Take your build to the next level with the Seekins Precision .308 Winchester Barrel. Machined from match grade 416R stainless steel and 5R rifled, this 18” barrel offers unprecedented accuracy out of your semi-automatic AR-308 platform. It uses a 1:11 twist rate and a rifle length gas system with .750” gas block shelf and is dimpled for easy alignment. The 5/8x24 threaded muzzle accepts any muzzle device you want. The matte ArmorBlak coating reduces glare and helps to further protect it from corrosion for a long barrel life. Each Seekins Precision barrel goes through a rigorous inspection process to ensure nothing but quality leaves their factory floor.
