With a mass of only 44.5 pounds (20 kg), it was the only complete machine gun at the time that could be carried by one man. In 1895, in response to the interest shown in the 40 pounds, air-cooled Colt-Browning M1895 ( Potato Digger ) in the U.S. machine gun trials, Hiram Maxim introduced his own air-cooled Extra Light gun weighing only 27 ...
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). [2] It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.
The XM301 is a lightweight, three-barrel version of the M61 Vulcan.It is externally powered, relying on the same power delivery system as the Vulcan. It fires M50 and PGU-series ammunition found in the Vulcan, as well as newer lightweight X1031/1032 aluminum-cased ammunition at either 750 or 1,500 rounds per minute. [2]
The innovative features of the Gatling gun were its independent firing mechanism for each barrel and the simultaneous action of the locks, barrels, carrier, and breech. The ammunition that Gatling eventually implemented was a paper cartridge charged with black powder and primed with a percussion cap because self-contained brass cartridges were ...
The original use of the recoil booster was to provide additional energy to move the large barrel/bolt mass on recoil operated machine guns. [7] At the start of WWI the primary German machine gun was the Maxim-based MG 08, a water-cooled heavy machine gun equipped with a blank firing adapter but not a muzzle booster.
The weapon combines two barrels into a single mechanism so that the recoil from firing one barrel loads and charges the second. Ammunition feeds into the gun from two vertically mounted cylindrical drums, one on each side. The drums held 180 rounds of German 7.92 mm rifle ammunition, feeding them into the breech using a compressed spring.
