Abstract
A flash hider has a central bore for receiving the barrel of a firearm at one end and three tapered tines at the opposing end with a gap formed between each pair of adjacent tines. Just past the muzzle-seat in the central bore is a flared entrance leading to the gaps thereby allowing hot air and combustion gases to expand radially through the gaps between the tines, thereby cooling the hot air and gases. The lateral faces of the tines are stepped to cause turbulent mixing of the cooler air surrounding the flash hider with the exiting gases so as to further expand and cool in order to prevent re-ignition and thereby reduce secondary flash. Long tines help to hide all but direct viewing of primary flash.
