HUXWRX Flash Hider-QD 556 | 1/2×28 | MFG# 1677

The HUXWRX Flash Hider-QD 556 (MFG# 1677) is a quick-detach muzzle device engineered to mitigate visible muzzle flash and provide a dedicated mount for select HUXWRX/OSS suppressors. It fits AR-platform barrels with 1/2×28 threads and is intended for use with .223 Rem/5.56 NATO rifles. The device is compatible with several HX-QD and FLOW series suppressors; VENTUM series compatibility requires the HUX HUB Adapter.

Typical applications include range training and competition shooting where reduced flash signature and fast suppressor attachment/detachment are desired, and use on suppressor-equipped precision or tactical-oriented AR builds.
