SkySoldier 0 Report post Posted August 15, 2017 Assuming the flash arrestor is a screw on/off, does anyone know the muzzle thread count on the Sig Sauer S22 Black Rifle? I'm considering buying a sound suppresor/silencer and the thread count is 1/2" x 28 threads. Any help or recommendations? Quote Share this post Link to post Share on other sites
