Ar-15 type bullpup converted firearm and method of assembly thereof

Abstract

A bullpup assembly for converting an AR-15 type firearm having an AR-15 stock in unmodified assembly into a bullpup configuration. The bullpup assembly includes a frame body coupleable with the body of the firearm, the frame comprising a bullpup trigger, and the frame being configured to replace the AR-15 stock, and a trigger link coupled with the bullpup trigger and coupleable with a firearm trigger of the firearm, wherein actuation of the bullpup trigger actuates the firearm trigger via the trigger link.

1 . A bullpup assembly for converting an AR-15 type firearm having an AR-15 stock in unmodified assembly into a bullpup configuration, comprising:
 a frame body coupleable with the body of the firearm, the frame comprising a bullpup trigger, and the frame being configured to replace the AR-15 stock; and   a trigger link coupled with the bullpup trigger and coupleable with a firearm trigger of the firearm,   wherein actuation of the bullpup trigger actuates the firearm trigger via the trigger link.   
     
     
         2 . The bullpup assembly of  claim 1 , further comprising:
 a shoulder butt coupleable with an end of the firearm.   
     
     
         3 . The bullpup assembly of  claim 1 , wherein the frame body comprises openings coupleable with a sight locking pin of the firearm. 
     
     
         4 . The bullpup assembly of  claim 1 , wherein the frame body comprises a handle adjacent to the bullpup trigger. 
     
     
         5 . The bullpup assembly of  claim 1 , wherein the bullpup trigger is linearly coupled within the frame body via a coupling mechanism. 
     
     
         6 . The bullpup assembly of  claim 1 , wherein the trigger link is configured to extend past a magazine of the firearm. 
     
     
         7 . The bullpup assembly of  claim 4 , wherein the lower frame body further comprises a second handle. 
     
     
         8 . The bullpup assembly of  claim 1 , further comprising:
 a firearm trigger engagement feature coupled to an end portion of the trigger link,   wherein the firearm trigger engagement feature is configured to abut the firearm trigger.   
     
     
         9 . The bullpup assembly of  claim 1 , wherein the frame body comprises an interior cavity, and wherein the trigger link is disposed within the interior cavity. 
     
     
         10 . The bullpup assembly of  claim 1 , wherein the frame body comprises a trigger guard adjacent the bullpup trigger. 
     
     
         11 . The bullpup assembly of  claim 1 , wherein the frame body further comprises a securing mechanism alignable with a receiving surface disposed at an end of the firearm. 
     
     
         12 . The bullpup assembly of  claim 1 , wherein an upper surface of the frame body is configured to abut corresponding surface features of the firearm. 
     
     
         13 . The bullpup assembly of  claim 11 , wherein the frame body is secured to the firearm when the securing mechanism is coupled to the receiving surface. 
     
     
         14 . The bullpup assembly of  claim 7 , wherein the second handle is retractable by pivoting about a pivot point. 
     
     
         15 . A method of converting an AR-15 type firearm into a bullpup configuration, the method comprising:
 removing a stock and a handle from the AR-15 type firearm;   mating a lower portion of the firearm with a frame body, the frame body comprising a bullpup trigger and a trigger link coupled with the bullpup trigger; and   coupling the trigger link with a trigger of the firearm such that actuation of the bullpup trigger actuates the firearm trigger via the trigger link.   
     
     
         16 . The method of  claim 15 , wherein the frame body further comprises a firearm trigger engagement feature coupled to an end portion of the trigger link, and wherein coupling the trigger link with the trigger of the firearm comprises abutting the firearm trigger engagement feature with the firearm trigger. 
     
     
         17 . The method of  claim 15 , further comprising:
 coupling a shoulder butt with an end of the firearm.   
     
     
         18 . The method of  claim 15 , wherein the frame body comprises openings,
 the method further comprising:
 securing the frame body to the firearm by mating a sight locking pin of the firearm with the openings. 
   
     
     
         19 . The meth of  claim 15 , wherein the frame body further comprises a securing mechanism,
 the method further comprising:
 securing the frame body to the firearm by mating the securing mechanism to a receiving surface disposed at an end of the firearm. 
   
     
     
         20 . The method of  claim 1 , further comprising:
 abutting an upper surface of the frame body with corresponding surface features of the firearm.
