Device to improve firearm precision

Abstract

A barrel device includes a breech cap, a muzzle cap, a collet, and a main body. The breech cap has a first threaded portion and the muzzle cap has a second threaded portion. The main body has a first threaded portion and a second threaded portion. The first threaded portion of the main body is engaged with the first threaded portion of the breech cap and the second threaded portion of the main body is engaged with the second threaded portion of the muzzle cap. The collet is encircled by the main body. The barrel device provides a compressive force on the end of the barrel.

What is claimed is: 
     
         1 . A barrel device comprising:
 a breech cap, the breech cap having a first threaded portion;   a muzzle cap, the muzzle cap having a second threaded portion;   a collet; and   a main body, wherein the main body has a first threaded portion and a second threaded portion, the first threaded portion being engaged with the first threaded portion of the breech cap and the second threaded portion being engaged with the second threaded portion of the muzzle cap, and wherein the collet is encircled by the main body.   
     
     
         2 . The barrel device of  claim 1 , further comprising a sleeve, at least a portion of the sleeve extending around at least a portion of the barrel. 
     
     
         3 . The barrel device of  claim 1 , wherein the main body has an interior portion, wherein at least a portion of the interior portion is conical. 
     
     
         4 . The barrel device of  claim 1 , wherein the first threaded portion of the breech cap comprises external threads. 
     
     
         5 . The barrel device of  claim 1 , wherein the second threaded portion of the muzzle cap comprises external threads. 
     
     
         6 . The barrel device of  claim 1 , wherein the muzzle cap has an inner bore, and the inner bore is larger than a bore diameter of the barrel. 
     
     
         7 . The barrel device of  claim 1 , wherein the muzzle cap abuts a distal end of the barrel. 
     
     
         8 . The barrel device of  claim 2 , wherein the sleeve is less than one inch in length. 
     
     
         9 . The barrel device of  claim 1 , wherein the muzzle cap further comprises a third threaded portion. 
     
     
         10 . The barrel device of  claim 9 , wherein the third threaded portion of the muzzle cap is disposed along a distal end portion of the muzzle cap. 
     
     
         11 . The barrel device of  claim 1 , wherein the sleeve has a wall thickness, and wherein the wall thickness varies along the length of the sleeve. 
     
     
         12 . A kit comprising:
 a sleeve,   a breech cap, the breech cap having a first threaded portion;   a muzzle cap, the muzzle cap having a second threaded portion;   a collet, the collet configured to extend around at least a portion of the sleeve;   a main body, the main body configured to extend around at least a portion of the collet;   and   a disassembly tool.   
     
     
         13 . The kit of claim of  claim 12 , wherein the disassembly tool comprises a counterbore. 
     
     
         14 . A barrel device for compressing a portion of a barrel, the barrel device comprising:
 a hollow body, the hollow body having an internal profile matching the profile of a barrel.   
     
     
         15 . The barrel device of  claim 14 , wherein the barrel device is formed from a first material that is different from the material of the barrel. 
     
     
         16 . The barrel device of  claim 14 , wherein the barrel device is formed from a first material and the barrel is formed from a second material, wherein the first material is the same as the second material. 
     
     
         17 . A method of applying a barrel device to a barrel comprising:
 providing a barrel having a distal end thereof;   providing a barrel device, the barrel device having an aperture;   heating the barrel device; and   disposing the aperture of the heated barrel device over the distal portion of the barrel.   
     
     
         18 . The method of  claim 17 , wherein the step of providing a barrel comprises providing a barrel having a first material and the step of providing a barrel device comprises providing a barrel having a second material different from the first material. 
     
     
         19 . The method of  claim 17 , further comprising cooling the barrel device. 
     
     
         20 . The method of  claim 19 , further comprising compressing the distal portion of the barrel with the barrel device upon cooling of the barrel device. 
     
     
         21 . The method of  claim 17 , further comprising cooling the barrel device in the presence of a concentrated inert gas. 
     
     
         22 . The method of  claim 21 , wherein the concentrated inert gas has a concentration of at least 75% of a gas mixture.
