The HX-QD 556 Ti suppressor – with patented and proven Flow-Through and Torque Lock technology – is built with a combination of Grade 5/Grade 9 Titanium and 17-4 stainless steel. It delivers superior accuracy and repeatability, is full-auto rated, and compatible with 5.56 rifles with no minimum barrel restrictions.

It utilizes OSS’s new Flash Cap that eliminates virtually all flash. And unlike other 556 titanium suppressors, the HX-QD 556 Ti has a stainless-steel core that delivers durability in excess of 40,000 rounds vs. all titanium suppressors that last a fraction of that.

Materials & Finish: Unlike traditional suppressors that trap gas in dead ends, OSS’s Flow-Through technology redirects and controls expanding gases forward through a serpentine path of nested tubes, allowing us to use 17-4 stainless steel deflectors in the core and Grade 5 and Grade 9 Titanium everywhere else. The result is an extremely durable titanium suppressor. The HX-QD 556ti has a fully-welded body coated with C-series high temperature Cerakote.

Sound Pressure Levels: The HX-QD 556 Ti is the optimal choice for the widest range of 5.56 caliber rifles. Sound pressure levels are measured at the shooter’s ear to comply with current military specifications:
