Acheron HexaLug Flash Hider 5.56mm - 1/2-28 UNEF

Effective flash hider with integrated HexaLug interface. The asymmetrical cutouts on the forks eliminate the tuning fork effect and thus the typical whistling sound of flash hiders with open forks.

Compatible with all silencers with HexaLug interface. The backwards compatibility of HexaLug also allows the installation of a silencer with a larger caliber. For example, an ACS E1 with a caliber of 7.62 mm can be mounted on a fire suppressor with a caliber of 5.56 mm.

For weapons that are used without a silencer and are not intended to have a muzzle flash, a fire suppressor is essential. However, if a weapon is used primarily or exclusively with a silencer, a muzzle brake should be preferred over a flash hider. The three chambers of the muzzle brake divert hot powder gases to the side, which extends the service life of the silencer.
