Breech for an automatic firearm

摘要

In such a breech for an automatic machine gun, whose breech body (7) has an extractor (10) for fixing the cartridge case (16) during its rearward movement, and has an ejector (17), a guide (22) is provided in the region of an ejection opening (18) for the cartridge case (16). This guide guides the cartridge case (16) during a part of the rearward movement of the breech body (7) in order to prevent said cartridge case (16) being positioned obliquely with respect to its movement direction after firing by being acted on by the gases which emerge from the firing chamber. <IMAGE>
