Barrel sleeve assembly

Abstract

The present invention relates to a barrel sleeve assembly for a rifle. The barrel sleeve assembly includes a rifle barrel and a sleeve. The rifle barrel has a portion that has been turned down from standard sizes. The sleeve is fitted over the turned down portion of the rifle barrel.

What is claimed is: 
     
         1 . A barrel sleeve assembly comprising:
 a rifle barrel having a turned down portion;   a sleeve fitted over the turned down portion of the rifle barrel.   
     
     
         2 . The barrel sleeve assembly of  claim 1  further comprising a bonding agent between the sleeve and the turned down portion of the rifle barrel. 
     
     
         3 . The barrel sleeve assembly of  claim 1  further comprising the rifle barrel having a threaded portion that matingly engages an inner surface of the sleeve. 
     
     
         4 . The barrel sleeve assembly of  claim 1  wherein the turned down portion is turned down to between 0.500 inches to 0.750 inches from standard dimensions. 
     
     
         5 . The barrel sleeve assembly of  claim 1  wherein an inner diameter of the sleeve is between 0.000 inches and 0.010 inches of tolerance of an outer diameter of the turned down portion of the rifle barrel. 
     
     
         6 . A method for making a barrel sleeve assembly comprising the steps of:
 turning down a portion of a rifle barrel;   cutting a sleeve;   coating the rifle barrel with a bonding agent; and   fitting the sleeve over the rifle barrel.   
     
     
         7 . The method of  claim 6  further comprising the step of placing the assembly under tension. 
     
     
         8 . The method of  claim 6  further comprising the step of threading a portion of the rifle barrel and the sleeve such that the threaded portions matingly engage one another. 
     
     
         9 . The method of  claim 6  further comprising the step of threading the entire length of the rifle barrel. 
     
     
         10 . The method of  claim 6  wherein the rifle barrel is turned down between 0.500 inches to 0.750 inches from standard dimensions. 
     
     
         11 . The method of  claim 6  wherein an inner diameter of the sleeve is between 0.000 inches and 0.010 inches of tolerance of an outer diameter of the turned down portion of the rifle barrel when the sleeve is fitted over the rifle barrel.
