Systems, devices, and methods for a firearm suppressor assembly

Abstract

The disclosure generally relates to systems, devices, and methods for sound suppression for firearms. In various embodiments, the firearm suppressor can include a barrel system of a predetermined length to prevent supersonic projectile (e.g., bullet) speed. Further, the firearm suppressor can include a plurality of chambers that can substantially contain the gases released from a projectile and thereby reduce the sound generated by the expansion of the gases release upon firing the projectile.

1 . A firearm barrel comprising a first, second, and third portion, wherein:
 the first portion comprises a longitudinal bore of a predetermined length suitable to prevent supersonic projectile speed;   the second portion comprises a plurality of longitudinal chambers aligned with the longitudinal bore of the first portion; and   the third portion comprises a tubular sleeve configured to slide over the second portion and substantially enclose the second portion.   
     
     
         2 . The firearm barrel of  claim 1 , wherein further, the second portion comprises a first end proximate to the first portion and a second end distal to the first portion of the firearm barrel. 
     
     
         3 . The firearm barrel of  claim 2 , wherein the plurality of longitudinal chambers increases in size from the first end to the second end of the firearm barrel. 
     
     
         4 . The firearm barrel of  claim 2 , wherein the longitudinal bore of the first portion is about 4 inches in diameter. 
     
     
         5 . The firearm barrel of  claim 1 , wherein the first portion comprises a predetermined twist. 
     
     
         6 . The firearm barrel of  claim 5 , wherein the predetermined twist is a 1:16 twist. 
     
     
         7 . The firearm barrel of  claim 5 , wherein the predetermined twist comprises a land and groove micro-twist. 
     
     
         8 . The firearm barrel of  claim 2 , wherein the tubular sleeve comprises a titanium alloy. 
     
     
         9 . The firearm barrel of  claim 2 , wherein the distal end of the second portion comprises a threaded end. 
     
     
         10 . The firearm barrel of  claim 9 , wherein the third portion further comprises a separate sleeve retainment cap threaded on to the threaded end. 
     
     
         11 . The firearm barrel of  claim 10 , wherein the sleeve retainment cap comprises a titanium alloy.
