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 18):
A suppressor for mounting on a barrel of a firearm, the suppressor comprising:\n a conduit comprising a back end that threads onto the muzzle of the barrel, a middle portion extending forward of the muzzle, and a bullet passage admitting the bullet from the muzzle to a bullet exit hole at a front end of the conduit; an inner shell attached to and sealed around the front end of the conduit, extending over and behind the muzzle to surround a front portion of the barrel, forming an inner chamber around the conduit and the front portion of the barrel; an outer shell attached to a front end of the inner shell, surrounding the inner shell, and forming an outer chamber between the inner and outer shells; a gas flow path between the bullet passage and the inner chamber, thence to the outer chamber, thence from a front end of the outer chamber to the atmosphere, the gas flow path having a flow aperture area at a most flow-restricted barrier thereof at least 6 times greater than a flow aperture area of a front end of the bullet passage; the gas flow path comprising apertures in the inner shell that admit the gas flow path between the inner and outer chambers only over  1 / 10  to  1 / 3  of an intermediate lengthwise portion of the inner shell within a middle half of a length of the inner shell; and the front end of the outer chamber comprising a sound reflector that admits the gas flow path therethrough without admitting any longitudinal line of sight between the outer chamber and the atmosphere; wherein each said chamber maintains at least 70% of a cross sectional area of the chamber between front and back ends thereof.
