Designed with a laminate Mannlicher stock, the Ruger 10/22 Carbine .22 LR Semiautomatic Rifle boasts a 2-screw V-block system that securely keeps the 18.5-inch cold hammer-forged barrel and aircraft-grade aluminum-alloy receiver together. It has a positive, push-button crossbolt manual safety and a scope-base adapter that fits Weaver-style and .22 tip-off mounts (sold separately).
