Abstract

An under folding firearm stock assembly includes an elongated main body having a longitudinal channel and a firing mechanism opening. A stock and butt stock are positioned along the back of the main body, and a pivot assembly transitions the stock between an open and closed position. The barreled front stock assembly can separate from the back receiver stock assembly.

What is claimed is: 
     
         1 . An under folding firearm stock assembly, said stock assembly comprising:
 an elongated body that can be separated into a barrel section and a receiver section having a front end, a back end, a pair of opposing generally parallel side walls joined together by a bottom wall and forming a generally U shaped channel;   a grip positioned adjacent to the back end of the main body and secured to the bottom wall on a surface opposite to the generally U shaped channel;   a firing mechanism opening disposed within the bottom wall at a location adjacent to the grip, and a ridge disposed within the firing mechanism opening;   a bolt opening disposed along the bottom wall of the main body, wherein said bolt opening, being interposed between the firing mechanism opening and the front end of the main body, wherein said bolt opening, firearm receiver opening and ridge are configured to receive and engage a conventional firing mechanism;   an elongated stock that includes a pair of laterally spaced arms each having a first end and a second end, and a butt stock pivotally secured to the second end of each of the laterally spaced arms; and,   a pivot assembly disposed along the back end of the main body, said pivot assembly being in communication with the first end of each of the laterally spaced arms, and being configured to transition the elongated stock from an open position to a closed position.   
     
     
         2 . The under folding firearm stock assembly of  claim 1 , wherein the elongated stock is configured to pivot 180 degrees about the pivot assembly. 
     
     
         3 . (canceled) 
     
     
         4 . The under folding firearm stock assembly of  claim 1 , wherein the grip is configured to be removable. 
     
     
         5 . The under folding firearm stock assembly of  claim 1 , wherein the a top surface of the bottom wall includes a plurality of raised sections configured to engage the conventional firing mechanism. 
     
     
         6 . The under folding firearm stock assembly of  claim 1 , wherein the pivot assembly is configured to lock each of the laterally spaced arms in a direction in-line and away from the back end of the main body in the open position. 
     
     
         7 . The under folding firearm stock assembly of  claim 1 , wherein the pivot assembly is configured to lock each of the laterally spaced arms alongside the side walls of the main body in the closed position. 
     
     
         8 . The under folding firearm stock assembly of  claim 1 , wherein the butt stock is configured to pivot between an open position and a closed position. 
     
     
         9 . The under folding firearm stock assembly of  claim 1 , wherein the butt stock is configured to make contact with the surface opposite to the general U shaped channel of the bottom wall of the main body when each of the elongated stock and the butt stock are in the closed positions, respectively. 
     
     
         10 . An under folding firearm stock assembly, said stock assembly comprising: means for receiving a firing mechanism of a rifle;
 a barreled front stock assembly can separate from a back receiver stock assembly;   a removable hand grip secured to the bottom of the means for receiving;   means for securing the firing mechanism to the means for receiving;   
       a pair of laterally spaced arms each having a first end and a second end, and a butt stock pivotally secured to the second end of each of the laterally spaced arms, each of the laterally spaced arms being secured to a first end of the means for receiving; and,
 means for pivoting each of the laterally spaced arms between an open position and a closed position.
