The Resistance(R) 22M is constructed from 7075 T6 Aluminum and features a fully user-serviceable patented HEDP(TM) baffle stack. Trademark Griffin Armament accessory modularity allows for a wide variety of mounting options beyond the included 1/2x28 direct thread adapter. Additional features like a wipe compatible end cap and a 1.375 OD (traditionally seen in pistol silencers) give the Resistance(R) 22M class leading performance across the spectrum of rimfire calibers and even supports a sporting use rating for .223 Remington. The Resistance(R) 22 Modular supports 3-Lug with the use of the Griffin 3-Lug Kit (which is compatible with the Optimus(R) series, Revolution series and Resistance(R) series suppressors). Taper Mounts can also be used with the Taper Mount Minimalist Blast Shield. *Sound reduction ratings are approximate based on measurements by the manufacturer and may vary depending on firearm setup and environmental factors.*
