Claim Text:
1. A firearm discharge gas flow control module fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough, the gas flow control module comprising: an inlet port adjacent a projectile bore defined through a longitudinal center of the module, the inlet port being operable to receive at least a portion of a discharge gas generated by firing the projectile; and a first gas chamber, bounded by the inlet port and at least one wall that at least partially defines a geometry of the gas chamber; the at least one wall of the first gas chamber extending both radially and longitudinally from the inlet port and translating circumferentially as the at least one wall extends longitudinally, such that discharge gas is forced to expand circumferentially as the discharge gas expands longitudinally; wherein the first gas chamber terminates at a circumferential angle of rotation from the inlet port, said circumferential angle of rotation being less than 180 degrees.
