A short and extremely durable suppressor, the HX-QD 556k – updated with our newly designed flash cap – is built with patented and proven OSS Flow-Through® technology, delivers sub-140 dB and zero flash performance, is full-auto rated, easily passes the USSOCOM Reliability Stress Test, and has no minimum barrel restrictions – it’s designed and built for extreme use.
Compatible with Muzzle Brake-QD 556 and Flash Hider-QD 556.
Materials & Finish: Unlike traditional suppressors that manage trapped gas, intense heat and pressure with blast baffles, OSS Flow-Through® technology redirects expanding gases forward allowing us to use 17-4 stainless steel deflectors and internal Grade 5 Titanium coils. The result is a remarkably cooler and extremely durable suppressor. The HX-QD 556k has a fully-welded outer body made of 17-4 heat treated stainless steel coated with C-series high temperature black Cerakote®.
Sound Pressure Levels: The HX-QD 556k was designed with minimal length in mind. The low volume and light weight make this suppressor ideal for shooters more concerned with size than maximum sound reduction. Sound pressure levels are measured at the shooters ear to comply with current military specifications:
136 – 140 dB on 20” AR15 DI using commercial grade 55 gr ammo
138 – 142 dB on 16” AR15 DI using commercial grade 55 gr ammo
142 – 146 dB on 10.5” AR15 DI using commercial grade 55 gr ammo
HUXWRX Torque Lock is a patented, tool-less locking system that ensures the suppressor will stay securely mounted onto the HUXWRX QD muzzle device.
The HUXWRX Test Rifles shall not exceed 140 dB ten shot average sound pressure level at shooter’s ear during barrel life.
HUXWRX suppressors full-auto rating guarantees the suppressor passes the USSOCOM Reliability Stress Test.
HUXWRX QD suppressors can be used on a variety of calibers and rifle platforms.
HUXWRX Suppressors are engineered and tested to meet the highest military accuracy specifications worldwide.
REPEATABLE & MINIMAL SHIFT
HUXWRX Suppressors are engineered so that the mounting interface is precise and consistent. The result is repeatable and minimal point of impact (POI) shift that meets military specifications worldwide.
NO WEAPONS MODS
Modifications to the bolt, gas tube, buffer or recoil springs, and other timing modifications are unnecessary.
Bolt velocity increases vary between -2% to 5% depending on weapon system, barrel length, and ammo types.
Suppressor maintenance can be performed to increase the service life of the suppressor.
