Flash hider with gas flow control modules and associated methods

摘要

A firearm flash hider can include a base module and at least one vented flash control module. The base module can have a longitudinal boreline which is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough. The base module can also have an inlet port which is operable to receive at least a portion of a flash generated by firing the projectile. The vented flash control module can be arranged along the longitudinal boreline distal to the muzzle end. The vented flash control module can also have a flash chamber bounded by at least one wall that at least partially defines a geometry of the flash chamber and extends both radially and longitudinally from the boreline and translates circumferentially as it extends longitudinally. The flash chamber terminates at a circumferential angle of rotation from the inlet port where the circumferential angle of rotation being less than 180 degrees. The flash hider can typically have from one to four vented flash control modules oriented in series.

1. A firearm flash hider comprising:
a base module having a longitudinal boreline which is fluidly coupleable to a muzzle end of a firearm to allow a projectile to pass therethrough; and at least one vented flash control module arranged along the longitudinal boreline distal to the muzzle end, wherein the at least one vented flash control module has an inlet port adjacent a bore along the boreline operable to receive at least a portion of a flash generated by firing the projectile, and a flash chamber bounded by the inlet port and at least one wall that at least partially defines a geometry of the flash chamber, the at least one wall extending both radially and longitudinally from the inlet port and translating circumferentially as it extends longitudinally, wherein the flash chamber terminates at a circumferential angle of rotation from the inlet port, said circumferential angle of rotation being less than 180 degrees.
