Utilizing OSS Generation V Flow-Through™ technology, the HELIX™ Line was designed to deliver unmatched signature reduction and modularity for tactical, professional, hunting, and sport shooters.

The latest addition to our HELIX line, the HX 762 is an integrated flush mount system built with titanium, stainless steel and cobalt.  The HX 762 dramatically reduces backpressure, blowback, sound and flash signature, and is full-auto rated.  A self-tightening mounting device – the STS-Muzzle Brake – is included.

With the purchase of additional STS-Muzzle Brakes, the HX 762 can be quickly switched between your guns. Just thread the HX 762 onto the STS-Muzzle Brake, hand tighten and you’re ready to shoot.
