Weapons System Construction And Modification

Abstract

This invention is directed to a rifle barrel and a method for modifying a pre-existing rifle barrel comprising dissembling said pre-existing rifle so that said barrel is removed from said pre-existing rifle placing said barrel in a sleeve having an inner diameter larger then said diameter of said barrel for receiving said barrel thereby defining a void arranged between said barrel and said sleeve when said barrel is placed in said sleeve reducing the outer diameter of said barrel near the breach end of said barrel so that said sleeve will cover said barrel up to the action of said rifle when said barrel is placed in said sleeve filling said void defined by said barrel and said sleeve with filler material attaching a weld-on thread assemble to said sleeve at the muzzle end of said barrel and assembling said pre-existing rifle with said barrel placed in said sleeve.

         10 . The method of  claim 1  including:
 removing all accessories forward said action of said barrel prior to placing said barrel in said sleeve; and, 
 attaching said accessories to said sleeve. 
 
     
     
         11 . The method of  claim 1  including increasing the diameter of the portion of the rifle stock that received the barrel and action of said pre-existing rifle to accommodate the diameter of said sleeve when said pre-existing rifle is assembled with said barrel placed in said sleeve. 
     
     
         12 . The method of  claim 1  including re-crowning said barrel. 
     
     
         13 . The method of  claim 1  including cutting a shoulder stop in said barrel generally at the action end of said barrel so that said sleeve covers said barrel from said shoulder stop to the muzzle. 
     
     
         14 . The method of clam  1  including painting said barrel prior to inserting said barrel into said sleeve and prior to filling said void. 
     
     
         15 . The method of  claim 1  wherein said sleeve is less than 5 meters in length and the bore of said barrel has a diameter less than 20 mm. 
     
     
         16 . A modified rifle barrel prepared by the method of  claim 1 . 
     
     
         17 . The method of  claim 1  wherein said filler material is made from material from the group of calcium sulfate, cement, amorphous silica, alumina, limestone dust, clay, quartz, calcium hydroxide calcium sulfo aluminate, perlite and any combination thereof. 
     
     
         18 . A method for modifying a pre-existing rifle barrel comprising:
 providing a sleeve having a diameter larger than said outer diameter of said barrel for receiving said barrel thereby defining a void arranged between said barrel and said sleeve when said barrel is placed in said sleeve;   modifying said barrel to reduce the diameter of said barrel near the breach area of said barrel so that said sleeve will cover said barrel up to the action when said barrel is placed in said sleeve;   placing said barrel in said sleeve so that said sleeve covers said barrel forward said action;   filling said void defined by said barrel and said sleeve with filler material; and,   attaching an end cap to said sleeve.   
     
     
         19 . The method of  claim 18  including cutting at least one circumferential groove in said barrel located generally at the muzzle end of said barrel.
