## Abstract

An adapter for an M240 machine gun to position the trigger housing assembly distally forward as well as an extended trigger housing assembly for an M240 machine gun and an M240 machine gun with the trigger housing assembly positioned distally forward from the proximal end of the receiver.

## Claims

### Claim 1

An M240 machine gun extended trigger housing assembly, comprising:
a trigger housing assembly having a proximal end and a distal end and connectable to an M240 machine gun receiver; and
a proximal leg extending proximally from the trigger housing assembly and configured to connect to a trigger housing assembly engagement of the M240 machine gun receiver;
wherein the extended trigger housing assembly is configured to position the trigger housing assembly with respect to the receiver at a position located more distal than that of a trigger housing assembly of an M240 machine gun as shown in FIG. 1.

### Claim 2 (depends on 1)

The extended trigger housing assembly of claim 1 wherein the trigger housing assembly comprises a removable grip.

### Claim 3

An M240 machine gun comprising:
a receiver with a floor, top, proximal end, and distal end;
a buttstock connected to the proximal end of the receiver;
a barrel connected to the distal end of the receiver; and
a trigger housing assembly comprising a grip, the trigger housing assembly attached to the bottom of the receiver and positioned more distal than a trigger housing assembly of an M240 machine gun as shown in FIG. 1.

### Claim 4 (depends on 3)

The M240 machine gun of claim 3 wherein the floor of the receiver further comprises an ejection port, trigger opening, and receiver floor wall, wherein the trigger opening is positioned between the receiver floor wall and the ejection port.

### Claim 5 (depends on 4)

The M240 machine gun of claim 4 wherein the bottom of the receiver further comprises a mounting hole positioned distal to both the receiver bottom wall and trigger opening and positioned proximal to the ejection port.

### Claim 6 (depends on 3)

The M240 machine gun of claim 3 wherein the trigger housing assembly further comprises a proximal leg for engaging a trigger housing assembly engagement on the receiver, the trigger housing assembly engagement located at about the proximal end of the receiver.

### Claim 7 (depends on 3)

The M240 machine gun of claim 3 further comprising an operating rod with a sear engagement located distally from the operating rod's rear body portion.

### Claim 8 (depends on 3)

The M240 machine gun of claim 3 wherein the butt stock has a length that is shorter than a length of a butt stock of an M240 machine gun as shown in FIG. 1.

### Claim 9 (depends on 3)

The M240 machine gun of claim 3 wherein the top of the receiver comprises a cheek rest.

### Claim 10 (depends on 3)

The M240 machine gun of claim 3 wherein the receiver comprises a unitary first shell and a unitary second shell that form the receiver.

### Claim 11 (depends on 10)

The M240 machine gun of claim 10 wherein the union of the unitary first shell and the unitary second shell form the ejection port and trigger opening with the trigger housing assembly attached in a forward position.

### Claim 12 (depends on 10)

The M240 machine gun of claim 10 wherein a proximal end of the grip of the trigger housing assembly is positioned at least about two inches from the proximal end of the receiver.

### Claim 13

An M240 machine gun, comprising:
a receiver with a floor, top, proximal end, and distal end;
a buttstock connected to the proximal end of the receiver;
a barrel connected to the distal end of the receiver; and
a trigger housing assembly comprising a grip, the trigger housing assembly attached to the bottom of the receiver;
wherein a proximal end of the grip of the trigger housing assembly is positioned at least about two inches from the proximal end of the receiver.

### Claim 14 (depends on 1)

An M240 machine gun comprising the extended trigger housing assembly of claim 1.
