Shaw Barrels Barrel Features The Shaw Barrels Barrel is machined in an HBAR profile from 416R stainless steel a material known for excellent corrosion resistance and consistent accuracy over repeated firing. A 1 to 12 inch twist rate is matched to common .204 Ruger bullet weights stabilizing them through the 22 inch rifle length barrel for flat trajectories at varmint and predator distances. Straight fluting along the barrel removes weight while preserving rigidity helping manage heat buildup during extended strings on prairie dogs or coyotes. A .750 inch gas block diameter with a dimpled gas journal ensures the gas block sits securely in place under recoil. An M4 feed ramp extension is cut into the chamber area to improve feeding reliability on AR-15 pattern upper receivers reducing the chance of malfunctions during rapid fire. The barrel is finished in a bead blast matte coating that resists glare in the field while standing up to scratches and wear. A 1/2x28 threaded muzzle accepts standard muzzle devices or suppressors for additional recoil and noise control. For AR-15 builders chasing flat shooting .204 Ruger performance with a durable stainless barrel the Shaw Barrels Barrel is available for sale at GrabAGun.
