Factory threaded SIG Mosquito .22 LR pistols need this thread adapter if you want to mount any 1/2x28 TPI threaded accessories such as a suppressor, a flash hider from an AR15 or one of our UNRESTRICTED FAKE SUPPRESSORS, then this is the part that you need. This thread adapter easily replaces the factory thread protector and can easily be installed or removed in seconds with a standard 9/16 open end wrench. The adapter will only work on FACTORY THREADED guns.
The thread adapters are CNC manufactured to precision tolerances in one lathe operation to ensure exact thread alignment. They are hot salt blued to match the finish on your pistol. Each retail packaged adapter assembly consists of one adapter and one knurled OD thread protector. You get BOTH PIECES for ONE LOW PRICE! Order one now!
