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®.
Sound Pressure Levels: The HX-QD 556 is the optimal choice for the widest range of 5.56 caliber rifles. Sound pressure levels are measured at the shooters ear to comply with current military specifications:
• 130 – 134 dB on 20” AR15 DI using commercial grade 55 gr ammo
• 133 – 137 dB on 16” AR15 DI using commercial grade 55 gr ammo
• 138 – 142 dB on 10.5” AR15 DI using commercial grade 55 gr ammo
