HUXWRX Flow 556K Suppressor & Muzzle Brake Kit

HUXWRX, formerly known as OSS Suppressors, released their first consumer 3D printed 5.56 suppressor called the Flow 556K.

An innovation upon the classic OSS Suppressors’ Flow-Through technology: the Flow 556K mitigates gas in your face and reduces back pressure. Made of 17-4 Stainless, the HUXWRX Flow 556K weights just 11.8 oz and measures a scant 5.5 inches, making it easily maneuverable on your host. This suppressor was designed to withstand the rigors of US Government testing. The Flow 556K is full-auto rated for short-barreled weapons.

The Flow 556K has a repeatable, and minimal point of impact shift. With its Torque Lock System, this suppressor tightens with every round fired. 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 FH (Flash Hider) kit includes a flash hider muzzle device, so you’ll be ready to hit the range right out of the box.

The Flow 556K is also versatile: optimized as a 5.56 suppressor it can also shine on other firearms and cartridges outside of 5.56/.223. The Flow 556K is rated for 5.7×28, 17HMR, and other .22 and smaller centerfire rounds. Operate your HUXWRX suppressor confidently, knowing they will repair/replace, at no charge, suppressors made by HUXWRX Safety Co. and OSS Suppressors deemed to have manufacturer defects.

This is a regulated item and requires shipment to a FFL/SOT holder. After you have placed your order, please have your order number and a copy of your preferred store’s FFL/SOT emailed to to avoid delays. After I have received their FFL/SOT, I will file a Form 3. Upon approval, I will ship your order as soon as possible!
