Gemtech 22QDA – 4 Lug Rimfire Adapter

    Traditionally, mounting a suppressor to a rimfire host involves screw threads rather than the quick detach methods found on many modern-day rifle suppressors. And the H&K style 3-Lug silencer mounts have been reserved for subguns and pistol caliber carbines. Hoping to change the way (and speed) in which we swap 22 long rifle cans across hosts, Gemtech has released the 22QDA – a four lug, spring loaded mounting system capable of being used on any 1/2 x 28″ rimfire silencer.

    The principle is fairly simple: First, attach the 1/2″ x 28 to four lug mount adapter to your favorite rimfire silencer. Second, attach the four lug muzzle device to your favorite host(s). Then use the push, turn release method to attach and detach your the suppressor.

    “But I don’t mind my current thread mount.” True, direct thread silencers do have their benefits. But the QD22A system solves a few issues that can plague rimfire shooters. First, direct thread silencers have a tendency to unscrew/disassemble the thread mount from the silencer during the removal process.

    Second, a popular setup for suppressed rimfire AR15s is to mount the silencer under a rail system for a more compact package. The four lug Gemtech system will allow for quick and easy attachment and removal of recessed cans.

    And lastly, we all have our favorites: using the 22QDA mount with additional four lug muzzle devices, shooters can swap their primary rimfire silencer quickly between hosts. Also, one side benefit of Gemtech’s new system is that the muzzle device isn’t much longer than a standard threaded barrel.

    Why four lugs and not the standard three? My guess is to avoid the eventual tragedy of someone mounting the 22QDA on a non rimfire can and host. Come on, we all know ‘that guy’.

    MSRP for the full kit is $129.99 whereas additional muzzle devices will start at $32.99 each.

    I really appreaciate the way Gemtech innovates and takes risks to bring new products to market. Last summer we stumbled across an interesting patent issued to Gemtech for a ‘Quick Connect for a Pistol Suppressor that appears to incorporate a booster module along with a QD system:
