- The Ruger 10/22 is a semi-automatic rimfire rifle chambered in .22 LR, featuring an 18.50" cold hammer forged alloy steel barrel in satin black, a 10-round BX rotary magazine, and a checkered walnut stock that brings classic wood stock styling to the upgraded 10/22 platform. A BX-Trigger with a 2.5 to 3 lb pull, match bolt release, integrated rear cleaning port, and combination scope base adapter for Weaver-style and .22 tip-off mounts deliver the enhanced features of the modern 10/22 family in a traditionally styled rimfire rifle built on America's most popular rimfire platform.
