The HELIX 7.62 IFM suppressors are an integrated flush mount system that regulates backpressure and reduces sound and flash signature in a single unit while offering greater modularity for use on multiple rifles. Built with titanium, stainless steel, aluminum and cobalt, the HELIX 7.62 IFM suppressors delivers effective strength to weight. The IFM6 and IFM7 also include a separate mounting device – the STS-Muzzle Brake. Built with the same technology used in our ELITE line, the IFM6 delivers hearing safe sound and flash suppression and hassle-free use without the toxic blowback, high heat, or constant need to adjust and clean your gun found with baffle suppressors. And with the purchase of additional STS-Muzzle Brakes in various calibers and thread patterns, the IFM6 can be quickly switched between your guns. Just thread the IFM6 onto the STS-Muzzle Brake, hand tighten and you’re ready to shoot. The self-tightening design of the STS and the IFM6 make them impossible to loosen during fire.
