Its use in combat in the Franco-Prussian war did not give conclusive results, especially compared to the Prussian firearm artillery pieces, entirely forged in steel and of a clearly superior effect.

In 1884, the first authentic machine gun appeared, the Maxim invented by the British nationalized American Hiram Maxim, who used the exhaust pressure of the firing gases to cause the recoil of the barrel, the opening of the bolt, the expulsion of the cap and the feeding with Another new cartridge obtained from a tape on the side of the weapon.

Maxim held demonstrations throughout Europe and his machine gun was adopted by most of the continent's armies. In 1885, the designer, inventor and manufacturer John Browning presents in the United States a model of machine gun powered by gas that is collected from the barrel through a piston inside a tube connected to the barrel of the weapon, a system adopted later for rifles Semi-automatic and assault.
