Volley gun
The Ribauldequin was a medieval version of the volley gun. It had its barrels set up in parallel. This early version was first employed during the Hundred Years' War by the army of Edward III of England, in 1339. Later on, the late Swiss army employed it.
German military rifles
The Dreyse needle-gun ("Nadelgewehr") was a military breechloading rifle, famous as the arm of the Prussians, who adopted it for service in 1848 as the Prussian Model 1848. Its name comes from its needle-like firing pin, which passed through the cartridge case to detonate a percussion cap at the base of the bullet. The Dreyse rifle was also the first breech-loading rifle to use a bolt-action to open and close the chamber.
