An innovative multi-caliber suppressor with patented and proven Flow-Through® and Torque Lock® technology. It is designed to reduce signature without negatively impacting cycling or service life. The FLOW 556k is DMLS printed in 17-4 Stainless. It delivers superior toxic fume exposure mitigation, flash reduction, sound reduction, recoil reduction, accuracy, and repeatability by its unique Flow-Through® helical coil and core deflector design. It is full-auto rated and compatible on 5.56, 17 HMR, and 5.7 platforms. The integrated flash cap geometry effectively mitigates flash as part of its overall signature reduction funtionality.

Compatible with Muzzle Brake-QD 556 and Flash Hider-QD 556.




  • Repeatable and Minimal Shift
    • HUXWRX suppressors are precision engineered with a consistent mounting interface, resulting in repeatable and minimal point of impact (POI) shift that meets worldwide military specifications.


  • Full- Auto Rated Torque Lock System
    • HUXWRX' full-auto rating guarantees the suppressor passes the U.S. SOCOM Reliability Stress Test.


  • Torque Lock System
    • Our patented, tool-less locking system ensures the suppressor stays securely mounted on the HUXWRX QD muzzle device. Exiting gases create a rotational force, keeping the suppressor firmly seated, making it impossible for the suppressor to come loose when shooting. Further, the torque and friction generated when firing effectively seals the suppressor against the muzzle device’s tapered surface, keeping the mounting surfaces and threads clean from carbon buildup. The friction generated by hand tightening the unit firmly seats the suppressor against the tapered surface securing it for transport.
