HX 556


The HELIX 556 (HX 556 ) is an integrated flush mount system built with titanium, stainless steel and cobalt.  The HX 556 dramatically reduces backpressure, blowback, sound, flash signature, and was designed for professional use including full-auto rated (NOT sustained full-auto fire).  A self-tightening mounting device, the STS-Muzzle Brake (1/2 x 28 TPI), is included with each suppressor.


Currently, additional OSS STS-Brakes are not available from OSS. However, with the purchase of a separate STS Flash Hider, the HX 556 can be quickly switched between your 5.56 guns. Just thread the HX 556 onto the STS Flash Hider, hand tighten and you’re ready to shoot.
