The Breda M30 or Breda 30, was rather unusual for a light machine gun. It was fed from a fixed magazine attached to the right side of the weapon and was loaded using brass or steel 20-round stripper clips. If the magazine or its hinge/latch were damaged the weapon became unusable. It also fired from a closed bolt along with using blowback for its action. The blowback operation was violent, and often resulted in poor primary extraction. During primary extraction, the initial very small rearward movement of the hot expanded cartridge case away from the chamber's walls must be powerful but very slow, if an automatic weapon is to be reliable. Separated cases resulting in jamming of the weapon beyond field clearing, were usually the consequence of poor primary extraction. Breda 30 also inherently lacked good primary extraction in its design and thus utilized a small lubrication device that oiled each cartridge as it entered the chamber. With the dust and sand of the deserts of North Africa, came a combination of premature wear and jamming.
