Mec-Gar Ruger Mark III & Mark IV 10-Round Magazine – .22 LR
The Mec-Gar Ruger Mark III & Mark IV Magazine (MYMGMK322LRB) is a world-class alternative to factory magazines, offering the same legendary reliability at a more competitive price point. As the world’s leading OEM magazine manufacturer for many of the top firearm brands, Mec-Gar applies their specialized expertise to the Ruger rimfire platform. This 10-round magazine is precision-engineered to provide flawless cycling in both Ruger Mark III and Mark IV pistols, including 22/45 models.
Constructed from heat-treated carbon steel with a friction-reducing blued finish, this magazine is built to withstand tens of thousands of rounds of rimfire carbon and debris. It features a specialized side-loading button that allows the shooter to depress the follower for effortless, thumb-saving loading. The high-tensile music wire spring and self-lubricating polymer follower ensure consistent upward pressure, eliminating the "last round" feeding issues often found in inferior aftermarket magazines. Whether you are a competitive bullseye shooter or a weekend plinker, the Mec-Gar MYMGMK322LRB provides the consistent performance required for Ruger’s most popular .22 LR handguns.
Compatibility Note: This magazine is fully compatible with Ruger Mark III, Mark IV, and 22/45 series pistols. It is not designed for Mark I or Mark II models without baseplate modification.
