This AAC Thread Adapter for the Sig Sauer Mosquito screws directly onto a Sig Factory Threaded Barrel with M9x.75" Thread Pitch, converting it to the more common 1/2"-28 Thread Pitch and making it fully compatible with the wide selection of available sound suppressors, flash hiders and/or compensators equipped with this popular thread pattern. The steel adapter is Parkerized for corrosion resistance and comes complete with a 1/2"-28 Thread Protector for use when a muzzle device is not installed.
NOTE: Installation of this thread adapter is possible only if the host Mosquito Pistol has a Sig Factory Threaded Barrel.
