Ruger's 10/22 Carbine's legendary action, is a tried and true Ruger design, and ensures consistent, reliable performance. Its cold hammer-forged barrel is locked into the receiver by a unique, two-screw, V-block system. The easy-to-use extended magazine release provides smooth, no-fuss removal of flush-mounted magazine. The 10/22 Carbine also utilizes a cross-bolt safety, polymer trigger housing assembly, detachable rotary magazine and includes a combination scope base adapter for both Weaver-style and .22 tip-off scope mounts.
