A toy gun which is capable of firing a plurality of elasticized bands, either singularly or in rapid succession, and which is operative so that each one of a plurality of elasticized bands is stretched under the tension of its own elasticity along a projectile path longitudinal with the gun between a point of anchorage at the forward end of the gun and a rotatable escapement wheel at the rearward end of the gun so that, when the escapement wheel is permitted to rotate under the influence of a rotational bias provided by the force of the previously loaded elasticized bands upon the release of a trigger mechanism, the elasticized bands are consecutively released from engagement with the escapement wheel to be propelled along the projectile path and forwardly of the gun. The wheel includes a plurality of spaced apart radially extending sections that have successively increasing radii over substantially the entire outer-most periphery of all of the sections.
