 degree target crown is cut into the muzzle a step that helps ensure a true consistent bullet exit for tighter groups. Precision PTG gauges check headspace on every barrel individually a level of quality control that shows in the barrel s accuracy potential. Both the bore and exterior are finished in Salt Bath Nitride giving the barrel strong resistance to corrosion and wear whether it lives in a safe or spends a season in the field. The carbine length gas system and .750 inch gas block journal make this barrel a drop-in fit for standard AR-15 pattern carbine builds chambered in .350 Legend. Muzzle threads of 1/2x28 TPI accept common muzzle devices adding flexibility for hunters who want a brake or suppressor. This barrel suits hunters and big game shooters looking for a lightweight accurate .350 Legend upgrade.
