A system includes a movable assembly configured for pushing a piece of ammunition into a breech ring of a firearm and/or closing the breech ring, under control of a motor. A feeding device is configured for feeding the piece of ammunition into a position situated between the movable assembly and the breech ring. A synchronization device co-operates with the motor on one side and with the feeding device on the other side. The synchronization mechanism provides for selective transmission of motion, under control of the movable assembly, from the motor to the feeding mechanism, when the movable assembly is in a position away from the breech ring.

A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.

An apparatus for loading cartridges into a firearms magazine includes a loader body comprising a retainer configured for holding a firearms magazine, and cooperating spring-loaded plungers coupled thereto. A first spring-loaded plunger coupled to the loader body is oriented for pushing one or more cartridges into the firearms magazine so as to depress a magazine spring thereof. A second plunger coupled to the loader body is oriented for inserting cartridges into the firearms magazine without further depressing the magazine spring while the first spring-loaded plunger is depressing the magazine spring. A mechanism automatically resets the first spring-loaded plunger after the second plunger completes insertion of each cartridge into the magazine. All of the foregoing moving parts may be manually or motor driven and fed with cartridges via a hopper.
