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 20):
The suppressor of  claim 18  provided as a modular assembly comprising the following parts:\n a) a back plate closing a back end of the outer shell except for a central opening in the back plate to receive the barrel of the firearm; \n b) a transverse ring comprising gas path apertures affixed to or integral with the inner shell and disposed proximate and behind a front rim of the inner shell; \n c) a front plate sealing the inner and outer shells around the front end of the conduit, the front plate comprising exit apertures for the gas path from the outer chamber to the atmosphere; and \n d) the gas exit apertures of the front plate being offset from the gas path apertures in the transverse ring, eliminating any longitudinal line of sight between the outer chamber and the atmosphere; \n e) wherein the conduit further comprises a back end with internal threads for engaging external threads on the muzzle, and a front end with a threaded boss for engaging internal threads in the front plate.
