Shaw Barrels Barrel Features The Shaw Barrels barrel is machined from 416R stainless steel and finished with a polished surface giving it both corrosion resistance and a refined appearance compared to a standard factory barrel. Built as a direct bull barrel replacement for the Ruger 10/22 the barrel measures 18 inches long with a .920 inch diameter that adds stiffness and reduces barrel whip during firing. A Bentz match type chamber is cut for tighter tolerances than a standard chamber contributing to improved accuracy with quality .22 LR ammunition. The 1:16 twist rate matches standard .22 LR bullet weights for stable consistent flight. At the muzzle the barrel is threaded 1/2x28 with a .400 inch thread length allowing the installation of a suppressor or muzzle device for shooters who want added versatility. Weighing 3.1 pounds the heavier bull profile helps the barrel resist heat buildup during extended range sessions and contributes to its accuracy potential. The barrel is proudly made in the USA reflecting Shaw s reputation for precision rifle barrel manufacturing. For a Ruger 10/22 owner looking to upgrade accuracy and add suppressor compatibility this Shaw Barrels bull barrel is a direct fit option available for sale at GrabAGun.
