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.
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 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.
A female worker boring out the barrel of a Lee-Enfield rifle during WWI. Gun barrels are usually made of some type of metal or metal alloy.However, during the late Tang dynasty, Chinese inventors discovered gunpowder, and used bamboo, which has a strong, naturally tubular stalk and is cheaper to obtain and process, as the first barrels in gunpowder projectile weapons such as fire lances.

A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
The armour-piercing gun evolution has also shown up in small arms, particularly the now abandoned U.S. Advanced Combat Rifle (ACR) program. The ACR "rifles" used smoothbore barrels to fire single or multiple flechettes (tiny darts), rather than bullets, per pull of the trigger, to provide long range, flat trajectory, and armor-piercing abilities.
A general-purpose machine gun is usually a lightweight medium machine gun that can either be used with a bipod and drum in the light machine gun role or a tripod and belt feed in the medium machine gun role. DShK in the heavy role. Machine guns usually have simple iron sights, though the use of optics is becoming more common.
The mounting of the barrel can also have a significant effect on the motion of the barrel when it is fired. In a tank gun the mounting is normally in a structure called the 'cradle' which is supported in bearings usually referred to as trunnions which enable elevation of the gun. Mountings of other gun systems can vary considerably, but in all ...
