"The Gemtech ABYSS 7.62 DT Suppressor represents the next generation of hard-use silencers, reducing muzzle flash and noise while also limiting gas blowback. Made from 17-4 stainless steel and 6AL4V titanium, it's just 6.8"" long and 16.2 ounces overall, but it boasts greater wall thickness and durability than anything else in its class. It's full-auto rated for everything from 5.7x28mm to .300 Winchester Magnum, even with short barrels. And by routing gasses forward, it reduces back-pressure for greater reliability and shooter comfort. The GM-S1 end cap design minimizes muzzle flash from the first shot to the last. It mounts easily using a direct-thread standard, and it comes with everything you need for installation. Includes 5/8""-24 flash hider, ETM adapter, shim set, and tools.
