The Ruger 10/22 rifle is America's favorite 22 LR rifle, and it's ideally suited for informal target shooting, plinking, small game hunting, and action-shooting events. This model features a hammer-forged barrel locked into the receiver by a unique two-screw V-block system, a precision-machined A380 aluminum alloy receiver and a patented detachable rotary magazine with a unique rotor to separate cartridges and provide reliable feeding. It comes with a combination scope base adapter for both Weaver-style and 22 "tip-off" scope mounts.
