Abstract
A dual ammunition feed for automatic weapons includes a positioning device for the ammunition wherein a central positioning sprocket unit interacts with two feed sprocket units in two separate feed casings to allow for loading with two different types of ammunition. The feed casings are tiltable into and out of engagement with the positioning device, the tilting of a particular feed casing into engagement with the positioning device being followed by the simultaneous disengagement of the other feed casing from the positioning device. The tilting of a particular feed casing into engagement further results in the coupling of the engaged feed casing's feed sprocket unit with a reducing transmission driven by an external motor, and in a change in the rotational direction of the central positioning sprocket unit such that the central positioning sprocket unit always rotates in an opposite direction from that of the feed sprocket unit of the particular feed casing which is engaged.
