"The Gemtech Neutron 7.62 DT Suppressor provides industry-leading sound and blowback reduction with the ideal blend of size, strength, and weight. Made from 17-4 stainless steel and 6AL4V titanium, it's just 6.6"" long and 14.6 ounces overall but it boasts greater wall thickness and durability than anything else in its class. The Neutron Silencer features a tubeless design that helps eliminate unnecessary weight along with a stepped-baffle design that slows down gasses to reduce pressure. Proprietary evacuating blast chambers accelerate the exit of lingering gasses, minimizing blowback and making for a more comfortable shooting experience. The Neutron is full-auto rated for everything from 5.7x28mm to .300 Winchester Magnum. It's HUB-compatible and can be mounted directly to 5/8""-24 threads.
