A device for transferring ammunition from a magazine to a transfer arm of an adjustable weapon rotatable about a trunnion. The transfer arm is movable together with the weapon and tilts up to a maximum predetermined angle (.beta.') during azimuth adjustment of the weapon. Two angle compensating elements are rotatable relative to one another about a common axis in planes that are inclined by half the predetermined angle (.beta.'/2) and are operatively disposed adjacent the magazine. A planar turntable is rotatably mounted on the two angle compensating elements for rotation relative thereto about the common axis. The plane of the planar turntable is adjusted by the two angle compensating elements. An ammunition receiving and pivoting device is supported on the turntable for receiving ammunition from the magazine and pivoting the ammunition so that the ammunition can be received by the transfer arm of the weapon.
