         2 . The jig of  claim 1 , wherein the jig is made from 303 stainless steel, 304F stainless steel, 416 stainless steel, 304 stainless steel, 316 stainless steel, 12L14 carbon steel, or combinations thereof. 
     
     
         3 . The jig of  claim 1 , wherein the jig is made from aluminum alloys. 
     
     
         4 . The jig of  claim 3 , further comprising a stainless-steel press bushing fitting within each alignment bore hole of the pair of alignment bore holes. 
     
     
         5 . The jig of  claim 1 , wherein each alignment bore hole of the pair of alignment bore holes are between 0.190 and 0.210 inches from an outer edge the body member. 
     
     
         6 . The jig of  claim 1 , wherein each alignment bore hole of the pair of alignment bore holes are between 0.760 and 0.770 inches from a bottom edge of the body member. 
     
     
         7 . The jig of  claim 1 , wherein the takedown bore plug has a diameter between 0.260 and 0.270 inches. 
     
     
         8 . A method of utilizing a jig to convert a semi-automatic style firearm to an automatic style firearm, the jig including a body member having a first side and a second side opposing the first side, a safety selector bore plug protruding from a first side of the body member, a takedown bore plug protruding from the first side of the body member in a position beneath the safety selector bore plug, and a first and second alignment bore holes extending from the first side of the body member to the second side of the body member, the semi-automatic firearm including a lower receiver having a first side and a second side opposing the first side, a safety selector bore and a takedown bore, the method comprising:
 (a) inserting the safety selector bore plug into the safety selector bore and the takedown bore plug into the takedown bore on the first side of the lower receiver;   (b) utilizing the first alignment bore hole to drill a first hole into the first side of the lower receiver;   (c) inserting the safety selector bore plug into the safety selector bore and the takedown bore plug into the takedown bore on the second side of the lower receiver; and   (d) utilizing the second alignment bore hole to drill a second hole into the first side of the lower receiver, thereby utilizing the jig to convert the semi-automatic style firearm to the automatic style firearm.   
     
     
         9 . The method of  claim 8 , wherein the first hole is circumferentially offset 180 degrees from the second hole. 
     
     
         10 . The method of  claim 8 , wherein the semi-automatic style firearm is an AR-15 style semi-automatic firearm. 
     
     
         11 . The method of  claim 8 , wherein the semi-automatic style firearm is an AR-10 style semi-automatic firearm.
