The GSL Smooth thread protector is perfect to allow the GSL Phoenix or the GSL Scorpion suppressors or any trilug suppressor to securely fasten to the trilug mount while protecting the threads of the weapon. These threads are 1/2×32 (which is pretty uncommon….) make sure you have the right thread pitch selected for your weapon.
