OSS HX-QD 556K Kit

Focusing strongly on a minimizing size and weight, the OSS HX-QD 556K Kit is ideal for shooters who are more concerned with maneuverability over maximizing sound performance. As with all of the OSS Helix style silencers, the patented Flow-Through technology of this silencer redirects the expanding gasses in a helical pattern allowing the gas to expand and cool as they move through the silencer body. This unique design also means that the expanding gas generate torque on the silencer and snugging it onto the mount. As the gas moves through the 17-4 stainless and Grade 5 titanium coils, the resulting effect on the silencer tube is a remarkably cooler and extremely durable suppressor. The HX-QD’s are built with a full auto rating and easily pass the USSOCOM reliability stress test. The proven Flow-Through tech is also focused on the need to not increase back pressure (or blowback) like a traditional baffle stack might. The OSS HX-QD 556K Kit comes with a short compact silencer and an OSS flash hider mount that is a 1/2×28 thread pitch.
