Shaw Barrels Barrel Features The Shaw Barrels Barrel delivers factory contour geometry machined from 4140 chrome moly steel for a drop-in fit on the Ruger 10/22 receiver. The 1:16 twist rate is matched to standard .22 LR bullet weights keeping groups tight across typical rimfire ammunition. A Bentz match type chamber tightens headspace tolerances compared to a standard factory chamber which helps consistency when accuracy matters. At 16.5 inches overall and 1.6 pounds the barrel keeps the rifle s balance close to stock while adding precision upgrades underneath the surface. Finished in a matte blued coating over the chrome moly steel the barrel resists glare in the field and wears well with regular use. The 1/2x28 threaded muzzle cut to a .400 inch thread length is ready to accept a suppressor or muzzle brake right out of the box. Made in the USA the barrel is built to the same standards shooters expect from a dedicated barrel maker rather than a mass production run. Owners replacing a worn or underperforming factory barrel will get a noticeable accuracy gain without altering the rest of their 10/22 build.
