Abstract

A multipurpose weapon having a self-loading large-caliber self-loading rifle module or section and an assault weapon module or section attached to the front portion of the large caliber rifle is provided. A first trigger assembly of the large-caliber rifle is positioned for operation by a trigger hand of the user of the weapon, while a second trigger assembly of the assault weapon module is configured for operation by the non-trigger hand of the user. Alternatively, the assault weapon section or module can be equipped with a trigger that is selectively operable to fire either the assault weapon module or the large-caliber rifle module. Additionally, a detachable secondary module comprising a grip module which includes a grip and a trigger can alternatively be attached to the large-caliber module.

Claims

1. A multipurpose weapon comprising:

a large-caliber rifle module having a housing with a shoulder support at one end, a longitudinally extending large-caliber barrel contained in the housing for discharging relatively larger caliber projectiles; and

a secondary module including a hand support, a barrel for discharging relatively smaller caliber assault rifle cartridges and a trigger mechanism which upon actuation discharges either the large-caliber rifle module or the secondary module, and a coupling arrangement for releasably attaching the secondary module to the large-caliber rifle module such that the secondary module is selectively detachable and operable independently from the large caliber rifle module and reattachable thereto.

2. The invention according to claim 1 further including a sighting device for use with both the large-caliber rifle module and the secondary module.

3. The invention according to claim 1 wherein the trigger mechanism includes a module selector for selectively switching the trigger mechanism between actuating discharge of the large-caliber rifle module and actuating discharge of the secondary module.

4. The invention according to claim 1, wherein the secondary module is removably mounted to the large-caliber rifle housing by a slide-on mounting arrangement.

5. The invention according to claim 1, further including a shock absorber disposed adjacent to the shoulder support for recoil absorption.

6. The invention according to claim 5, wherein the shock absorber is a hydraulic shock absorber.

7. The invention according to claim 1, wherein the secondary module is mounted substantially below the barrel of the large-caliber module.
