Shaw Barrels Bull Barrel Features The Shaw Barrels bull barrel is machined from 416R stainless steel a material favored in precision barrel making for its machinability and corrosion resistance then finished with a polished exterior for a clean custom look on a Ruger 10/22. At 18 inches in length with a 0.920 inch bull diameter the barrel adds mass along its length that helps resist heat-induced stringing during extended range sessions. A 1:16 inch twist rate is matched to standard .22 Long Rifle bullet weights for consistent stabilization and accuracy. This straightforward direct-fit replacement barrel is designed to swap onto a factory 10/22 receiver without requiring extensive gunsmithing. A Bentz match chamber is cut into the barrel a chamber specification known among rimfire shooters for improving feeding reliability and accuracy compared to a standard sporter chamber. At the muzzle an 11 degree target crown protects the rifling s final lands and grooves from damage while promoting even consistent bullet release as each round exits the bore. At 3.1 pounds the barrel s added weight contributes to a more stable hold and reduced muzzle movement during firing compared to a stock factory barrel.
