A Wflash suppressor, also known as a flash hider, is a device attached to the muzzle of a rifle or other firearm that reduces the visible signature of the burning gases that exit the muzzle, which may also reduce recoil. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy.
"Significantly reduces muzzle flash when firing."
