The Ruger Mark III/IV .22 LR 10-round steel magazine is a factory original component built to handle the demands of serious rimfire shooters. Whether you're running a Mark III or the newer Mark IV platform, this steel-body magazine delivers the same reliable feed and durability you expect from Ruger's manufacturing standards. Ten rounds of .22 LR capacity keeps you on target longer between reloads—ideal for target practice, plinking, small-game hunting, or competitive rimfire events.
Steel construction ensures this magazine withstands repeated loading cycles and field use without flexing or failing. The polymer base plate provides a protective, non-marring foundation and aids in smooth loading and unloading. As a factory Ruger magazine, it's engineered to exact tolerances for your specific platform, eliminating the guesswork of aftermarket compatibility.
If you shoot a Mark III or Mark IV regularly, having a spare or backup magazine isn't just convenient—it's practical. Ruger magazines wear over time with heavy use, and keeping a fresh one on hand means your rifle is always ready to go. Stock up and shoot longer without fumbling with single-round loading or dealing with a worn feed lip.
