Faxon Firearms AR15 Barrel Features The Faxon Firearms AR15 Barrel in 350 Legend uses the Gunner profile which combines the durability of the Government contour with the weight savings of the Pencil contour bringing the rifle s balance back toward the shooter s body to limit fatigue during long days of training or hunting. Manufactured from 4150 CMV steel the barrel is button rifled with a 1:16 twist rate matched to the 350 Legend s SAAMI specification for consistent stabilization of straight wall cartridge projectiles. A carbine length gas system cycles the action reliably while keeping the barrel s overall profile compact for maneuverability. An 11-degree target crown protects the rifling at the muzzle and helps ensure consistent accuracy shot after shot. Every Faxon barrel is magnetic particle inspected and individually checked for headspace using precision PTG gauges catching hidden defects before the barrel ever reaches a rifle build. The barrel is finished in a durable nitride coating both inside and out for corrosion resistance and smoother function and a 1/2x28 threaded muzzle accepts a wide range of muzzle devices. Manufactured in-house in Cincinnati Ohio from certified 4150 Mil-Spec steel Faxon barrels are built and air-gauge tested for superior accuracy.
