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 22):
A firearm flash suppressor, comprising:\n an inner tube including a passage configured to allow a bullet to travel through the flash suppressor; an outer tube configured to at least partially surround the inner tube and to form a burn chamber between the inner tube and the outer tube; a base cap attached to the outer tube and configured to attach the flash suppressor to at least one of a firearm muzzle, a flash hider, or a muzzle brake; and an end cap attached to the outer tube and the inner tube, wherein, the inner tube is configured to seat securely against the at least one of a firearm muzzle, a flash hider, or a muzzle brake, and to fixedly align center axes of the passage and the at least one of a firearm muzzle, a flash hider, or a muzzle brake, and wherein, the passage of the inner tube has a substantially uniform cross-section, and a thickness of the inner tube changes over a length of the burn chamber to change a cross-sectional area of the burn chamber.
