A firearm discharge gas flow control module is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The gas flow control module includes an inlet port, operable to receive at least a portion of a discharge gas generated by firing the projectile, and a gas chamber, bounded by at least one wall that at least partially defines a geometry of the gas chamber. The gas chamber extends both radially and longitudinally from the inlet port and translates circumferentially as the gas chamber extends longitudinally. The gas chamber terminates at a circumferential angle of rotation from the inlet port, the circumferential angle of rotation being less than 180 degrees.

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; anda 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; whereinthe first gas chamber terminates at a circumferential angle of rotation from the inlet port, said circumferential angle of rotation being less than 180 degrees. 2. The module of claim 1, further comprising a second inlet port and a second gas chamber extending from the second inlet port, the second gas chamber being circumferentially offset from the first gas chamber. 3. The module of claim 2, wherein the second gas chamber; extends along substantially the same longitudinal space as does the first gas chamber. 4. The module of claim 1, further comprising a plurality of gas chambers, each circumferentially offset from one another, and each extending along substantially the same longitudinal space as one another. 5. The module of claim 4, wherein some of the plurality of gas chambers terminate in an open area in fluid communication with the bore of the module. 6. The module of claim 5, wherein some of the plurality of gas chambers terminate in a location fluidly isolated from the bore of the module. 7. The module of claim 1, wherein the at least one wall translates circumferentially as it extends longitudinally to form an angle of extension of between about 30 degrees and about 75 degrees, relative to a longitudinal axis of the module. 8. The module of claim 7, wherein the angle of extension is about 60 degrees. 9. The module of claim 1, wherein the at least one wall includes a stepped portion extending substantially parallel to a longitudinal axis of the module, the stepped portion increasing an effective overall length of the at least one wall. 10. A firearms suppressor operable to be fluidly coupled to a muzzle end of a firearm, the suppressor comprising: a plurality of discharge gas flow control modules arranged in a longitudinal stack, each of the modules including a plurality of gas chambers arranged in a circumferentially offset orientation, each gas chamber being operable to receive a different portion of a discharge gas generated by firing a projectile; whereineach of the gas chambers is bounded by at least one wall that at least partially defines a geometry of the gas chamber, the at least one wall extending both radially and longitudinally from an inlet port adjacent a bore defined through a longitudinal center of each module 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. 11. The suppressor of claim 10, wherein each gas chamber terminates at a circumferential angle of rotation from its respective inlet port, said circumferential angle of rotation being less than 180 degrees. 12. The suppressor of claim 10, wherein gas chambers of any one module extend along substantially the same longitudinal space as do other gas chambers of said one module. 13. The suppressor of claim 10, wherein some of the plurality of gas chambers of each module terminate in an open area in fluid communication with the bore of the module. 14. The suppressor of claim 13, further comprising an outer cover substantially encasing the modules, and wherein some of the plurality of gas chambers terminate in a location adjacent the outer cover and isolated from the bore of the module. 15. The suppressor of claim 10, wherein the at least one wall that translates circumferentially as it extends longitudinally to form an angle of extension of between about 30 degrees and about 75 degrees, relative to a longitudinal axis of the module. 16. The suppressor of claim 15, wherein the angle of extension is about 60 degrees. 17. A method of controlling gas flow discharged from a firearm, comprising: arranging one or more gas flow control modules on the end of a muzzle of a firearm, each of the one or more modules including at least two gas chambers arranged in a circumferentially offset orientation, wherein each of the gas chambers is bounded by at least one wall that at least partially defines a geometry of the gas chamber, the at least one wall extending both radially and longitudinally from an inlet port adjacent a bore defined through a longitudinal center of each module 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;discharging the firearm to fire a projectile, thereby generating discharge gas, a portion of the discharge gas which is thereby routed through the gas chambers of the modules. 18. The method of claim 17, wherein a gas chamber of any one gas flow control module extends along substantially the same longitudinal space as do other gas chambers of the any one gas flow control module. 19. The method of claim 17, wherein at least one of the at least two gas chambers terminates in an open area in fluid communication with the bore of the module. 20. The method of claim 19, wherein an outer cover substantially encases the one or more modules, and wherein at least one of the at least two chambers terminates in a location adjacent the outer cover and isolated from the bore. 21. The method of claim 17, wherein the at least one wall translates circumferentially as it extends longitudinally to form an angle of extension of between about 30 degrees and about 75 degrees, relative to a longitudinal axis of the module. 22. The method of claim 21, wherein the angle of extension is about 60 degrees.
