OSS

An extremely rugged suppressor, the HX-QD® 556 – updated with our newly designed flash cap – is built with patented and proven Flow-Through® technology, delivers hearing safe mid-130s dB and zero flash performance, is full-auto rated, easily passes the USSOCOM Reliability Stress Test, and has no minimum barrel restrictions – it’s the ideal suppressor for all 5.56 rifles. 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’s 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 556 has a fully-welded outer body made of 17-4 heat treated stainless steel coated with C-series high temperature black Cerakote®. ALL NFA RULES APPLY
