  • Product Description

    HUXWRX released its first 3D-printed 5.56 suppressor, the FLOW 556K. An innovation upon the classic Flow-Through™ technology, the FLOW 556K mitigates gas in your face, reduces back pressure, and offers impressive sound reduction. Shooting suppressed with the FLOW 556 means you’ll have more time to shoot and less time tuning your rifle. 


    Made of  3D-printed 17-4 stainless steel, the HUXWRX FLOW 556K weighs just 11.8 oz and measures a scant 5.5 inches, making it easily maneuverable on your host. HUXWRX created this can to withstand the rigors of US Government testing: the DLMS printed, 17-4 stainless steel construction has achieved a full auto rating that will withstand intense shooting, even on short-barreled platforms.


    With the FLOW 556K on your rifle, you'll have a minimal point of impact shift with the engineered helical cores, cones, and the patented Torque Lock Mounting System. Using left-hand threads, this 556 caliber suppressor will tighten with every shot, ensuring it will never come loose while shooting. The Torque Lock System aligns using a taper and the Flow-Through™ technology helps seal the can against the QD mounting surface: meaning no carbon will get into the threads. The HUXWRX FLOW 556K includes a flash hider muzzle device, so you’ll be ready to hit the range right out of the box.
