Insert for a firearm suppressor

Abstract

A suppressor for a firearm defines a linear projectile path. The suppressor may include an inner body. The inner body may include a proximal wall and a plurality of baffles. Each baffle may define a baffle opening that is positioned on the linear projectile path. An expansion chamber may be defined between the proximal wall and a first baffle of the plurality of baffles that is nearest to the proximal wall. The suppressor may include an insert that extends through at least one baffle opening. A gap may be defined between the insert and the proximal wall.

         6 . The suppressor of  claim 5 , further comprising a nut positioned forward of the inner body relative to a shooting orientation, wherein:
 the insert comprises a threaded portion configured to couple to the nut,   the diameter of the cap portion is greater than a diameter of the baffle opening of the first baffle,   the cap portion is positioned aft of and in contact with the first baffle,   the insert extends through an opening of a distal wall of the inner body, and   the threaded portion of the insert is positioned forward of the distal wall of the inner body.   
     
     
         7 . The suppressor of  claim 6 , further comprising a shroud that has an end plate, wherein:
 the end plate of the shroud defines an opening,   the insert extends through the opening of the end plate of the shroud,   the end plate of the shroud is positioned between the nut and the distal wall of the inner body, and   an outer diameter of the nut is greater than the diameter of the opening of the end plate of the shroud.   
     
     
         8 . The suppressor of  claim 1 , wherein the insert comprises a plurality of insert openings defined along and extending through a main body of the insert. 
     
     
         9 . The suppressor of  claim 8 , wherein the plurality of insert openings are staggered relative to a circumferential direction defined by the insert. 
     
     
         10 . The suppressor of  claim 1 , further comprising a nut positioned forward of the inner body relative to a shooting orientation, wherein the insert comprises a threaded portion configured to couple to the nut. 
     
     
         11 . The suppressor of  claim 1 , wherein the inner body comprises a plurality of inner body openings that are each defined between adjacent baffles of the plurality of baffles. 
     
     
         12 . The suppressor of  claim 1 , further comprising a shroud that circumferentially surrounds at least a portion of the inner body. 
     
     
         13 . The suppressor of  claim 12 , wherein the shroud comprises a plurality of shroud openings that each extend parallel to the linear projectile path and collectively extend circumferentially around the linear projectile path. 
     
     
         14 . The suppressor of  claim 1 , wherein the inner body comprises a muzzle attachment portion that defines an opening that is positioned on the linear projectile path, and wherein a smallest diameter of the opening is greater than a largest diameter of the insert. 
     
     
         15 . A firearm comprising:
 a barrel;   a muzzle device coupled to the barrel; and   the suppressor of  claim 1  coupled to the muzzle device.   
     
     
         16 . A suppressor for a firearm, the suppressor defining a linear projectile path, the suppressor comprising:
 an inner body comprising:
 a proximal wall; and 
 a plurality of baffles, each baffle defining a baffle opening that is positioned on the linear projectile path, 
 wherein an expansion chamber is defined between the proximal wall and a first baffle of the plurality of baffles that is nearest to the proximal wall, and at least a portion of the expansion chamber is positioned on the linear projectile path; and 
   a means for reducing an amount of spark ejected from the suppressor when the firearm is discharged.
