Shaw Barrels Barrel Features The Shaw Barrels Barrel is machined from 4140 chrome-moly steel and finished in a durable Matte Blue coating that resists corrosion through regular range use. Its .920 inch bull barrel diameter adds mass and rigidity compared to the factory Ruger 10/22 barrel which helps reduce barrel whip and improve shot-to-shot consistency. A Bentz match-type chamber is cut for tighter tolerances than a standard sporter chamber contributing to improved accuracy with quality .22 LR ammunition. The 1:16 twist rate matches the stabilization needs of standard-weight .22 LR bullets. An 11 degree target crown protects the rifling at the muzzle from dings and uneven wear helping preserve consistent accuracy over the life of the barrel. At 18 inches and 3.1 lbs the barrel adds some weight over a factory lightweight barrel which many shooters find improves offhand steadiness for target work. This barrel is made in the USA and built as a direct replacement for the Ruger 10/22 platform so installation follows the same process as a factory barrel swap. For 10/22 owners chasing tighter groups the Shaw Barrels Barrel offers a proven accuracy upgrade.
