The HX MAGNUM is an integrated flush mount system built with titanium, stainless steel and cobalt.  Even though the HX MAGNUM was designed for large-bore precision bolt rifles, 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 (5/8×24 TPI) – is included.  This suppressor is “hearing-safe” on select .338 systems.


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.


The Helix HX-.338 Magnum can suppress a typical .338 bolt action rifle down to approximately 128 dB.


Currently, additional OSS STS-Brakes are not available from OSS.  However, with the purchase of a separate STS Flash Hider, the HX Magnum can be quickly switched between your 5.56 or 7.62 guns.   Just thread the HX Magnum onto the STS Flash Hider, hand tighten and you’re ready to shoot.
