HUXWRX Flow 6K Details

The HUXWRX Flow 6K is the first dedicated 6mm Flow-Through suppressor, and it stretches far beyond 6mm and 6 ARC. One can covers 5.56, .223, .22 LR, .17 HMR, 5.7x28, and 5.45x39 with no barrel length restrictions. Flow-Through internals push gas forward and out instead of back at your face, so finicky hosts run clean without tuning, tinkering, or an adjustable gas block.
