Abstract
A flash suppressor for use with a firearm includes a generally cylindrically shaped housing having a series of horizontal groves about its exterior. An internal thread located at the proximal end of the housing is present for threadedly securing the housing to the muzzle of a firearm. There is a tapered chamber located between the internal threads and the opening which precedes the expansion chamber of the flash suppressor. The expansion chamber progressively expands being smallest at the proximal end and gradually increasing in diameter towards the distil end. Longitudinally extending, progressively helically shaped perforations are formed through the housing and in communication with the internal expansion chamber. These perforations are generally equally distributed about the housing except the bottom area which has no perforations present.
