Zbrojovka vz. 59 Special Machine Gun Of Ceska Zbrojovka Army
CZ-UB, or Ceska Zbrojovka - Uhersky Brod (literally "Czech Weapons Factory - Uhersky Brod") began life as a satellite plant of the original Ceska Zbrojovka enterprise, Ceska Zbrojovka, a.s., Praha, a joint-stock company that was partially nationalized in the late 1930s. CZ-UB was originally known as Ceska Zbrojovka, a.s., Praha, zavod v Uherskem Brode ("Czech Weapons Factory, joint-stock company of Prague, Plant at Uhersky Brod") from its inception in 1936 to 1945. However, the full story of the company we know as "CZ" begins at the birth of the Czechoslovak Republic, shortly after World War I.
The troubled history between the Czech and Slovak peoples and their German and Austrian "neighbors" motivated the Czechoslovak Republic to build a strong domestic military-industrial complex. The Czechoslovak nation was created by treaty in 1919; thus, it inherited many political and social problems from the Austro-Hungarian Empire that were simply ignored at Versailles. These included the artificial marriage of the Czech and Slovak lands, large numbers of German and Hungarian minorities in Bohemia, and relative political isolation. From a strategic standpoint, Czechoslovakia was surrounded on three sides by hostile neighbors and did not enjoy close relations with Poland and the Soviet Union. For these reasons, the rearmament and industrial development of Czechoslovakia were the primary economic and strategic goals of the young republic, and this process began almost immediately in 1919-1920. New enterprises were created for the production for ordnance, munitions, and arms, and most of these facilities still exist today, usually in the form of independent joint-stock companies. Ceska Zbrojovka-Uhersky Brod is considered the current incarnation of the original Ceska Zbrojovka, which began life in this period.
It is impossible to tell the story of Ceska Zbrojovka without first discussing Zbrojovka Brno. Officially founded in 1917, Zbrojovka Brno ("Weapons Factory of Brno") had played a small, but vital role in the first World War. Brno is the former capital of the Kingdom of Moravia, and it is also the second largest city in the Czech lands. The Brno arsenal would soon make a name for Czech firearms in the European civilian market, but the Brno plant lacked the overall capacity to rearm an entire nation. As the only major established arsenal, the renamed Ceskoslovenska Zbrojovka Brno tackled several high-priority projects in 1919-1920. These included the manufacture of railway rolling stock, design and manufacture of hand grenades, and the re-arsenaling of Austrian 8mm M-95 Mannlicher rifles. Beginning in 1921, Brno began manufacture of Mauser Gewehr 98 rifles, since German production was prevented by the Versailles Treaty. While this meant that Brno would be better known for most of the 20th century, it created a unique opportunity for the development of Ceska Zbrojovka.
The forerunner of CZ-UB was the enterprise Jihoceska Zbrojovka, which was established at Plzen in 1919. In 1921, Jihoceska Zbrojovka moved to Strakonice. In 1922, the company absorbed the Hubertus Company, which had facilities at Vejprty and Prague. At this time, the company was renamed Ceska Zbrojovka. By 1923, these facilities were known as Ceská Zbrojovka v Praze ("Czech Weapons Factory of Prague") and Ceská Zbrojovka v Praze, Továrny ve Strakonicích ("Czech Weapons Factory of Prague, Strakonice Plant"). Various firms in the Czechoslovak Republic and Western Europe supplied some of the necessary parts during this period.
During this early period, Jihoceska Zbrojovka/Ceska Zbrojovka production concentrated on the vz-22 pistol, a relatively complicated locked-breech design in .380 ACP (9x17mm, 9mm Browning Short). Essentially, the vz-22 was a pocket pistol intended for export, like the vast majority of European handguns of the post-war period. In 1924, the vz-24 replaced the vz-22. The vz-24 is little more than an improved and more elegant vz-22; it was also chambered in .380 ACP. The vz-24 was more popular than its forerunner in the civilian export market, and thus more common in the U.S. and Western Europe. During this period, the Czech military issued a wide variety of handguns, including Austro-Hungarian models and the vz-24.
By 1924, the general policy of the Czech arms industry emerged: Zbrojovka Brno would make bolt-action rifles and Ceska Zbrojovka would make virtually everything else (mostly pistols, machine guns, aircraft armament, and signal guns). With the notable exception of the vz-24 pistol, which was also exported, Ceska Zbrojovka focused on contracts for the Czechoslovak military and police from 1924-1938. During this period, production at Brno concentrated on the vz-24 Czech Mauser for the Czech military and export. The emphasis on export was intended to garner foreign currency for modernization of the Czech arms industry.
The Gun, Machine, Vickers, .5-inch, Mk. III was used as an anti-aircraft gun on British ships.
The weight of the gun itself varied based on the gear attached, but was generally 25-30 lb (11-13 kg), with a 40-50 lb (18-23 kg) tripod. The ammunition boxes for the 250-round ammunition belts weighed 22 lb (10 kg) each. In addition, it required about 7.5 imperial pints (4.3 L) of water in its evaporative cooling system to prevent overheating. The heat of the barrel boiled the water in the jacket surrounding it. The resulting steam was taken off by flexible tube to a condenser container—this had the dual benefits of avoiding giving away the gun's location, and also enabling re-use of the water, which was very important in arid environments.
Rimmed, centrefire Mk 7 .303 inch (7.7 mm) cartridge from World War II.
In British service, the Vickers gun fired the standard .303 inch (7.7 mm) cartridges used in the Lee Enfield rifle, which generally had to be hand-loaded into the cloth ammunition belts. There was also a 0.5 in (12.7 mm) calibre version used as an anti-aircraft weapon and various other calibres produced for foreign buyers. Some British tanks of the early Second World War were equipped with the 0.5 in (12.7 mm) Vickers.
The gun was 3 ft 8 in (1.1 m) long and its cyclic rate of fire was between 450 and 600 rounds per minute. In practice, it was expected that 10,000 rounds would be fired per hour, and that the barrel would be changed every hour—a two-minute job for a trained team. Firing the Mark 8 cartridge, which had a streamlined bullet, it could be used against targets at a range of approximately 4,500 yd (4.1 km).

Type 67 machine gun used by the Chinese People's Liberation Army Mechine Gun
The Type 67 is a 7.62 mm general purpose machine gun used by the Chinese People's Liberation Army. It shares some design features with the Soviet-built PK machine gun, but is a true hybrid of a number of different machine gun models, including both Soviet and Western designs that had been in Chinese military service at various times throughout the twentieth century. Since 1967 – the year of its introduction – the Type 67 has gone through two model modifications and improvements, with the newer models designated Type 67-1 and Type 67-2.
Sumitomo NTK 62 Japan Self Defense Force Mechine Gun
The T-62/NTK-62 is the standard issue GPMG of the Japan Self-Defense Forces. Known as the Type-62 GPMG, It is similar to the Belgian FN MAG, but not a variation of it. Though the Sumitomo Heavy Industries\' M249 had largely replaced it in the JGSDF, the weapon still plays a support role as it is still used as a co-axial weapon in various armored vehicles, including tanks and APCs, as well as being a medium support machine gun. Similar in application to the M60 Machine gun, it fires 7.62 mm NATO cartridges.
After years of using the Browning M1919A4 as its standard GPMG during the early days of founding the Japan Self Defense Forces, Sumitomo Heavy Industries had manufactured the NTK-62 GPMG, designed at Japan Special Steel (NTK) by Masaya Kawamura\'s team. The designation \"62\" was present due to the fact that first batches of the NTK-62 were made in the year 1962.
One can tell the NTK-62 from the FN MAG from the bipod, barrel, buttstock and pistol grip as these changes were possibly made to suit Japan Self Defense Forces guidelines and standards.
The Stoner 63/63A LMG is an automatic weapon that fires from the open bolt and the trigger Mechine Gun
The Stoner 63/63A is supplied with several accessories, including: a blank-firing attachment (BFA), winter trigger guard, asbestos-lined spare barrel bag, cleaning kit, 40 mm grenade launcher, several types of slings and a wide range of belt box and magazine pouches.
The Stoner 63/63A used three different types of bayonets: the standard U.S. M7, the KCB 70, developed specifically for this rifle by the West German company Eickhorn-Solingen together with NWM and a rare bayonet made by the Swiss industrial conglomerate SIG. The KCB 70 features a 7-inch (180 mm) long Bowie blade with a clip-point and an integrated wire-cutter, it was inspired by Soviet bayonets for the AKM. A highly successful multi-purpose tool that was a far superior field knife to the M7, it evolved into the KCB 77, a modular design that was adapted to many different assault rifles.
Austrian soldiers deployed with the Steyr AUG
The rifle features a two-stage trigger (pulling the trigger halfway produces semi-automatic fire, pulling the trigger all the way to the rear produces fully automatic fire) and a safety mechanism (cross-bolt, button type), located immediately above the hand grip. In its “safe” position (white dot) the trigger is mechanically disabled; pressing the safety button to the left exposes a red dot and indicates the weapon is ready to fire. Some versions have an ALO or "automatic lockout", a small projection at the base of the trigger. This was first included on the Irish Defence Forces variant of the rifle, and soon after, the Australian Defence Forces variant. In the exposed position the ALO stops the trigger being squeezed past the semi-automatic position. If needed, the ALO can be pushed up to permit automatic fire.
The rifle is fed from translucent, double-column box magazines (molded from a high-strength polymer) with a 30-round capacity and an empty weight of 130 g (4.6 oz). The light machine gun version of the AUG uses an extended 42-round magazine.
Integrated with the receiver casting is a fixed carry handle that contains a 1.5x telescopic sight made by Swarovski Optik. It contains a simple black ring reticle with a basic rangefinder that is designed so that at 300 m (984.3 ft) a 180 cm (5 ft 10.9 in) tall man-size target will completely fill ( subtend ) it, giving the shooter a relatively accurate method of estimating range. The sight cannot be set to a specific range but can be adjusted for windage and elevation for an initial zero and is designed to be calibrated for 300 m. When so set, aiming at the centre of a target will produce a hit at all ranges out to 300m. The rifle also has a back-up iron sight with a rear notch and front blade, cast into the top of the aluminum optical sight housing, used in case of failure or damage to the primary optical sight. The sight is also equipped with a set of three illuminated dots (one on the front blade and two at the rear) for use in low-level lighting conditions. In order to mount a wide range of optics and accessories, a receiver with a NATO-standard Picatinny rail and detachable carry handle was also developed and introduced in 1997.
Three-pronged, open-type flash suppressors were used on the 350 mm (13.8 in), 407 mm (16.0 in) and 508 mm (20.0 in) length barrels, whereas the 621 mm (24.4 in) light machine gun barrel received a closed-type ported muzzle device (combination flash suppressor and compensator) and an integral, lightweight folding bipod. The flash suppressors are screwed to the muzzle and internally threaded to take a blank-firing attachment.
The rifle comes standard with four magazines, a muzzle cap, spare bolt for left-handed shooters, blank-firing adaptor, cleaning kit, sling and either an American M7 or Austrian KCB bayonet.

The USSR ARMY Kalashnikov RPK light machine gun
The RPK has a new, heavier and extended barrel with an increased heat capacity. The chrome-lined barrel is permanently fixed to the receiver and cannot be replaced in the field. It is fitted with a new front sight base, gas block (lacks the bayonet lug) and an under-barrel cleaning rod guide. The barrel also features a folding bipod, mounted near the muzzle and a front sight base with a lug that limits the bipod's rotation around the barrel. The barrel's muzzle is threaded, enabling the use of a blank-firing adaptor. When the blank-firing attachment is not used, the threading is protected by a thread protector cap from the AK. The barrel is pinned to the receiver in a modified trunnion, reinforced by ribbing, and is slightly wider than the trunnion used in the AKM. Symmetrical bulges on both sides of the barrel chamber ensure proper fit inside the receiver.
The RPK receiver cover is stamped from a smooth 1.5 mm (0.1 in) sheet of steel (compared to only 1 mm sheet metal used in the AKM). Interchangeability of parts between the RPK and AKM is quite significant.
The RPK uses a different recoil mechanism as compared to the AKM, which consists of a rear spring guide rod from the AK, and a new forward flat guide rod and coil spring.
The RPK features a thicker wooden forearm, a fixed wooden buttstock shaped like the RPD stock, optimized for prone firing, and a pistol grip from the AKM.
The weapon is fed from box magazines with a 40-round capacity or a 75-round drum magazine, both are compatible with magazines used with the AK-47 and AKM series.
A pintle-mounted MG 3A1 on a Norwegian armoured vehicle. Wars snipers
The MG 3 is an automatic, air-cooled, belt-fed short recoil-operated firearm. It features a roller locked bolt mechanism that consists of the bolt head, a pair of rollers, the striker sleeve, bolt body and return spring. The bolt is locked securely by a wedge-like striker sleeve, which forces two cylindrical rollers contained in the bolt head outward, and into corresponding recesses in the extension of the breech of the barrel. On firing, both the barrel and barrel extension recoil to the rear compressing both rollers as they are cammed inward and out of their sockets by fixed cams, unlocking the bolt head. The bolt carrier and bolt then continue to the rear together guided by fixed guides while the barrel and barrel extension return to battery. Upon return of the bolt forward, the impact of the rollers against the camming surfaces on the breech carry the rollers from their seats, and, together with the surfaces on the striker sleeve, force the rollers outward, locking the bolt head into the barrel extension and ensuring a complete lock. The bolt also houses a spring-loaded casing extractor and ejector. Ejection is carried out when the ejector strikes the buffer head, sending a push forward through the ejector bar, which hits the ejector pin. This pin pushes the top of the base of the cartridge, which is still held by the extractor at the base, causing the empty casing to rotate and eject downward through the ejection chute.
The machine gun has an automatic-only trigger mechanism and a cross-bolt safety in the form of a button that is operated by the shooting hand (in its "safe" position the bolt release is disabled). The weapon fires from an open bolt.
The MG 3 feeds from the left side through a feed block using metal, 50-round continuous-link ammunition belts (which can be combined by cartridge) or disintegrating-link M13 or DM6 belts. In the light machine gun role, the DM1 MG 3 is deployed with a 100-round belt fitted inside a synthetic ammunition drum developed by Heckler & Koch that is latched on to the left side of the receiver. The rear wall of the drum is transparent and serves as a visual indicator for the amount of ammunition available. The feed system operates through a feed arm that is housed in the feed cover. Two feed pawls are linked to the front end of the arm by an intermediate link and move in opposite directions, moving the belt in two stages as the bolt moves back and forward during firing.
The MG 3 seen here in the stationary, heavy machine gun role, mounted on a stabilized Feldlafette tripod and fitted with an optical periscope sight.
The MG 3 has a quick-change, chrome-lined barrel with 4 right-hand grooves and a rifling twist rate of 1 in 305 mm (1:12 in). The barrel is integrated with the barrel breech. The barrel should be changed frequently during sustained firing. The gun is cocked and the barrel catch on the right of the barrel shroud is swung forward. The breech end of the hot barrel swings out and can be removed by elevating or twisting the gun. A fresh barrel is then inserted through the barrel catch and the muzzle bearing. When the catch is rotated back the barrel is locked and the machine gun can resume firing. Both the receiver housing and ventilated barrel casing are made from pressed sheet steel. A muzzle device is mounted at the end of the barrel and it acts as a flash suppressor, muzzle brake and recoil booster.
The machine gun is equipped with a synthetic polymer stock, a folding bipod and open-type iron sights (sliding rear U-notch on a ramp with range settings from 200 to 1,200 m). A flip-up anti-aircraft sight is also provided.
In a stationary, heavy machine gun role the MG 3 is mounted on a buffered tripod called a Feldlafette and outfitted with a periscope sight that can be used to engage indirect targets.
A 19th Special Forces Group soldier mans an M60 machine gun on a HMMWV in Afghanistan
The M60 is a belt-fed machine gun that fires the 7.62 mm NATO cartridge commonly used in larger rifles. It is generally used as crew-served weapon and operated by a team of two or three men. The team consists of the gunner, the assistant gunner (A-gunner in military slang), and the ammunition bearer. The gun's weight and the amount of ammunition it consumes when fired make it difficult for a single soldier to carry and operate. The gunner carries the weapon and, depending on his strength and stamina, anywhere from 200 to 1000 rounds of ammunition. The assistant carries a spare barrel and extra ammunition, and reloads and spots targets for the gunner. The ammunition bearer carries additional ammunition and the tripod with associated traversing and elevation mechanism, if issued, and fetches more ammunition as needed during firing.
Firing an M60 machine gun from the standing position during the DEFENDER CHALLENGE '88 competition
The basic ammunition load carried by the crew is 600 to 900 rounds and theoretically allows approximately two minutes of continuous firing at the maximum rate of fire. All crews carry more than the basic load, sometimes three or more times the basic amount.[citation needed]
The M60 can be accurately fired at short ranges from the shoulder due to its design. This was an initial requirement for the design and a hold-over in concept from the M1918 Browning Automatic Rifle. It may also be fired from the integral bipod, M122 tripod, and some other mounts.
M60 ammunition comes in a cloth bandolier containing a cardboard box of 100 pre-linked rounds. The M60 changed from M1 link to the different M13 link, a change from the older link system with which it was not compatible. The cloth bandoleer is reinforced to allow it to be hung from the current version of the feed tray. Historically, units in Vietnam used B3A cans from C-rations packs locked into the ammunition box attachment system to roll the ammunition belts over for a straighter and smoother feed to the loading port to enhance reliability of feed. The later models changed the ammunition box attachment point and made this adaptation not possible.

The IMI Negev is a light-weight, 5.56 mm calibre, belt-fed, bipod mounted, Israeli machine gun used as a squad assault weapon
The Negev is a gas-operated automatic firearm that uses propellant gases from the barrel to cycle a short-stroke gas piston operating system under the barrel and a rotary bolt locking mechanism. The bolt itself features 4 radial locking lugs that engage the barrel extension and its rotation is controlled by a pin on the bolt body, which rides inside a camming guide machined into the bolt carrier. The bolt contains a spring-powered casing extractor unit, while a lever ejector is housed inside the receiver (it is rotated by the recoiling bolt carrier).
The Negev’s adjustable gas regulator has three settings: “1” – used exclusively when feeding from a magazine (the weapon’s rate of fire in this mode is 850–1,150 rounds/min), setting “2” is used in normal operating conditions when feeding from a belt (rate of fire: 850–1,150 rounds/min) and setting “3” which is used under adverse operating conditions, such as in the presence of dust, dirt or heavy fouling (cyclic rate of fire is 950-1,150 rounds/min). Early prototypes used a different 3-position gas adjustment system: setting “1” – normal operation, setting “2” – for adverse environmental conditions and setting “3” – isolates the gas system, used to launch rifle grenades with the use of a grenade-launching blank cartridge drawn from a special 12-round magazine (from the Galil rifle).
The Negev is striker-fired, where the bolt carrier assembly acts as the striker. The light machine gun fires from an open bolt position. A lever-type fire control selector switch is provided (“A” – automatic fire, “R” – semi-automatic fire), installed on the left side of the pistol pistol grip, which doubles as a manual safety against accidental firing. The safe “S” position disables the sear mechanism (which makes it impossible to cock the bolt carrier), by lifting the lever responsible for holding the bolt carrier in the forward position and disconnects the trigger mechanism from the sear. The weapon can be secured safe regardless of the position of the bolt carrier group. The cocking handle is equipped with a ratcheting mechanism that immobilizes the partially-cocked bolt carrier.
The Negev feeds from an M27 disintegrating, open-link ammunition belt, carried in a 150-round fabric container that clips into the magazine well or alternately from a 35-round box magazine from the Galil assault rifle or a 30-round STANAG magazine from the M16 rifle (with the use of an adapter). 200-round ammunition belt containers are also available. Belted ammunition is introduced into the feed tray port from the left side, while the magazine is inserted vertically into the magazine well at the base of the receiver. The feed system uses a pawl feeding mechanism, driven by the recoiling bolt carrier, but the belt is only moved during the rearward movement of the bolt carrier. The non-reciprocating charging handle is located on the right side of the weapon.
The Negev has a quick-change chrome-lined barrel that is manufactured using a cold hammer forging process. The barrel is fitted with a slotted flash suppressor and a fixed carry handle, which is used to transport the weapon and change-out an overheated barrel. The barrel can only be changed after lifting open the feed tray cover.
During the weapon’s initial development a barrel with a 1 in 305 mm (1:12 in) rifling twist rate was also planned, adapted for the lightweight M193 cartridge. Additionally, a multifunction muzzle device was designed, used to launch rifle grenades.
The Negev’s iron sights (closed-type) consist of a front post (adjustable for both windage and elevation) and a rear aperture sight with an elevation adjustment drum, with 300 to 1,000 m range settings. For night-time operation the weapon is equipped with gaseous tritium-illuminated vials (supplied by Betalight): one installed in the front sight post, and two — on a notch sight under the standard aperture sight arm (before use, the rear sight leaf is pivoted forward to expose the night notch sight). A rail is integrated into the receiver top cover that allows optical day and night-time sights to be mounted to the weapon. The barrel can also be optionally fitted with mounting hardware that would allow the Negev to mount a laser pointer or reflex sight.
The machine gun has a metal side-folding (right side) stock and a removable bipod, installed to the forward end of the handguard and folded under the handguard when stowed. The receiver also has slots and hooks used to secure the weapon to vehicle mounting hardware.
The Negev uses the 5.56x45mm NATO cartridge and is optimized for the SS109 bullet. Field maintenance involves stripping the weapon down to six main groups: the barrel, stock, bolt carrier, bolt, bipod and return mechanism. All parts, including the quick-change barrels, are fully interchangeable.
FN Minimi - Belgian-made version of basic machine gun
The M249 is a belt-fed light machine gun. It fires the 5.56x45 mm NATO cartridge, usually a combination of one M856 tracer and four M855 ball cartridges fed from M27 linked belts. Belts are typically held in a hard plastic or soft canvas box attached to the underside of the weapon.
It fires from an open bolt and is gas operated. When the trigger is pulled, the bolt and bolt carrier move forward under the power of the recoil spring. A cartridge is stripped from the belt, chambered, and discharged, sending a bullet down the bore. Expanding propellant gases are diverted through a hole in the barrel into a chamber. This pressure moves a piston providing the energy to extract and eject the spent casing as well as advance the belt and compress the recoil spring, thus preparing for subsequent shots. At 1,041 mm (41 in) long and 7.5 kg (17 lb) in weight (10 kg (22 lb) including a 200-round belt and plastic ammo box), the M249 is a cumbersome weapon.
The barrel has a rifling twist rate of one turn in 180 mm (7 in). Because firing heats up the bore, the air-cooled barrel is equipped with a mechanism to remove and replace the barrel assembly with a spare. A folding bipod with adjustable legs is attached near the front of the weapon, though there are provisions for hard-mounting to a M192 Lightweight Ground Mount tripod or vehicle mount. The M249 provides accuracy approaching that of a rifle, combined with the sustained volume of fire of a machine gun. Its original gas regulator offered two different gas port sizes, allowing cyclic rates of fire of 750 rounds per minute (r/min) or 1,000 r/min. The latter setting was intended for adverse conditions such as an excessively dirty firearm or cold weather. The two-position gas regulator was discarded as part of a product improvement program. Sustained rate of fire, the rate of fire at which the gunner can fire continuously without overheating, is approximately 85 r/min.
he FN Browning .50 caliber machine gun is a variant of the US model, designed to suit European production practices.
The FN Browning M2 HB-QCB is basically a Fabrique Nationale copy of the American design with slight alterations made to suit European production practices. In all actuality, the system - especially the early production models - are fairly close in resembling and operating like their American counterparts.
The FN Browning M2 HB-QCB can be found in varying roles depending on mission-specific usage. These roles include vehicle-mounted firing, tripod-mounted firing or coaxial-mounted firing. A lightweight version is reserved for airborne units and can supply a good 950-1,100 rounds per minute cyclic rate of fire in full automatic. Upgrade kits for older M2 systems were also made available that included new barrels, breech lock system and barrel extension kit. Additional options such as a "anti-cook off" attachment was also supplied to the lightweight airborne model. In all, the FN Browning M2 HB-QCB Series carried on the successful traditions of the lethal American-made Browning Heavy Machine Guns popularized throughout World War Two as a tank, aircraft or pintle-mounted weapon of some noted reliability.
The M3 Tripod adds an additional 43.98 lbs (19.95 kg)of weight to the system when fielded as such.

A U.S. Marine firing the British L7A2 version of the MAG Mechine Gun
The MAG uses ignited powder gases vented through a port in the barrel to propel a gas piston rod connected to the locking assembly (it uses a long-stroke piston system). The barrel breech is locked with a vertically-tilting, downward locking lever mechanism that is connected to the bolt carrier through an articulated joint. The locking shoulder and camming surfaces that guide the locking lever are located at the base of the receiver. The MAG uses a series of proven design concepts from other successful firearms, for example the locking mechanism is modeled on that of the Browning M1918 (BAR) automatic rifle, and the feed and trigger mechanisms are from the WWII-era MG42 universal machine gun.
The MAG fires from an open bolt. Both the spring-powered extractor and ejector are contained in the bolt. After firing, spent cartridge casings are removed through an ejection port located at the base of the receiver (a spring-loaded dust cover of the MG42 type covers the ejection port). The machine gun has a striker firing mechanism (the bolt carrier acts as the striker as it contains a channel that houses the firing pin, which protrudes out from the surface of the bolt upon firing), an automatic-only trigger assembly and a manual cross-bolt push-button safety, which is located above the pistol grip. With the safety placed in the “safe” setting, the sear mechanism is disabled. The safety can only be engaged with the weapon cocked.
South Korean soldier uses Daewoo K3 Mechine Gun
The K3 is a light machine gun resembling the FN Minimi and uses a standard 5.56 mm NATO cartridge. Its greatest advantage is that it is lighter than the M60 and can interchange cartridges with both the K1A and K2. The feed can come from either a 30-round box magazine or a 250-round metal link belt. It can be used with a bipod for the Squad Automatic role, and fitted with a tripod for sustained fire support.
The rear sight is adjustable for elevation and windage, and the foresight can be adjusted for elevation for zeroing. The barrel has a built-in carry handle for ease of changing the barrel. The action is gas piston driven, with a rotating bolt.

French armed forces got their own universal machine gun in 1952 with adoption of the AAT Mle.52 (Arme Automatique Transformable Modele 1952, or transformable automatic weapon model 1952) machine gun in 7.5mm caliber, developed by MAC (Manufacture d’Armes de Chatellerault). It was tested against several other designs, including a MAS M1950 prototype, a gas-operated universal machine gun with combination box magazine / belt feed. AAT M52 is a slim-looking weapon of indigenous design, available in a number of versions (light infantry on bipod and with light barrel, medium infantry on tripod and with heavy barrel, vehicle with heavy barrel). It was not without certain flaws, however, the most important being its retarded blowback action, which is sensitive to headspace adjustments and the timing of the bolt / retarder group. This gun, along with the older M1924/29 light machine gun, served with the French army through the Indo-China and Algeria campaigns, and is still the primary universal machine gun of French armed forces. With the transition to the NATO standards, the M52 machine gun was adapted to the 7.62x51 NATO ammunition, and got re-designated as AAT F1. The AAT M52 / F1 guns are now old, and at the time of writing France had expressed interest in acquiring a replacement GPMG. It seems probable that this will be a foreign design.
The AAT Mle.52 is a retarded blowback operated, air cooled, belt fed, automatic machine gun which fires from an open bolt. Barrels are quick-detachable and available in two versions – “light” (intended for the LMG role) and “heavy” (intended for sustained fire role).
The AAT Mle.52 uses a modified delayed blowback action originally designed by Pal Kiraly before WW2. In this system, the initial opening of the bolt is retarded by a lever which is installed between the light bolt head and the relatively heavy bolt body. When the bolt is in battery, a short arm of the lever rests against a recess in the receiver wall, and the long arm rests against the bolt body. Upon recoil, this lever, which is attached via a pivot to the bolt head, rotates to accelerate the heavy bolt body relative to the bolt head, thus slowing down the initial movement of the bolt head. Once the pressure in the barrel is low enough, the retarding lever exits the recess in receiver, and the bolt group continues its recoil cycle as one unit, extracting and ejecting the spent case on the opening movement and then loading and firing a fresh cartridge if the trigger remains pressed. To assist reliable extraction, the gun has a fluted chamber. While this locking system is relatively simple, it is quite sensitive to headspacing and also permits a lot of fouling, created by burning powder, to get inside the receiver.
The belt feed is more or less a copy of the German MG 42 feed, and is operated by a stud on the top of the bolt body. Feed is from the left side, using disintegrating belts with open pockets. In the 7.62 NATO version, this gun uses American M13 links.
Standard furniture includes a telescoping butt, made of stamped steel, a stamped steel pistol grip with plastic grip panels, a carrying handle and a folding bipod, both attached to the barrel. In the light role the AAT Mle.52 can be fitted with an optional rear monopod; in the sustained fire role, it is installed on a modified US M2 tripod using a special adaptor with traverse and elevation mechanisms. It must be pointed out that while the barrel change procedure for the AAT Mle.52 is quick in theory, in practice it could be less comfortable when the gun is used from a bipod. Since the bipod is attached to the barrel, the gunner has to hold the gun in his hands while his Number 2 replaces the barrel. When the gun is used from more substantial mount, i.e. tripod or vehicle, this is no problem as the mounting via the receiver supports the gun

Squad Automatic Weapon (SAW) CA 249
Completely Upgraded Externally
Weight: 14 lbs
350 fps
Watch This Video
The M249 SAWS is a lightweight, gas-operated, magazine or disintegrating metallic link-belt fed, individually portable machine gun capable of delivering a large volume of effective fire. The M249 AR provides accurate fire approaching that of the rifle yet gives the heavy volume of fire common to a machine gun. The M249 replaces the two automatic M16A1 rifles in the rifle squad on a one-for-one basis in all infantry type units and in other units requiring high firepower. Fielded in the mid-1980s, the SAWS filled the void created by the retirement of the Browning Automatic Rifle (BAR) during the 1950s because interim automatic weapons (M14 Series/M16A1 Rifles) had failed as viable "base of fire" weapons.
