The Griffin Resistance 22M rimfire suppressor is a modular .22 caliber can that packs more internal volume than most rimfire suppressors into a light, configurable package (Griffin Armament part no. GARS22-W). Griffin builds the tube and end cap from 7075-T6 aluminum and fills it with a patented HEDP baffle stack that the owner can take apart and clean. A 1/2×28 direct thread mount comes in the box, and Griffin’s accessory modularity opens up other mounting options beyond it. It is made for the rimfire rifle or pistol that sees the most range time and the most cleaning.

Frequently Asked Questions
