ABSTRACT:
A noise suppressor and stabilizer for a firearm having a number of fluidic scillator laminates each having a number of fluidic pressure controlled oscillators disposed thereon stacked and attached to the muzzle end of a firearm. The pressure controlled oscillators exhaust part of the propellant gases at a frequency either above the range of detection by the human ear or at a less sensitive region of hearing thus lowering the characteristic muzzle blast heard as the bullet exits the muzzle of the firearm. Additional laminates having the pressure controlled oscillators asymmetrically placed are provided to compensate for muzzle climb. Twist of the firearm is controlled by the placement of one or more twist compensating laminates within the stack. One embodiment of the invention provides for laminates of different internal dimensions forms expansion chambers within the noise suppressor.
