Methods and systems for firearm suppression

Abstract

Structural suppressors and methods for the same are disclosed herein. The structural suppressor can be part of a weapon system. The weapon system can include a barrel portion having a proximal end attached to a receiver, a distal end, and a bore extending between the proximal end and the distal end. The weapon system can include a suppressor portion attached to the barrel portion. The suppressor portion can include: an insert; a tube that can receive the insert and part of the barrel portion; and a bushing engaged with the barrel portion and applying a tensile force to the barrel portion when the insert.

What is claimed is: 
     
         1 . A weapon system comprising:
 a barrel portion comprising a proximal end attached to a receiver, a distal end, and a bore extending between the proximal end and the distal end; and   a suppressor portion attached to the barrel portion and covering an internal part of the barrel portion, the suppressor portion having a proximal end and a distal end, the suppressor portion comprising:
 an insert comprising: a proximal end having a feature engaged with the barrel portion to affix the insert to the barrel portion; and a distal end comprising a cap, wherein a channel extends through the insert from the proximal end to the distal end; 
 a tube abutting the cap and enclosing an internal portion of the insert and the internal part of the barrel portion; and 
 a bushing engaged with the barrel portion and together with the insert applying a tensile force to the internal part of the barrel portion. 
   
     
     
         2 . The weapon system of  claim 1 , wherein the barrel portion comprises a portion having a first diameter, a first step, and a portion having a second diameter, wherein the first step separates the portion having the first diameter and the portion having the second diameter. 
     
     
         3 . The weapon system of  claim 2 , wherein the bushing and the cap of the insert apply a compressive force to the tube, and wherein the internal part of the barrel portion is between the distal end of the barrel portion and the first step. 
     
     
         4 . The weapon system of  claim 3 , wherein the barrel portion comprises a second threaded portion located at the distal end of the barrel portion. 
     
     
         5 . The weapon system of  claim 4 , wherein the insert feature engaged with the barrel portion comprises a threaded portion of the insert, and wherein the threaded portion of the insert is threadingly engaged with the second threaded portion of the barrel portion. 
     
     
         6 . The weapon system of  claim 5 , wherein the insert is monolithic. 
     
     
         7 . The weapon system of  claim 6 , wherein the insert comprises at least two baffles that together with the cap of the insert define at least two chambers. 
     
     
         8 . The weapon system of  claim 7 , wherein the insert comprises four baffles defining four chambers. 
     
     
         9 . The weapon system of  claim 7 , wherein at least one of the baffles together with the proximal end of the suppressor portion defines a pre-chamber. 
     
     
         10 . The weapon system of  claim 7 , wherein at least one of the baffles contacts the tube around the perimeter of the baffle, and wherein at least one of the baffles does not contact the tube around the perimeter of the baffle. 
     
     
         11 . The weapon system of  claim 10 , wherein the bushing and the tube are integral and together are a one part cover. 
     
     
         12 . The weapon system of  claim 10 , wherein the bushing and the tube are separate and together form a two-part cover. 
     
     
         13 . The weapon system of  claim 10 , wherein the bushing comprises an elevated tab. 
     
     
         14 . A method of suppressing a weapon system, the method comprising:
 providing a barrel comprising a proximal end, a distal end, and a bore extending between the proximal end and the distal end, wherein the barrel comprises a portion having a first diameter, a portion having a second diameter, and a first step intermediate between the portion having the first diameter and the portion having the second diameter;   inserting the barrel into a bushing so that a proximal face of the bushing abuts the first step;   inserting the barrel into a tube having a proximal end and a distal end;   attaching a proximal end of an insert to the distal end of the barrel, wherein the insert comprises a cap located at the distal end of the insert; and   proximally advancing the insert potion relative to the distal end of the barrel to apply a tensile force to the insert and the part of the barrel extending distally from the first step.   
     
     
         15 . The method of  claim 14 , wherein proximally advancing the insert relative to the distal end of the barrel further comprises applying a compressive force to the tube. 
     
     
         16 . The method of  claim 15 , wherein the compressive force is applied to the tube via the cap of the insert and the bushing abutting the first step. 
     
     
         17 . The method of  claim 16 , wherein the proximate end of the insert is attached to the distal end of the barrel via a second threaded portion located on the distal end of the barrel and a threaded portion at the proximal end of the insert. 
     
     
         18 . The method of  claim 17 , wherein the insert comprises at least two baffles that together with the cap of the insert define at least two chambers. 
     
     
         19 . The method of  claim 18 , wherein at least one of the baffles together with the bushing defines a pre-chamber. 
     
     
         20 . The method of  claim 18 , wherein at least one of the baffles contacts the tube around the perimeter of the baffle, and wherein at least one of the baffles does not contact the tube around the perimeter of the baffle.
