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 10):
A suppressor for mounting on a barrel of a firearm, the suppressor comprising:\n a conduit that mounts to the barrel and extends forward from a muzzle thereof; a bullet passage in the conduit for a bullet of the firearm to pass from a bore of the barrel through the conduit without contact; the bullet passage comprising an aperture at a front end of the conduit having 5-18% greater diameter than the bore diameter; an inner shell comprising a front end sealed around the front end of the conduit, and a back end that extends around the barrel, forming a continuous inner annular chamber with a first portion around the conduit and a second portion longer than the first portion around a front portion of the barrel when the suppressor is mounted on the barrel; a first gas path through the bullet passage exiting the front end of the conduit; a second gas path through sides of the conduit between the bullet passage and the inner chamber, the second gas path having a flow aperture area at least 6 times greater than a flow aperture area of the bullet passage at the front end of the conduit; an outer annular chamber comprising an outer shell that surrounds the inner shell; a third gas path comprising apertures over 1/10 to \u2153 of a lengthwise proportion of the inner shell and located within a middle half of a length of the inner shell, the third gas path having a flow aperture area at least 6 times greater than the flow aperture area of the bullet passage at the front end of the conduit; a fourth gas path on the front end of the outer shell, venting the outer chamber to the atmosphere, the fourth gas path having a flow aperture area at least 6 times greater than the flow aperture area of the bullet passage at the front end of the conduit; and a sound reflector at front and back ends of both the inner chamber and the outer chamber, providing opposed sound reflectors in each said chamber, a line of sight between the front and back sound reflectors of each chamber, and no longitudinal lines of sight from either of said chambers to the atmosphere; wherein least 70% of an acoustic reflection plane of each reflector in each chamber can be geometrically projected onto the opposed reflector in the same chamber unshaded by intervening suppressor elements.
