Gatling machine gun is a manual multi-barrel machine gun designed by American Richard jordan Gatling in1860s. It is the first practical machine gun. It was imported into China around 1874 (13th year of Tongzhi in Qing Dynasty), and was called Gatling machine gun at that time. Gatling machine gun is the most powerful gun, which can shoot 3000 bullets per minute after improvement. Maxim heavy machine gun, known as race electric gun in China, was invented by British and American Hiram Stevens Maxim in 1883, and its principle was tested, and it was patented in 1884. Maxim machine gun is the first truly successful automatic weapon powered by gunpowder and gas in the world. Its caliber is11.43mm, and the gun weighs 27.2kg.. Adopt automatic mode, short recoil (19 mm) and water-cooled barrel. The canvas belt with a capacity of 333 rounds and a weight of 6.4 meters Ma Keqin is used for ammunition replenishment, and the belt can be connected. The theoretical firing rate is 600 rounds/minute, and it can be fired in single or continuous bursts; It can also be adjusted to the slow firing rate of 100 rounds/minute through the firing rate regulator. Maxim machine gun has a complex structure, a huge water-cooled barrel, and the reliability of canvas belt becomes worse after it is wetted, but it has been widely used in modern wars. Therefore, gatling and Ma Keqin are two different machine guns, not the same one.
