The OSS Helix 762 suppressor utilizes a unique 'flow-through' design, significantly reducing back pressure and gas in the shooter's face, making it ideal for semi-automatic rifles. Tested against the Dead Air Sandman-L, the Helix demonstrated superior hearing protection at the ear (138.2 dB vs. 148.6 dB), even while achieving a comparable muzzle reading. Accuracy remained unaffected, with tight groupings at 100 yards and successful hits at 500 yards.
