## Abstract

An apparatus for mounting accessories on a weapon mount. One embodiment of the apparatus includes an accessory interface system having a forward module coupled to a mounting module. The mounting module of the accessory interface system mounts on a weapon mount. The forward module of the accessory interface system provides a plurality of surfaces for mounting weapon accessories.

## Claims

### Claim 1

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module;
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
forming an ancillary module; and
removably coupling said ancillary module to said forward module;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said first force level is at least a 20 G load.

### Claim 2

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module; and
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said first force level is at least a 20 G load.

### Claim 3

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module; and
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said first force level is a 20 G load.

### Claim 4

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module; and
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said second force level is 120 kilograms per square inch.

### Claim 5

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module; and
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said second force level is 175 kilograms per square inch.

### Claim 6

A method of making an accessory interface system, comprising the steps of:
forming a forward module having a plurality of mounting surfaces;
forming each of said plurality of mounting surface being substantially aligned to a common center line in an interior of the forward module;
forming a mounting module;
coupling said mounting module to said forward module, said mounting module adapted to be coupled to a weapon mount;
forming an ancillary module; and
removably coupling said ancillary module to said forward module;
wherein said step of coupling further comprises forming a coupling system, such that coupling system maintains its coupling when subject to a force up to at least a first force level and when subject to a force that exceeds a second force level, the coupling system un-couples;
wherein said second force level is at least 120 kilograms per square inch.
