The OSS HX-QD 556k is the optimal choice for the those looking for minimal length added to a 5.56 carbine.  Focusing strongly on a minimizing size and weight, the HX-QD 556 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.

Speaking of durability, the HX-QD’s are built with a full auto rating and easily pass the USSOCOM reliability stress test – said differently, these cans are built for abuse. The proven Flow-Through® tech is also focused on the need to not increase back pressure (or blowback) like a traditional baffle stack might. These silencers are tested to impact bolt cycle speed less than 5% over a baseline, therefore muzzle rise and recoil are more easily managed as well as not affecting weapon malfunctions.
