The FLOW 556k is an innovative multi-caliber suppressor featuring patented Flow-Through and Torque LockA(R) technology, designed to minimize shooter signature without compromising cycling or service life. This cutting-edge suppressor is fully 3D-printed from 17-4 stainless steel and coated with C-series high-temperature Cerakote for exceptional durability and corrosion resistance. The unique Flow-Through design, with its helical coil and core deflector, effectively channels toxic gases forward, significantly reducing exposure to the shooter. This innovative approach, combined with the integrated GeoFlash Cap geometry, delivers superior toxic fume mitigation, flash reduction, sound suppression, recoil reduction, and enhanced accuracy and repeatability. The FLOW 556k is fully auto-rated and compatible with 5.56, 17 HMR, and 5.7 platforms. It is compatible with Muzzle Brake-QD 556 and Flash Hider-QD 556 for seamless integration.
