Button-rifled, stainless steel factory barrel fits DPMS LR-308 upper receivers. Heavy profile offers extra rigidity, while longer length increases bullet velocity for greater potential accuracy than standard 20" rifle barrels. 1-10" twist rifling helps stabilize medium to heavy bullets. Recessed crown protects muzzle from dings and scratches. Gas port is drilled for standard rifle-length gas system, and barrel exterior is pre-dimpled for easy gas block installation with .750" diameters. Barrel extension included. Barrel nut available separately.
