A short and extremely durable suppressor, the HX-QD 556k – updated with the newly designed flash cap – is built with patented and proven 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.
Unlike traditional suppressors that manage trapped gas, intense heat and pressure with blast baffles, OSS Flow-Through® technology redirects expanding gases forward allowing the use of 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®.
