Utilizing OSS Gen 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 MAGNUM is an integrated flush mount system built with titanium, stainless steel and cobalt.  The HX MAGNUM performs for a wide range of calibers and platforms. From 5.56 up to .338, and for hard to suppress platforms like AKs, M1A/M14s and Galils, the HX MAGNUM “does it all.”  A self-tightening mounting device – the STS-Muzzle Brake – is included.

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