Firearm modification method and kit assembly

Abstract

A firearm modification method and kit assembly includes the removal of the pistol style hand grip mount in a manner that precludes the use of the originally mounted pistol style hand grip, the modification of the hand grip mount to add a shoulder stock mount, and the installation of a shoulder stock in place of the originally mounted pistol style hand grip and hand grip mount.

1 . A method for modifying a firearm having both a shoulder stock and a shoulder stock mount and a hand grip and a hand grip mount to eliminate the hand grip, comprising:
 removing the shoulder stock, hand grip and hand grip mount from the firearm;   installing a modified shoulder stock mount shaped to fit where the hand grip mount was attached to the firearm; and   fastening a modified shoulder stock to said modified shoulder stock mount.   
   
   
       2 . The method of  claim 1  wherein the firearm is a member of the M-16/AR-15 family of firearms. 
   
   
       3 . A method for modifying a firearm having both a shoulder stock and shoulder stock mount and a hand grip and hand grip mount to eliminate the hand grip, comprising:
 removing the shoulder stock and hand grip from the firearm;   removing sections from the pistol grip mount;   fabricating a modified shoulder stock mount sized to fit the remaining portion of the pistol grip mount;   installing said modified shoulder stock mount where the hand grip mount was attached to the firearm; and   fastening a modified shoulder stock to said modified shoulder stock mount.   
   
   
       4 . The method of  claim 3  wherein said modified shoulder stock mount is installed so as to be permanently attached to the firearm where the hand grip mount was attached. 
   
   
       5 . The method of  claim 4  wherein said modified shoulder stock mount is welded to said remaining portion of the pistol grip mount. 
   
   
       6 . The method of  claim 4  wherein said modified shoulder stock mount is bonded to said remaining portion of the pistol grip mount. 
   
   
       7 . The method of  claim 3  wherein the shoulder stock is fabricated from wood, metal, plastics, composites, or other appropriate material, to fit the shape of the stock mount. 
   
   
       8 . The method of  claim 3  wherein the firearm is a member of the M-16/AR-15 family of firearms. 
   
   
       9 . The method of  claim 3  further comprising modifying the firearm to have a front mounted recoil system. 
   
   
       10 . The method of  claim 3  further comprising modifying the firearm to have a short rear mounted recoil system. 
   
   
       11 . The method of  claim 3  further comprising reshaping the rear curve of the receiver to provide more hand room above the stock and to remove the anti-rotation detent found in M-16/AR-15 style firearms, to thereby preclude the secure mounting of the rifle's original style of shoulder stock in its normal position. 
   
   
       12 . An stock assembly kit for replacing shoulder stock, hand grip, and hand grip mount of an M-16 or AR-15 family of firearm, comprising:
 a modified shoulder stock mount shaped to be installed where the hand grip mount is installed on the firearm; and   a modified shoulder stock mount shaped to be installed on said modified shoulder stock mount.
