A plurality of magazine retaining members are also included each having a portion inserted into a portion of the lateral drive portion, and each having a cavity wherein a base portion of a corresponding one of the magazines rests. The lateral drive portion comprises a multi-pitch threaded shaft, a single motor coupled to the shaft for selectively rotating the shaft in either a clockwise or a counterclockwise direction, and a housing fitting over a portion of the shaft and having an aperture through a top surface portion thereof.
