The magazine has inwardly flared flanges spaced beneath the lower extent of the side and front and rear faces. A base plate assembly has a base plate and a retainer. The base plate has essentially parallel side edges, a rear edge and a front edge with a circular aperture. The retainer has essentially parallel side edges, a rear edge and a front edge.
