Ruger 10/22 Competition Custom | .22 LR | 16.12 in | 31120

The Ruger 10/22 Competition Custom (MFG# 31120) is a Ruger Custom Shop variant of the iconic 10/22 platform built for improved rimfire accuracy and repeatability. It features an enhanced semi-auto chamber, a cold hammer-forged fluted bull barrel threaded 1/2″-28, and a fully adjustable speckled black/gray laminate stock with an adjustable cheek rest. This configuration is optics-ready on an integral 30 MOA Picatinny rail; a compact, durable optic such as the Vortex Crossfire II 1-4×24 pairs well for short- to mid-range rimfire competition and precision practice without exceeding typical budget limits.

Common uses for this rifle include rimfire competition and precision range training where consistency and an adjustable cheek weld matter.
