Abstract: A loader for inserting an ammunition cartridge into a gun's magazine includes a body operable to hold two or more ammunition cartridges, a retainer to prevent a cartridge held by the body from leaving the body and operable to release a held cartridge from the body to position the cartridge for insertion into a gun's magazine, and an insertion component to exert pressure on a positioned cartridge to insert the cartridge into the gun's magazine. When the loader is used to insert a cartridge into a gun's magazine, the insertion component extends into the gun's carrier opening, a cartridge from the body is positioned on the insertion component, and the body is then moved relative to the gun's magazine. By holding the cartridges with the body and forcing a positioned cartridge into the gun's magazine with the insertion component, one can quickly and efficiently load a gun's magazine.

Abstract: An ambidextrous charging handle for a firearm consists of an oblong handle having a crossbar section. A cavity is formed in the oblong handle and includes a slotted portion. A longitudinal central shaft extends generally perpendicularly from the crossbar section of the oblong handle and terminates in a bolt hook at a distal end. A pivotable latch in the cavity includes a latch cam portion and a latch hook. A plunger has a plunger cam portion and is slidably disposed in the slotted portion of the cavity. A biasing element urges the latch hook toward the central shaft. Slidable movement of the plunger in the slotted portion of the cavity, against the bias of the biasing element, urges the cam portion of the plunger against the latch cam portion, thereby pivoting the latch and urging the latch hook away from the central shaft.

Abstract: A device for suppressing noise from a firearm. In one aspect, the suppressor has an elongate body that defines a bullet pathway extending longitudinally therethrough. The elongate body may define a plurality of adjacent chambers spaced along its longitudinal axis. The suppressor may also have at least two elongate body shells configured to selectively substantially envelop the elongate body and substantially enclose each of the adjacent chambers. The body shells of the suppressor are designed to be easily removed to clean the chambers of the suppressor.

Abstract: An hydraulically deployable vehicle defense shield having a plurality of coplanar ballistic resistant elements in a single defense barrier that provides protection from the side to the vehicles engine and tires when non-deployed and when deployed provides cover for personnel exiting the vehicle and during a firefight. The defense barrier may also be deployed for the purpose of ramming another vehicle.

In particular, tools connected to remotely controllable robots include disruptor guns for firing disruptive materials at the targets and disruptive devices filled with explosive materials, e.g., water, for controllably detonating or disrupting the detonation of the targets when placed in close proximity thereto.

Abstract: A method and apparatus are disclosed for substituting a different stock, or a different receiver assembly, in a long gun (e.g., a shotgun) without the use of tools by a user in the field. Applicants' preferred apparatus comprises: a long gun (e.g., an illustrated shotgun) having a stock and a receiver assembly; and an adaptor assembly which removably interconnects the stock to the receiver assembly, wherein the adaptor assembly includes: an adaptor base affixed to the receiver; an end of the stock is mounted onto the adaptor base; and a rotatable locking pin, continuously attached to the base, which can be lifted up and rotated or turned on its axis by 90° to unlock the adaptor assembly. The stock can then be pulled off the adaptor base. Upon a new stock being mounted on the adaptor base, the locking pin can be rotated back to its original orientation and pushed down to lock the adaptor assembly, whereupon the adaptor assembly interconnects the substitute stock with the receiver assembly.
