## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the connection comprises one or more pins.

### Claim 3 (depends on 2)

The system of claim 2, wherein the one or more pins are fitted through openings on the receiver body and the tail.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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

### Claim 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.

### Claim 7 (depends on 6)

The apparatus of claim 6, further comprising one or more pins.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the one or more pins are fitted through openings on the receiver body and the tail.

### Claim 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.

### Claim 10 (depends on 9)

The method of claim 9, wherein the connection comprises one or more pins.

### Claim 11 (depends on 10)

The method of claim 10, wherein the one or more pins are fitted through openings on the receiver body and the tail.

### Claim 12 (depends on 9)

The method of claim 9, wherein the creating the receiver body comprises machining from bar stock material.

### Claim 13 (depends on 12)

The method of claim 12, further comprising turn-milling at least a portion of the receiver body.

### Claim 14 (depends on 9)

The method of claim 9, further comprising heat treating at least one of the receiver body and the tail.

### Claim 15 (depends on 14)

The method of claim 14, wherein the heat treating is a local induction process.

### Claim 16 (depends on 14)

The method of claim 14, wherein the heat treating is a global process.

### Claim 17 (depends on 9)

The method of claim 9, wherein the creating the tail comprises casting and then machining

### Claim 18 (depends on 9)

The method of claim 9, wherein the creating the tail consists of machining

### Claim 19 (depends on 9)

The method of claim 9, wherein the creating the tail comprises metal injection molding.

### Claim 20 (depends on 9)

The method of claim 9, wherein the creating the tail comprises a powder metal process.
