He raises his gas-operated AK-47 and presses a selector switch in the weapon, turning it fully automatic.
It and all other hand-operated machine guns were made obsolete by the development of recoil- and gas-operated guns that followed the invention of smokeless gunpowder.
All were gas-operated and magazine-fed and weighed from slightly over 20 pounds to more than 30 pounds loaded.
The Soviet 12.7-millimetre weapon, the Degtyarov-Shpagin Krupnokaliberny 1938 (DShK-38), was similar, but it was gas-operated.

Another gun from the Hotchkiss factory, the Hotchkiss Model 1914, was one of the first gas-operated, air-cooled machine guns.
The M16 is gas-operated and, in its original configuration, had both semiautomatic (i.e., autoloading) and fully automatic fire-control options.
