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.

         37 . A method for reducing barrel whip in a rifle, comprising:
 encircling at least one weapon barrel with a sleeve, wherein the sleeve possesses a muzzle opening and a breech opening, wherein the barrel includes a bore with a caliber of 12 gauge or less and a breech;   defining a void between the at least one weapon barrel and the sleeve;   forming a seal at the breech opening between the at least one weapon barrel and sleeve wherein the sleeve extends over at least a portion of the breech;   placing the at least one weapon barrel and sleeve in a substantially vertical position;   aligning the at least one weapon barrel to be substantially centered within the sleeve;   at least partially filling the void with filler material wherein the filler material comprises at least 50% by weight of calcium sulfate; and,   allowing the filler material to cure.   
     
     
         38 . The method of  claim 37 , wherein an outer diameter of the at least one weapon barrel is reduced. 
     
     
         39 . The method of  claim 38 , wherein the outer diameter of the at least one weapon barrel is reduced adjacent the breech end of the at least one weapon barrel. 
     
     
         40 . The method of  claim 37 , wherein the breech opening is located substantially adjacent to a breech of the weapon. 
     
     
         41 . The method of  claim 37 , including the step of dissembling a rifle prior to encircling at least one weapon barrel with the sleeve. 
     
     
         42 . The method of  claim 37 , wherein the at least one weapon barrel is centered within the sleeve using a barrel centering member. 
     
     
         43 . The method of  claim 37 , wherein the filler material comprises at least 50% by weight calcium sulfate and less than 48% by weight portland cement. 
     
     
         44 . The method of  claim 37 , wherein the filler material includes material taken from the group consisting of: amorphous silica, alumina, limestone dust, clay, quartz, calcium hydroxide and calcium sulfo aluminate. 
     
     
         45 . (canceled) 
     
     
         46 . The method of  claim 37 , wherein the filler material comprises metal shavings. 
     
     
         47 . The method of  claim 37 , wherein a muzzle brake is installed once the void is at least partially filled with filler material. 
     
     
         48 . The method of  claim 37 , wherein a stock of the weapon is modified to receive the weapon barrel once the sleeve is affixed. 
     
     
         49 . The method of  claim 37 , wherein at least one circumferential groove is cut into the at least one weapon barrel. 
     
     
         50 . The method of  claim 37 , wherein a section of the distal end of the at least one weapon barrel is heated after partially filling the void. 
     
     
         51 - 56 . (canceled) 
     
     
         57 . A method for increasing accuracy in a rifle, comprising:
 encircling at least one weapon barrel with a sleeve, wherein the sleeve possesses a muzzle opening and a breech opening, wherein the barrel includes a bore with a caliber of 12 gauge or less and a breech;   defining a void between the at least one weapon barrel and the sleeve;   forming a seal at the breech opening between the at least one weapon barrel and sleeve wherein the sleeve extends over at least a portion of the breech;   placing the at least one weapon barrel and sleeve in a substantially vertical position;   aligning the at least one weapon barrel to be substantially centered within the sleeve;   at least partially filling the void with filler material wherein the filler material comprises at least 50% by weight of calcium sulfate; and,   allowing the filler material to cure.
