The Gemtech Neutron 7.62 suppressor with a 5/8×24 direct thread mount balances size, strength and weight for .30-caliber rifles (brand part no. 14178). Gemtech describes it as suited to everything from a short-barreled machine gun to a favorite hunting rifle, and it accepts a wide range of mounting hardware for different hosts. Its thick tubeless design sheds needless weight, and the refined baffle and end cap help cut muzzle signature. The body is 17-4PH stainless steel and 6Al4V titanium under a high-temp Cerakote finish.
