Gemtech's 22 QDA Quick Attach/Detach Adapter makes it easy for you to swap one sound suppressor between different guns in a few seconds. Simply twist the suppressor, slide it off one gun, and twist it on another one - it's that simple! The key to the Gemtech 22 QDA quick attach/detach adapter is a straightforward, two-piece system. The Thread Mount attaches to the barrel, while the QD adapter attaches to the silencer. A simple, four-lug interface enables you to simply twist and detach the silencer/adapter as a unit. We sell extra thread mounts separately, so you can get as many as you need for your other guns. Fits ALL Gemtech rimfire silencers Easy to insta Mfg: Gemtech
