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 1):
A suppressor for a firearm, the suppressor comprising:\n a bullet passage in a conduit that mounts to a muzzle of a barrel of the firearm; an inner shell that forms an inner chamber around the conduit and around a front portion of the barrel when the suppressor is mounted on the muzzle; an outer shell that forms an outer chamber around the inner chamber, each said chamber comprising a front end and a back end; a transverse stationary sound reflector at the front and back end of each said chamber providing opposed sound reflectors in each chamber; a line of sight between the front and back sound reflectors of each said chamber, wherein each chamber is unreduced in cross sectional area between the opposed reflectors thereof in a flow direction therein, minimizing delay of a propellant gas flow through the suppressor; no longitudinal line of sight from the back sound reflector of either of said chambers to the atmosphere; and a gas path from the bullet passage through sides of the conduit to the inner chamber, thence to the outer chamber, thence through an atmospheric exit at the front end of the outer chamber; wherein the gas path is at least 6 times less flow-restrictive than the front end of the bullet passage.
