Systems and methods for multiple component firearm receiver

Abstract

Systems and methods for firearm receivers are described. Systems may include a receiver body, a tail; and a connection for coupling the receiver body to the tail. The receiver body and the tail may be made from different materials. A receiver system coupling apparatus may include one or more protrusions on a receiver body; and one or more one or more protrusions on a tail. The one or more protrusions on the receiver body may be coupled to the one or more protrusions on the tail to secure the receiver body to the tail. A method for producing a multiple component receiver system may include creating a receiver body from a first material; creating a tail from a second material; and coupling the receiver body to the tail with a connection.

What is claimed is: 
     
         1 . A receiver system comprising:
 a receiver body;   a tail; and   a connection for coupling the receiver body to the tail,   wherein the receiver body and the tail are made from different materials.   
     
     
         2 . The system of  claim 1 , wherein the connection comprises one or more pins. 
     
     
         3 . The system of  claim 2 , wherein the one or more pins are fitted through openings on the receiver body and the tail. 
     
     
         4 . The system of  claim 1 , wherein the receiver body and the tail comprise heat treatable steels each with different inherent hardness characteristics or different hardness characteristics created by different heat treatments. 
     
     
         5 . The system of  claim 1 , wherein the materials for the receiver body are selected from the group consisting of: heat treatable steels, aluminum, titanium, plastic, polymer, and combinations thereof, and the materials for the tail are selected from the group consisting of: heat treatable steels, aluminum, magnesium, titanium, plastic, polymer, and combinations thereof 
     
     
         6 . A receiver system coupling apparatus comprising:
 one or more protrusions on a receiver body; and   one or more one or more protrusions on a tail;   wherein the one or more protrusions on the receiver body are coupled to the one or more protrusions on the tail to secure the receiver body to the tail.   
     
     
         7 . The apparatus of  claim 6 , further comprising one or more pins. 
     
     
         8 . The apparatus of  claim 7 , wherein the one or more pins are fitted through openings on the receiver body and the tail. 
     
     
         9 . A method for producing a multiple component receiver system, the method comprising:
 creating a receiver body from a first material;   creating a tail from a second material; and   coupling the receiver body to the tail with a connection.   
     
     
         10 . The method of  claim 9 , wherein the connection comprises one or more pins. 
     
     
         11 . The method of  claim 10 , wherein the one or more pins are fitted through openings on the receiver body and the tail. 
     
     
         12 . The method of  claim 9 , wherein the creating the receiver body comprises machining from bar stock material. 
     
     
         13 . The method of  claim 12 , further comprising turn-milling at least a portion of the receiver body. 
     
     
         14 . The method of  claim 9 , further comprising heat treating at least one of the receiver body and the tail. 
     
     
         15 . The method of  claim 14 , wherein the heat treating is a local induction process. 
     
     
         16 . The method of  claim 14 , wherein the heat treating is a global process. 
     
     
         17 . The method of  claim 9 , wherein the creating the tail comprises casting and then machining 
     
     
         18 . The method of  claim 9 , wherein the creating the tail consists of machining 
     
     
         19 . The method of  claim 9 , wherein the creating the tail comprises metal injection molding. 
     
     
         20 . The method of  claim 9 , wherein the creating the tail comprises a powder metal process.
