Odin Works AR-10 Barrel Features The Odin Works AR-10 Barrel is built from 416R stainless steel a material chosen for its machinability and corrosion resistance in precision rifle barrels. At 18 inches with a DMR profile the barrel balances weight against the velocity and stability needed for 6mm ARC to perform at distance. Its 1 in 7.5 inch twist rate is matched to stabilize the heavier for caliber bullets favored in long range 6mm ARC loads improving downrange accuracy. The XL rifle length gas system meters gas over a longer dwell time which reduces bolt velocity and the associated wear and felt recoil on every cycle. A .750 tunable gas block ships with the barrel giving the shooter the ability to dial in gas flow precisely whether running suppressed or unsuppressed. The included 6.5 Type II bolt carrier group means the barrel arrives ready to complete a build without sourcing a separate BCG saving both time and compatibility guesswork. The 5/8-24 threaded muzzle accepts a wide range of muzzle devices and suppressors for the 6mm ARC platform. The Odin Works AR-10 Barrel is a complete precision-oriented package for sale at GrabAGun for shooters assembling a serious long range 6mm ARC rifle.
