  • Patent number: 9719741
    Abstract: A magazine loading device comprises an ammunition delivery interface, a shuttle or escapement, an orientation gate, a staging gate, a plunger, and a magazine receiver. The ammunition may be supplied to the ammunition delivery interface in a number of ways, including utilization of a hopper. The ammunition may be guided into an opening in the shuttle or escapement, which may then transfer the ammunition to an orientation gate. The geometry of the orientation gate is such that the ammunition will always drop through the orientation gate with the projectile down, which in this case is the desired orientation for loading into the magazine. A plunger may then push the ammunition into the magazine.
