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.

A number of embodiments of a firearm are disclosed where the firearm includes a magazine configured to hold the bolt in an open position when the magazine is empty. In one embodiment, the firearm includes a bolt stop mechanism that moves between a first position where it allows the bolt to cycle between an open position and a closed position and a second position where it holds the bolt in the open position. The magazine is configured to actuate the bolt stop mechanism to the first position when the magazine is empty.

An automatic or semiautomatic rifle having a short-stroke action with multiple firing chambers which are arranged radially around an axis of rotation parallel to the firing bore. The multiple firing chambers reciprocate rearward and forward while the assembly is indexed through a loading, firing, and ejection sequence. Ammunition cartridges are inserted into the forward end of the chambers and subsequently positioned against the rear of a barrel of the rifle for firing.
