The FLOW series features Huxwrx's proven Flow-Through technology that offers superior sound suppression while simultaneously directing most of the gas forward to greatly reduce toxic fume exposure. Superior flash mitigation is also ensured with the inclusion of Huxwrx's integrated GeoFlash endcap and is paired with the company's Torque Lock technology that utilizes the gas pressure as a self-tightening mechanism to ensure solid lock up between the suppressor and the barrel. The 556K series is designed for .17 HMR, 5.56 and 5.7mm platforms and features a reduced length for a shorter overall profile. It is compatible with Huxwrx's Muzzle Brake-OD 556 and Flash Hider-QD 556 muzzle devices. This model features an FDE color pattern. No mount is included and must be purchased separately. *Sound reduction ratings are approximate based on measurements by the manufacturer and may vary depending on firearm setup and environmental factors.*
