ドライゼ銃
Firearms with rifled barrels existed long before the 19th century but did not become widely used before the end of the American Civil War. Thus, rifles in the early 19th century were for specialist marksmen only, whilst ordinary infantry were issued less accurate smoothbore muskets which had a higher rate of fire, with bore diameters as high as 19 mm (0.75 inch). Early "service rifles" of the 1840s, such as the Prussian Dreyse needle gun (1841) and the Swiss Infanteriegewehr Modell 1842, were technically still muskets.
