SIG MOSQUITO M9 x .75 to 1/2-28

This adapter allows your Sig Mosquito or GSG FIREFLY pistol to use standard U.S. 1/2-28 threaded sound suppressors or other muzzle accessories. This adapter replaces the factory barrel nut. The Hughes Precision adapters metric thread now screws on replacing the factory barrel nut thus completing the conversion to 1/2″-28 U.S. standard thread configuration. A machined thread protector with a fluted OD is also included in the price so that you won’t run the risk of damaging the threads when muzzle accessories are not being used.
