THE ULTIMATE 5.56 SUPPRESSOR
Proven reiliability and durability, zero flash performance, and hearing safe sound levels
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 556 has a fully-welded outer body made of 17-4 heat treated stainless steel coated with C-series high temperature black Cerakote®.
