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 MG 338 is fully ambidextrous and is capable of being fed and charged from the right or left side which can make mounting the machine gun to various vehicles easier. [4] It can also be loaded from the closed or open bolt position. [2] [5] Standard configuration uses an AR style handgrip and folding buttstock. [2]
In a stationary, heavy machine gun role the MG5 can also be mounted on the MG3 Feldlafette buffered field tripod by using additional adapters. The Bundeswehr use a RAL 8000 green brown surface finish on their MG5s and has chosen to use a 550 mm (21.7 in) barrel instead of a 663 mm (26.1 in) barrel for their mounted guns to promote parts uniformity.
The Bangerter machine gun uses a blow-forward operation and is the most complex example. The Slostin machine gun uses a similar operation but with gas pistons on each barrels. The GShG-7.62 machine gun and GSh-6-23, both use a more effective, simpler gas piston drive in the center of the barrel cluster.
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 ...
In fact, it was a process created specifically to extend the life of gun barrels by reducing the effects of wear. Cold-hammer forged machine gun barrels were mass-produced during World War II for the air-cooled MG 42 general-purpose machine gun which very high 1,200 to 1,500 rounds-per-minute cyclic fire rate imparted significant heat stress ...
The RMG 7.62 is a development of the MG3, intended as a vehicle mounted weapon where changing the overheated barrel would be a problem.Like the MG3, it is a recoil operated weapon that fires at about 800rpm and uses the belt feed from the MG3.
