Abstract:
Flash suppressors having at least one contracting and then expanding burn chamber are described. The contracting and then expanding burn chamber may include one or more ribbed surfaces that enhance burning of propellant gasses and ambient oxygen before the gasses exit the flash suppressor. In some examples, a burn chamber may include a spirally threaded inner and/or outer surface, which swirls and cools the propellant gasses to enhance burning before the propellant gasses exit from the flash suppressor.

Claim (Index 1):
A firearm flash suppressor, comprising:\n a proximal end configured to attach the flash suppressor to at least one of a firearm muzzle, a flash hider, or a muzzle brake; a distal end comprising a first opening for allowing a bullet to exit the flash suppressor and a second opening for allowing gas to exit the flash suppressor; an inner tube disposed between the proximal end and the distal end, and including a passage configured to allow the bullet to travel through the flash suppressor; and an outer tube disposed between the proximal end and the distal end, and at least partially surrounding the inner tube, wherein, an outer surface of the inner tube and an inner surface of the outer tube at least partially define a burn chamber configured to allow burning of a gas exiting from the at least one of a firearm muzzle, a flash hider, or a muzzle brake, and wherein, at least one of the outer surface of the inner tube or the inner surface of the outer tube includes a contour that changes a cross-sectional area of the burn chamber.
