Shaw Barrels Barrel Features The Shaw Barrels Barrel is built as a bull profile replacement for the Ruger 10/22 measuring .920 inches in diameter before spiral fluting removes material to cut weight without sacrificing the rigidity a bull barrel provides. That stiffness helps the barrel resist the heat warping that can affect accuracy during extended range sessions. A 1 to 16 inch twist rate is matched to common .22 LR bullet weights stabilizing them through the full 18 inch barrel length for consistent groups. The Bentz match type chamber is cut tighter than a standard factory chamber improving concentricity and feeding reliability for better overall accuracy. Constructed from 4140 chrome moly steel the barrel is finished with a matte blued coating that resists corrosion while giving it a classic look on a Ruger 10/22 build. A 1/2x28 threaded muzzle cut to a .400 inch thread length accepts standard .22 LR suppressors and muzzle devices without additional gunsmithing. At 2.8 pounds the barrel adds some heft for stability while remaining manageable for plinking or small game hunting. For 10/22 owners chasing tighter groups from a direct drop in barrel the Shaw Barrels Barrel is available for sale at GrabAGun.
