Abstract:
A conduit ( 5 ) with a bullet passage ( 13, 17 ) extends forward from a gun muzzle ( 7 ). Inner and outer concentric chambers ( 25, 29 ) surround the conduit and a forward portion of the barrel ( 3 ). A gas path (P 2,  P 3,  P 4 ) is provided through sides of the conduit into the inner chamber, thence to the outer chamber, and then exits to the atmosphere at the front of the outer chamber. Each chamber has longitudinal lines of sight between front and back sound reflectors (R 1 -R 2,  R 3 -R 4 ), and no longitudinal line of sight from the back reflector (R 2,  R 4 ) to the atmosphere. The gas path through the suppressor is at least 6 times less flow-restrictive than the gas path through the bullet exit ( 17 ) or back into the barrel bore ( 4 ), minimizing backpressure. The gas path (P 3 ) between the inner and outer chambers is through apertures ( 33 ) limited to a lengthwise middle portion of an inner shell ( 21 ) that divides the chambers ( 25, 29 ).

Claim (Index 12):
The suppressor of  claim 10 , wherein the sound reflector at the front end of the outer chamber comprises first and second transverse aperture plates, each aperture plate comprising a respective plurality of apertures, the apertures of the first aperture plate being offset from any longitudinal line of sight through the apertures of the second aperture plate;\n and a gas flow space between the plates, wherein the fourth gas flow path passes through and between the transverse aperture plates.
