Derzeit tritt ein Problem beim Filtern der Rezensionen auf.

At the same time, the gas pressure pushes in the opposite direction, forcing the bolt backward. As in the recoil system, an extractor pulls the shell out of the barrel, and the ejector forces it out of the gun.

A new cartridge lines up in front of the bolt just before the spring pushes the bolt forward, starting the process all over again.

This continues as long as you hold the trigger down and there's ammunition feeding into the system.

Click and hold the trigger to see how a gas-action gun fires. The gas system is similar to the blowback system, but it has some additional pieces.

The main addition is a narrow piston attached to the bolt, which slides back and forth in a cylinder positioned above the gun barrel.

You can see how this system works in the diagram below. This gun is basically the same as one using the blowback system, but the rear force of the explosion doesn't propel the bolt backward.

Instead, the forward gas pressure pushes the bolt back. When the bolt swings forward to fire a cartridge, it locks onto the barrel.

Once the bullet makes its way down the barrel, the expanding gases can bleed into the cylinder above the barrel. This gas pressure pushes the piston backward, moving it along the bottom of the bolt.

The sliding piston first unlocks the bolt from the barrel, and then pushes the bolt back so a new cartridge can enter the breech.

The diagrams we've presented only depict particular examples of how these systems work. There are hundreds of machine gun models in existence, each with its own specific firing mechanism.

These guns differ in a number of other ways as well. In the next two sections, we'll look at some of the key differences between various machine gun models.

One of the main differences between different machine gun models is the loading mechanism. The early manual machine guns, such as the Gatling gun, used a device called the ammunition hopper.

Hoppers are just metal boxes containing loose individual cartridges that fit on top of the machine gun mechanism. One by one, the cartridges fall out of the hopper and into the breech.

Hoppers can hold a good amount of ammunition and they're easy to reload even while the gun is firing, but they are fairly cumbersome and only work if the gun is positioned right side up.

The hopper system was replaced by the belt-fed system , which helps control the ammunition's movement into the gun.

Ammunition is contained on a long belt, which the operator holds, or is contained in a bag or box. After a round is fired, it moves out of the way, and a new round slips into place.

Another system is the spring-operated magazine. In this system, a spring pushes cartridges in a magazine casing up into the breech.

The main advantages of this mechanism are that it's reliable, lightweight and easy to use. The main disadvantage is that it can only hold a relatively small amount of ammunition.

Heavy belt-fed machine guns, usually mounted on a tripod or a vehicle, may need more than one operator. Individual troops usually carry light weapons, with extendible bipods or tripods for stability.

Smaller automatic guns that use cartridge magazines are classified as automatic rifles, assault rifles or submachine guns. In a general sense, the term "machine gun" describes all automatic weapons, including these smaller weapons, but it's also used to describe heavy belt-fed guns specifically.

For sheer volume of ammunition, the belt system is usually the best option. Ammunition belts consist of a long string of cartridges fastened together with pieces of canvas or, more often, attached by small metal links.

Guns that use this sort of ammo have a feed mechanism driven by the recoil motion of the bolt. The bolt 1 in this gun has a small cam roller 5 on top of it.

As the bolt moves, the cam roller slides back and forth in a long, grooved feed cam piece 2. When the cam roller slides forward, it pushes the feed cam to the right against a return spring 6.

When the cam roller slides backward, the spring pushes the cam back to the left. The feed cam lever is attached to a spring-loaded pawl 8 , a curved gripper that rests on top of the ammunition belt.

As the cam and lever move, the pawl moves out, grabs onto a cartridge and pulls the belt through the gun.

When the bolt moves forward, it pushes the next cartridge into the chamber. The feed system drives the ammunition belt through cartridge guides 2 just above the breech.

As the bolt slides forward, the top of it pushes on the next cartridge in line. This drives the cartridge out of the belt, against the chambering ramp 3.

The chambering ramp forces the cartridge down in front of the bolt. The bolt has a small extractor, which grips the base of the cartridge shell when the cartridge slides into place.

As the cartridge slides in front of the bolt, it depresses the spring-loaded ejector 6. When the firing pin hits the primer, propelling the bullet down the barrel, the explosive force drives the operating rod and attached bolt backward.

When the shell clears the chamber wall, the ejector springs forward, popping the shell out of the gun through the ejection port.

This system lets you fire continuously without reloading. The basic mechanism of the machine gun has remained the same for more than a hundred years, but gun manufacturers are continually adding new modifications.

One modern design transforms from a box to a gun with the single push of a button [source: Sofge ]. In addition, new lightweight small arms technologies LSAT are made of lighter materials that could reduce the weight of machine guns and their ammunition by 40 percent.

Whether or not you've ever held a machine gun or even seen one, this powerful device has had a profound effect on your life.

Machine guns have had a hand in dissolving nations, repressing revolutions, overthrowing governments and ending wars.

In no uncertain terms, the machine gun is one of the most important military developments in the history of man. For additional information about machine guns and related topics, head to the links on the following page.

Machine guns changed warfare forever, but they run on basic concepts. See more gun pictures. Ballistic Background: Barrel.

Medium machine guns such as this one are an essential element in the modern arsenal. This depends purely on the weather conditions also, but in general it has proven by many soldiers at war to have conducted its duty of constant fixed positioned fire for long sessions at a time.

The M60 serves best its role to provide firepower support of bullet rain to infantry teams upon request of this during war.

The overall unique and unusual weaponry design of the modern F is somewhat the selling factor of what makes it highly favored in the firearm markets nowadays.

The great thing about its handling is that the material it is made from is incorporated with polymers which makes it extremely lighter than the rest of the heavy machine guns made of full metal and alloy.

FN F is best suited for both those who are left-handed and right handed and accommodates for ALL types of handlers. This idea of having a weapon that can be further refined to suit certain missions is going to be the advancement and success of future wars or missions so the we owe most of the success in the production of the FN F to its design.

The gun has its name for providing the same ground tripod or bipod ability as the M60, however with a narrowed down advantage of it being lighter in weight which makes it possible to run around with.

Many best machine guns or firearms in general have been downsized, chopped, changed, tried and tested over the years in order to accommodate and to be suited preference to a specific exclusive issued group such as the United States Military and U.

S corps etc. The M24E6 is one considerable example of the upgrades in weaponry over the years and in this case commonly known for its light weight yet with the same capabilities of providing precision shots and accuracy because of the stability the mounted bipod or tripod offers.

The mounted stability allows for changeable positions from one vantage point to the next without having to carry the pods as it will be fixated on the gun itself and in the same way is easier to carry and makes it faster to maneuver around with.

The M24E6 has also proven to more reliable, faster in rate of fire per minute and superior than the heavy old M The most notable features of the M can be revealed in the adjustable sights, the ergonomically designed carrying handle and the durability of the titanium steel used to produce the gun.

The great advantage of titanium steel will prevent rust from entering the usable and important parts of the firearm which ensures that the machine gun will work for more than its expected lifetime as rust is the main problem of jamming and barrel displacement in other guns we know today.

We see this gun, we run, we hear of this gun, we shudder and shiver in our spine. Just imagine the terror one would feel being held up in an extreme hostage situation with one of these?

In it was also a standard issue of weaponry and more especially a prized jewel to Joseph Stalin of that Era as it was most certainly the next best thing on the markets and to have been the stepping stone to all of his dangerous endeavors.

AK boasts an estimated million in production around the globe and these are only legal patented and produced, not forgetting the somewhat undetectable illegal production of these hand driven most powerful machine guns as well as backyard produced ammunition made by gun enthusiasts by melting and refining precious metals and putting together the parts of the AK in bulk productions and distributed all over the black markets.

This should tell you something about the remarkability and world phenomena of the revolutionary world popular AK Kalashnikov.

The sole purpose of a gun being in the form of a semi- automatic machine is purely to contribute to and to aid in ensuring the greater intended destruction that the licensed, authorized or issued users of this powerful artillery are getting for whatever purpose of use.

When we speak of an M4 Carbine Commando, picture a mercenary like Chuck Norris the movie: Missing in Action Holding this gun, getting ready to trail blaze a fire path of explosions and drilling the air with continuous hellfire.

This backup unit is a separate attachment which is the M under barrel mounted grenade launcher that was designed to fit as the main feature of this hand held monster.

The most effective position for guns in a single-seater fighter was clearly, for the purpose of aiming, directly in front of the pilot; but this placement would obviously result in bullets striking the moving propeller.

Early solutions, aside from simply hoping that luck was on the pilot's side with an unsynchronized forward-firing gun, involved either aircraft with pusher props like the Vickers F.

By mid , the introduction of a reliable gun synchronizer by the Imperial German Flying Corps made it possible to fire a closed-bolt machine gun forward through a spinning propeller by timing the firing of the gun to miss the blades.

The Allies had no equivalent system until and their aircraft suffered badly as a result, a period known as the Fokker Scourge , after the Fokker Eindecker , the first German plane to incorporate the new technology.

As better materials became available following the First World War, light machine guns became more readily portable; designs such as the Bren light machine gun replaced bulky predecessors like the Lewis gun in the squad support weapon role, while the modern division between medium machine guns like the M Browning machine gun and heavy machine guns like the Browning M2 became clearer.

New designs largely abandoned water jacket cooling systems as both undesirable, due to a greater emphasis on mobile tactics and unnecessary, thanks to the alternative and superior technique of preventing overheating by swapping barrels.

The interwar years also produced the first widely used and successful general-purpose machine gun , the German MG While this machine gun was equally able in the light and medium roles, it proved difficult to manufacture in quantity, and experts on industrial metalworking were called in to redesign the weapon for modern tooling, creating the MG This weapon was simpler, cheaper to produce, fired faster, and replaced the MG 34 in every application except vehicle mounts, since the MG 42's barrel changing system could not be operated when it was mounted.

Experience with the MG42 led to the US issuing a requirement to replace the aging Browning Automatic Rifle with a similar weapon, which would also replace the M; simply using the MG42 itself was not possible, as the design brief required a weapon which could be fired from the hip or shoulder like the BAR.

The resulting design, the M60 machine gun , was issued to troops during the Vietnam War. The most common interface on machine guns is a pistol grip and trigger.

On earlier manual machine guns, the most common type was a hand crank. On externally powered machine guns, such as miniguns, an electronic button or trigger on a joystick is commonly used.

Light machine guns often have a butt stock attached, while vehicle and tripod mounted machine guns usually have spade grips.

In the late 20th century, scopes and other complex optics became more common as opposed to the more basic iron sights. Loading systems in early manual machine guns were often from a hopper of loose un-linked cartridges.

Manual-operated volley guns usually had to be reloaded manually all at once each barrel reloaded by hand, or with a set of cartridges affixed to a plate that was inserted into the weapon.

With hoppers, the rounds could often be added while the weapon was firing. This gradually changed to belt-fed types.

Belts were either held in the open by the person, or in a bag or box. Some modern vehicle machine guns used linkless feed systems however.

Modern machine guns are commonly mounted in one of four ways. The first is a bipod — often these are integrated with the weapon. This is common on light machine guns and some medium machine guns.

Another is a tripod , where the person holding it does not form a "leg" of support. Medium and heavy machine guns usually use tripods.

On ships, vehicles and aircraft machine guns are usually mounted on a pintle mount — basically a steel post that is connected to the frame or body.

Tripod and pintle mounts are usually used with spade grips. The last major mounting type is one that is disconnected from humans, as part of an armament system, such as a tank coaxial or part of an aircraft's armament.

These are usually electrically fired and have complex sighting systems, for example, the US Helicopter Armament Subsystems.

Hotchkiss M machine Tv Stick Netflix. Vickers K machine gun VGO. Advances in metallurgy and use of special composites in barrel liners have allowed for greater heat absorption and dissipation during firing. In the first mention of the automatic principle of machine guns Transformers 3 in a paper presented to the Royal Society of Machine Gun by an Englishman by the name Eastgate Kino Palmer who described a volley gun capable of being operated by either recoil or gas. Some machine guns have in practice sustained fire almost continuously for hours; other automatic weapons overheat after less than a minute of use.

Machine guns are controlled by one or more mechanical sears. When a sear is in place, it effectively stops the bolt at some point in its range of motion.

Some sears stop the bolt when it is locked to the rear. Other sears stop the firing pin from going forward after the round is locked into the chamber.

Almost all machine guns have a "safety" sear , [ citation needed ] which simply keeps the trigger from engaging. The first successful machine-gun designs were developed in the midth century.

The key characteristic of modern machine guns, their relatively high rate of fire and more importantly mechanical loading, [3] first appeared in the Model Gatling gun , which was adopted by the United States Navy.

These weapons were still powered by hand; however, this changed with Hiram Maxim 's idea of harnessing recoil energy to power reloading in his Maxim machine gun.

Gatling also experimented with electric-motor-powered models; as discussed above, this externally powered machine reloading has seen use in modern weapons as well.

While technical use of the term "machine gun" has varied, the modern definition used by the Sporting Arms and Ammunition Manufacturers' Institute of America is "a fully automatic firearm that loads, fires and ejects continuously when the trigger is held to the rear until the ammunition is exhausted or pressure on the trigger is released.

The first known ancestors of multi-shot weapons were medieval organ guns , while the first to have the ability to fire multiple shots from a single barrel without a full manual reload were revolvers made in Europe in the late s.

One is a shoulder-gun-length weapon made in Nuremberg, Germany, circa Another is a revolving arquebus , produced by Hans Stopler of Nuremberg in True repeating long arms were difficult to manufacture prior to the development of the unitary firearm cartridge; nevertheless, lever-action repeating rifles such as the Kalthoff repeater and Cookson repeater were made in small quantities in the 17th century.

Perhaps the earliest examples of predecessors to the modern machine gun are to be found in East Asia. According to the Wu-Pei-Chih, a booklet examining Chinese military equipment produced during the first quarter of the 17th century, the Chinese army had in its arsenal the 'Po-Tzu Lien-Chu-P'ao' or 'string-ofbullets cannon'.

This was a repeating cannon fed by a hopper which fired its charges sequentially. This weapon was also hopper-fed and never went into mass production.

In the first mention of the automatic principle of machine guns was in a paper presented to the Royal Society of England by an Englishman by the name of Palmer who described a volley gun capable of being operated by either recoil or gas.

Another early revolving gun was created by James Puckle , a London lawyer, who patented what he called "The Puckle Gun " on May 15, It was a design for a manually operated 1.

According to Puckle, it was able to fire round bullets at Christians and square bullets at Turks. In , Philadelphia gunsmith Joseph Belton offered the Continental Congress a "new improved gun" , which was capable of firing up to twenty shots in five seconds; unlike older repeaters using complex lever-action mechanisms, it used a simpler system of superposed loads , and was loaded with a single large paper cartridge.

Congress requested that Belton modify flintlock muskets to fire eight shots in this manner, but rescinded the order when Belton's price proved too high.

In the early and midth century, a number of rapid-firing weapons appeared which offered multi-shot fire, mostly volley guns.

Volley guns such as the Mitrailleuse and double-barreled pistols relied on duplicating all parts of the gun, though the Nock gun used the otherwise-undesirable "chain fire" phenomenon where multiple chambers are ignited at once to propagate a spark from a single flintlock mechanism to multiple barrels.

Pepperbox pistols also did away with needing multiple hammers but used multiple manually operated barrels. Revolvers further reduced this to only needing a pre-prepared cylinder and linked advancing the cylinder to cocking the hammer.

However, these were still manually operated. In a machine capable of firing rifle shots a minute was devised by a French mechanic by the name of Hamel.

In the s a machine gun was designed by a Swiss man called Jacob Steuble, who tried to sell it to the Russian, English and French governments.

The English and Russian governments showed interest but the former refused to pay Steuble, who later sued them for this transgression, and the latter tried to imprison him.

The French government showed interest at first and while they noted that mechanically there was nothing wrong with Steuble's invention they turned him down, stating that the machine both lacked novelty and could not be usefully employed by the army.

In a short description of a prototype electrically-ignited mechanical machine gun was published in Scientific American by a J.

The model described is small in scale and works by rotating a series of barrels vertically so that it is feeding at the top from a 'tube' or hopper and could be discharged immediately at any elevation after having received a charge, according to the author.

In an Italian by the name of Cesar Rosaglio announced his invention of a machine gun capable of being operated by a single man and firing rifle shots a minute or 12, in an hour after taking into account the time needed to reload the 'tanks' of ammunition.

In June a model of a 'war engine' allegedly capable of firing 10, ball cartridges in 10 minutes was demonstrated by a British inventor called Francis McGetrick.

In a rotary cannon using a unique form of wheellock ignition was designed by an Irish immigrant to America by the name of Delany. In a British patent for a mechanically operated machine gun was filed by Henry Clarke.

This weapon used multiple barrels arranged side by side, fed by a revolving cylinder that was in turn fed by hoppers, similar to the system used by Nichols.

The gun could be fired by percussion or electricity, according to the author. Unlike other mechanically operated machine guns of the era, this weapon didn't use any form of self-contained cartridge, with firing being carried out by separate percussion caps.

In his patent, Bessemer describes a hydropneumatic delayed-blowback-operated, fully automatic cannon. Part of the patent also refers to a steam-operated piston to be used with firearms but the bulk of the patent is spent detailing the former system.

In America, a patent for a machine gun type weapon was filed by John Andrus Reynolds in Barnes in In France and Britain, a mechanically operated machine gun was patented in by the Frenchman Francois Julien.

This weapon was a cannon that fed from a type of open-ended tubular magazine, only using rollers and an endless chain in place of springs.

The Agar Gun , otherwise known as a "coffee-mill gun" because of its resemblance to a coffee mill, was invented by Wilson Agar at the beginning of the US Civil War.

The weapon featured mechanized loading using a hand crank linked to a hopper above the weapon. The weapon featured a single barrel and fired through the turning of the same crank; it operated using paper cartridges fitted with percussion caps and inserted into metal tubes which acted as chambers; it was therefore functionally similar to a revolver.

The weapon was demonstrated to President Lincoln in The Union Army eventually purchased a total of 54 of the weapons. However, due to antiquated views of the Ordnance Department the weapons, like its more famous counterpart the Gatling Gun, saw only limited use.

The Gatling gun , patented in by Richard Jordan Gatling , was the first to offer controlled, sequential fire with mechanical loading.

The design's key features were machine loading of prepared cartridges and a hand-operated crank for sequential high-speed firing.

It first saw very limited action in the American Civil War ; it was subsequently improved and used in the Franco-Prussian war and North-West Rebellion.

Many were sold to other armies in the late 19th century and continued to be used into the early 20th century, until they were gradually supplanted by Maxim guns.

Early multi-barrel guns were approximately the size and weight of contemporary artillery pieces, and were often perceived as a replacement for cannon firing grapeshot or canister shot.

In in the aftermath of the Second Schleswig War Denmark started a program intended to develop a gun that used the recoil of a fired shot to reload the firearm though a working model wouldn't be produced until In a Lt.

Friberg of the Swedish army patented a fully automatic recoil-operated firearm action and may have produced firing prototypes of a derived design around this was the forerunner to the Kjellman machine gun , though, due to rapid residue buildup from the use of black powder, Friberg's design was not a practical weapon.

Also in , the Bavarian regiment of the Prussian army used a unique mitrailleuse style weapon in the Franco-Prussian war. The weapon was made up of four barrels placed side by side that replaced the manual loading of the French mitrailleuse with a mechanical loading system featuring a hopper containing 41 cartridges at the breech of each barrel.

Although it was used effectively at times, mechanical difficulties hindered its operation and it was ultimately abandoned shortly after the war ended de.

The first practical self-powered machine gun was invented in by Sir Hiram Maxim. The Maxim machine gun used the recoil power of the previously fired bullet to reload rather than being hand-powered, enabling a much higher rate of fire than was possible using earlier designs such as the Nordenfelt and Gatling weapons.

Maxim also introduced the use of water cooling, via a water jacket around the barrel, to reduce overheating. Maxim's gun was widely adopted, and derivative designs were used on all sides during the First World War.

The design required fewer crew and was lighter and more usable than the Nordenfelt and Gatling guns. First World War combat experience demonstrated the military importance of the machine gun.

The United States Army issued four machine guns per regiment in , but that allowance increased to machine guns per regiment by Heavy guns based on the Maxim such as the Vickers machine gun were joined by many other machine weapons, which mostly had their start in the early 20th century such as the Hotchkiss machine gun.

Submachine guns e. The biggest single cause of casualties in World War I was actually artillery, but combined with wire entanglements , machine guns earned a fearsome reputation.

Another fundamental development occurring before and during the war was the incorporation by gun designers of machine gun auto-loading mechanisms into handguns, giving rise to semi-automatic pistols such as the Borchardt s , automatic machine pistols and later submachine guns such as the Beretta Aircraft-mounted machine guns were first used in combat in World War I.

Immediately this raised a fundamental problem. The most effective position for guns in a single-seater fighter was clearly, for the purpose of aiming, directly in front of the pilot; but this placement would obviously result in bullets striking the moving propeller.

Early solutions, aside from simply hoping that luck was on the pilot's side with an unsynchronized forward-firing gun, involved either aircraft with pusher props like the Vickers F.

Since then, innovations such as sheet-metal bodies and air-cooled, quick-changing barrels have made machine guns lighter and more reliable and quick-firing, but they still operate under the same principles as in the days of Hiram Maxim.

Most machine guns employ the gas generated by the explosion of the cartridge to drive the mechanism that introduces the new round in the chamber.

The machine gun thus requires no outside source of power, instead using the energy released by the burning propellant in a cartridge to feed, load, lock, and fire each round and to extract and eject the empty cartridge case.

This automatic operation may be accomplished by any of three ways: blowback , recoil, and gas operation. In recoil operation, the bolt is locked to the barrel immediately after a round is fired; both the bolt and barrel recoil, but the barrel is then returned forward by its own spring while the bolt is held to the rear by the locking mechanism until a fresh round has fallen into place in the opened breech.

More common than either of these two methods is gas operation. In this method, the energy required to operate the gun is obtained from the pressure of gas tapped off from the barrel after each cartridge explodes.

In a typical gas-operated machine gun, an opening or port is provided in the side of the barrel at a point somewhere between the breech and the muzzle.

When the bullet has passed this opening, some of the high-pressure gases behind it are tapped off through the hole and operate a piston or some similar device for converting the pressure of the powder gases to a thrust.

This thrust is then used through a suitable mechanism to provide the energy necessary for performing the automatic functions required for sustained fire: loading, firing, and ejection.
