The Colt–Browning M1895, nicknamed "potato digger" because of its unusual operating mechanism, is an air-cooled, belt-fed, gas-operated machine gun that fires from a closed bolt with a cyclic rate of 450 rounds per minute. Based on an 1889 design by John Browning and his brother Matthew S. Browning, it was the first successful gas-operated machine gun to enter service.
