Firearm sound suppressor

Abstract

Implementations of a firearm sound suppressor are provided. The firearm sound suppressor comprises a non-cylindrical, monolithic baffle core that is enclosed by a front plate and a back plate. In some implementations, the baffle core may comprise a proximal end configured to mount onto the muzzle of a firearm barrel, a distal end having an outlet aperture, and a plurality of baffles. The plurality of baffles may be positioned transverse to a projectile pathway extending through the sound suppressor and form expansion chambers therebetween. In this way, propellant gasses generated by the discharge of a firearm may be dispersed throughout the interior of the sound suppressor, and directed away from the projectile pathway extending therethrough, by the shearing effect of each baffle. The baffle core may further comprise two longitudinally extending expansion chambers, each of which may be in fluid communication with ports extending through an exterior sidewall of the baffle core.

         3 . The sound suppressor of  claim 2 , wherein the first longitudinally extending expansion chamber is in fluid communication with at least one port extending through a first exterior sidewall of the baffle core; and wherein the second longitudinally extending expansion chamber is in fluid communication with at least one port extending through a second exterior sidewall of the baffle core. 
     
     
         4 . The sound suppressor of  claim 3 , wherein the first longitudinally extending expansion is positioned between the first interior sidewall and the first exterior sidewall of the baffle core; and wherein the second longitudinally extending expansion chamber is positioned between the second interior sidewall and the second exterior sidewall of the baffle core. 
     
     
         5 . The sound suppressor of  claim 1 , wherein the ridge feature of the at least one baffle includes an apex, the apex points towards the proximal end of the baffle core. 
     
     
         6 . The sound suppressor of  claim 1 , wherein the front plate and the back plate are removably secured to the baffle core. 
     
     
         7 . The sound suppressor of  claim 6 , wherein the front plate is secured to the first side of the baffle core by a plurality of threaded fasteners and the back plate is secured to the second side of the baffle core by a plurality of threaded fasteners. 
     
     
         8 . A sound suppressor for a firearm comprising:
 a baffle core, the baffle core comprises a proximal end having an inlet aperture, a distal end having an outlet aperture, a longitudinally extending rib feature, and at least one baffle positioned between the proximal end and the distal end to define a plurality of expansion chambers, the baffle core defines a longitudinally extending projectile pathway that extends from the inlet aperture to the outlet aperture;   wherein the at least one baffle is positioned transverse to the projectile pathway;   wherein the at least one baffle comprises a first curved member and a second curved member that extend from opposite sides of the longitudinally extending rib feature, one end of the first curved member is connected to a first interior sidewall of the baffle core, and one end of the second curved member is connected to a second interior sidewall of the baffle core;   wherein the longitudinally extending rib feature includes an aperture that extends therethrough, the aperture is coaxial with the longitudinally extending projectile pathway;   a front plate configured to cover a first side of the baffle core; and   a back plate configured to cover a second side of the baffle core.   
     
     
         9 . The sound suppressor of  claim 8 , wherein the baffle core further comprises a first longitudinally extending expansion chamber and a second longitudinally extending expansion chamber, each longitudinally extending expansion chambers is in fluid communication with an expansion chamber defined by the at least one baffle positioned transverse to the longitudinally extending projectile pathway of the baffle core.
