  • Figure 4 is a section along the line 4-4 of Figure 1. 6
  • the magazine has an outlet which should be avoided at all costs in automatic fire-arms.
  • the object of the present invention is to select for the magazine outlet a design eliminating the possibility for the cartridge to drop in front of the extractor claw under the efiect of the blow imparted to it by the breech block on its forward travel.
  • this object is secured by providing the front ends of the guiding ledges fitted at the magazine outlet for the cartridge to be fed-with two projections facing each other and encompassing the cartridge case.
  • the diameter of these projections is greater than the diameter of the cartridge case at its front end, so that the cartridge is able to glide on the guiding ledges; on the other hand it is smaller than the rear part of the tapered cartridge case.
  • the cartridge case impelled forward by the breech block on its forward travel is clamped between the two projections, and can only be forced out of the guiding lips by the elastic widening of the magazine bottom.
  • the guiding ledges facing each other are formed complemental to the shape of the cartridge and suitably encompass it above the middle aXis so as to make it impossible for the cartridge to escape upwards whilst the breech block is impelling it forward.
  • Figure 2 is a bottom plan of the same
