Suppressors from Gemtech are found on a wide variety of military and law-enforcement pistols, rifles, and assault weapons in the US and abroad. The firm's SP-90, designed for FN Herstal's 5.7x28mm-firing P-90 assault weapon, is available directly from FN Manufacturing, Inc., the Belgian company's US subsidiary. An S-FN57, for the company's FiveseveN pistol, will be available soon.
