Huxwrx Flow 556k

The HUXWRX Flow 556K represents a paradigm shift in suppressor technology with its patented Flow-Through design that virtually eliminates gas blowback while maintaining exceptional at-ear sound suppression. This is the first 3D-printed (DMLS) suppressor available to the civilian market, manufactured from heat-treated 17-4 stainless steel. The Flow 556K won the FBI Hostage Rescue Team suppressor contract, validating its performance in the most demanding applications.

Unlike traditional baffle-stack suppressors, the Flow-Through design directs gas forward and out the muzzle rather than allowing it to escape back through the action. This results in cleaner shooting with virtually no change to ejection pattern or cyclic rate. PEW Science testing found the Flow 556K achieved the highest at-ear Suppression Rating on the MK18 platform, with a Composite Suppression Rating of 33.1, making it unprecedented in their testing.

As an NFA item, the Flow 556K requires ATF Form 4 approval and a $200 tax stamp. At $1,600, it commands a premium price for its advanced technology. The proprietary LH-threaded taper mount system provides secure attachment but limits compatibility with other suppressor ecosystems. For shooters prioritizing gas mitigation and shooter comfort, the Flow 556K is unmatched.
