Ruger’s 10/22 Carbine has a patented, detachable 10-round rotary magazine with a unique rotor to separate cartridges and provide reliable feeding, along with an extended magazine release for smooth, no-fuss removal. Its legendary action ensures consistent, reliable performance; and the heat-stabilized, glass-filled, polymer trigger housing assembly is precision made of high-tech material for improved manufacturing tolerances, impact and abrasion-resistance, and an unmatched ability to withstand the elements. It includes a combination scope base adapter for both Weaver-style and .22 tip-off scope mounts.
