A flash hider, sometimes called a flash suppressor, is a device attached to the muzzle of a firearm that reduces the visible light generated by the gun when fired. Flash hiders work by scattering the burning gases that create the “flash” of gunfire, thus reducing the amount of light that reaches the shooter’s eye. Most flash hiders also have some effect on muzzle rise, which can be desirable in specific shooting applications.
There are many different designs of flash hiders, but they all share a common goal: to reduce the visibility of gunfire. Some models are more effective than others, but all will help to some extent in hiding the telltale sign of a muzzle-flash in low-light conditions.
