The HUXWRX Flow 556K is a short, flow-through 5.56 suppressor in FDE. HUXWRX's patented flow-through design sends gas forward and out of the can instead of back into your action, so you get far less gas in your face, a cleaner rifle and less change in how the gun cycles. At just 5.5" it's a great match for SBRs and short-barreled ARs, where traditional cans blow the most gas back at you.
Why it stands out
- Flow-through: much less gas in your face
- Short: 5.5" for SBRs and carbines
- 3D-printed 17-4 stainless with Torque Lock
- QD 556 flash hider (1/2x28) included
- Also rated for 5.7x28, .17 HMR and other .22 and smaller centerfire
