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 fo Mfg: Operators Suppressor Systems
