- The Ruger 10/22 is a semi-automatic rimfire rifle chambered in .22 LR, featuring a 16.40" cold hammer forged alloy steel barrel threaded 1/2x28 in satin black, a 10-round BX rotary magazine, and a birch stock that delivers classic wood stock appeal on the upgraded 10/22 platform in a compact, suppressor-ready configuration. 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 bring the full suite of modern 10/22 upgrades to a traditionally styled, threaded rimfire rifle built on America's most popular rimfire platform.
