The Griffin Resistance 22M is a modular rimfire suppressor that packs more internal volume than most rimfire cans into a light, configurable package (brand part no. GARS22-W). Griffin Armament builds the tube and end cap from 7075-T6 aluminum and fills it with a fully user-serviceable, patented HEDP baffle stack. A 1/2×28 direct thread mount comes in the box, and Griffin’s accessory modularity opens up other mounting options beyond it. Rimfire shooters get coverage for .17 through .22 calibers plus 5.7mm, and Griffin adds a .223 Remington rating with restrictions. It is built for the rifle or pistol that sees the most range time and the most cleaning.

Key Specifications

• The caliber rating is .17 to .22 rimfire and 5.7mm, including .22 LR, .22 WMR and .17 HMR.
• Griffin also rates it for .223 Remington on a 16-inch or longer barrel when used with the Taper Mount Blast Shield Extension.
• Overall length is 4.75 inches, short for a modular rimfire can.
• Weight is 4.9 ounces, light enough for a rimfire pistol.
• Diameter is 1.375 inches, which buys extra internal volume over a slim rimfire tube.
• The tube body and end cap are 7075-T6 aluminum.
• Inside are five HEDP baffles, and the whole stack is user serviceable.
• A 1/2×28 direct thread mount is included, the most common rimfire muzzle thread.
• A neoprene wipe with spacer, a Revolution wrench and a 2-inch fender washer also ship with it.
• Griffin publishes 113 dB on .22 LR pistols, and lists the can as not full-auto rated.
