Rock Island Armory TM22 Rifle Magazine .22 LR 15/rd

The Rock Island Armory TM22 Rifle Magazine .22 LR 15-round capacity is a factory-original magazine engineered for the Rock Island Armory TM22 series of rimfire rifles. This magazine holds 15 rounds of .22 LR ammunition and features a reliable feed geometry optimized for consistent chambering across diverse ammunition brands and bullet profiles common in .22 LR production lots.

The 15-round capacity provides practical balance between firepower and magazine weight for extended range sessions or field use. The black finish offers standard corrosion resistance and allows discreet operation in tactical training environments. As an original equipment magazine, this unit maintains dimensional tolerances that ensure proper seating in the TM22 magwell without binding or rattle. Magazine springs are calibrated to .22 LR pressure specifications, delivering reliable feeding performance that aftermarket or universal alternatives often cannot match.

The Rock Island Armory TM22 .22 LR magazine serves shooters conducting precision rifle training, competitive rimfire events, and small-game field applications. Serious rimfire marksmen favor OEM magazines for their proven compatibility and elimination of feeding variables during sight-in or qualification work. Having multiple original magazines on hand ensures uninterrupted training cycles and eliminates downtime for magazine troubleshooting—a critical factor in professional and competitive shooting environments where consistency and reliability directly impact performance.

The .22 LR rimfire category remains standard for introductory marksmanship programs, subcaliber training, and low-recoil rifle discipline across law enforcement and military instruction. Factory magazines designed specifically for a rifle model eliminate the guesswork associated with cross-platform magazine sourcing and ensure warranty coverage and manufacturer support.
