Ruger factory magazines for the 10/22, Mark series, and PC Carbine are stocked here for rimfire and PCC competitors running Ruger platforms in steel challenge, rimfire division matches, and pistol-caliber carbine stages. The 10/22's rotary magazine and aftermarket BX-25-pattern extended options give rimfire shooters the capacity and reliability needed for fast-paced steel challenge and rimfire PCC stages, while Mark series magazines support Ruger's competition-proven .22LR pistol platform used in bullseye and rimfire steel matches. PC Carbine magazines bring Ruger's pistol-caliber carbine into PCC division competition, with factory-spec capacity and feed lip geometry built specifically for the platform's blowback action rather than adapted from a Ruger pistol magazine. These factory magazines deliver the reliability rimfire and PCC shooters need when a single malfunction can end a stage, with consistent feeding across high-volume practice sessions and cold, dry match-day conditions. Whether you're building out a rimfire steel challenge gun or running a PC Carbine for PCC, factory Ruger magazines are the baseline every serious competitor stocks multiples of.
