Acheron HexaLug Flash Hider 5.56


Effective flash hider with integrated HexaLug interface. Asymmetric weight reduction cuts eliminate the tuning fork effect and thus the whistling sound typical for open prong flash hiders.

Compatible with all suppressors featuring our HexaLug quick attach mounting system. Due to the one-way compatibility of HexaLug it is possible to install a suppressor of a larger caliber, too. This allows the installation of a 7.62 mm suppressor on a 5.56 mm flash hider.

The use of a flash hider is imperative on all rifles that are also going to be used unsuppressed but can’t show any muzzle flash.

On rifles that are primarily or exclusively used with a suppressor, a muzzle brake may be better suited. The ports of the muzzle brake redirect high-pressure gas towards the side and therefore prolong the life of the suppressor.
