Built to OEM tolerances, this magazine provides reliable feeding for both standard TM22 and A-18 model variants.

Armscor constructed this magazine from high-strength polymer that resists impact damage and corrosion better than traditional steel alternatives.

The black matte finish reduces glare and maintains a clean appearance through regular use. Feed lips and follower geometry are manufactured to Armscor specifications, ensuring consistent cartridge presentation to the chamber. This attention to factory tolerances means the magazine drops free cleanly and locks in place without the fitting issues that sometimes plague third-party options. For shooters who stock their magazines from factory sources, this Armscor unit maintains the reliability standard expected from OEM components.
This TM22 magazine suits shooters running their Rock Island rimfire rifles for small game, pest control, or informal target work where 25 rounds of .22 LR provides adequate capacity without excessive bulk. The lightweight polymer construction adds minimal weight to your range bag compared to steel alternatives. Backed by Armscor's Limited Lifetime Warranty for intended use, this magazine represents a straightforward investment in maintaining your TM22 platform.
