Gemtech was at the American Suppressor Association Media Day here at the NRA Annual Meeting 2017.
They have a new accessory for rimfire suppressors. It is called the 22QDA. It is a universal quick detach mounting system. It uses a quad lug adapter that you screw onto any 1/2×28 rimfire threaded barrel. The quad lug mount is also threaded 1/2×28 and screws onto the back of your preferred rimfire suppressor, turning your can into a QD can.
You can see in the photo above that it uses a proprietary quad lug design. The pattern is actually keyed. If you look at the very top photo you can see a small machined mark on the quad lug adapter and mount. You align those marks and then twist the can on.

One of the cooler things I saw at the @americansuppressor shoot here at @nraam2017 @gemtechsilencer has a universal quick detach for #rimfire it is called the #22QDA it is threaded 1/2×28. I'm not sure if it will handle a 9mm but I will go ask them tmw. #quadlug #suppresseverything
The 22QDA retails for $129.99 and comes with one quad lug adapter. You can purchase more adapters for $30.
This system is only rated for .22LR and .22WMR. Even though there are other caliber barrels with 1/2×28 thread pitch don’t use this on them.
