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 firearm system is provided. A pump-action firearm, such as a shotgun, includes a buffer attached to a trigger housing. The buffer consists of a resilient or semi-resilient material and is positioned such as to face towards an opening the receiver in which the magazine tube is partially received. The buffer includes a contoured bottom surface and an upper surface, configured in a way which shortens the space available within an opening of a receiver while accommodating the loading of shells into a magazine tube. Upon moving a shell into the opening, such as by pumping the action, the shell impacts the buffer, which stabilizes the shell prior to being lifted by an elevators. For shorter shells, this reduces the risk of a jamming event. For longer shells, the buffer is configured to compress to accommodate the additional length.

A vehicle, in particular a tank, having a turret, on which a gun having a large-calibre gun barrel is secured, and comprising an auto-loader positioned behind the turret, via which auto-loader ammunition can be automatically supplied to the gun barrel. In order to achieve simplified automatic loading of the gun barrel with ammunition, the auto-loader is replaceably secured on the outside of the turret as a separate, modular unit. A magazine located in the auto-loader for receiving the ammunition can also be designed as an interchangeable magazine that can be replaced. An electronic system of the auto-loader is housed in the vehicle, specifically in the turret. The selection of ammunition in the auto-loader and the conveying out of the auto-loader are carried out via at least one mechanical interface, e.g. a power take-off, between the turret and the auto-loader.
