[11] It was type classified in the fourth quarter of fiscal year 2010.[15][16]. The M240, officially the Machine Gun, 7.62 mm, M240 or unofficially the M240 Bravo, is the U.S. military designation for the FN MAG (Mitrailleuse A Gaz, "gas-operated machine gun"; alternatively, Mitrailleuse d'Appui General, "general support machine gun"), a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge. [75], Due to the aforementioned improvements the gun received interest from numerous nations when it entered the export market in 1939. Clearing the weapon is performed by ensuring that the bolt is locked to the rear and the weapon is on safe. [10] The lighter M240L has started to replace the M240B in US Army service. The M2HB was used in Korea and Vietnam, and later in both Operation Desert Storm, the Afghan theater of Operation Enduring Freedom and in Iraq. The third setting allows the weapon to have a cyclic rate of fire around 850–1235 rounds per minute.

Primary or secondary weapon on a naval patrol boat. The M240H (formerly designated as the M240E5)[7] is an improvement of the M240D, the M240H features a rail-equipped feed cover, an improved flash suppressor, and has been configured so that it can be more quickly converted to infantry standard using an Egress Kit. In fixed offensive configurations, like on the B-25 Mitchell, commonly carried 6 to 12 fixed guns for strafing. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan in the 2000s and 2010s. The armor made aircraft machine guns using conventional rifle ammunition (such as the .30-06) ineffective. Winchester worked on the cartridge, which was a scaled-up version of the .30-06. The results for the evaluated machine guns were the following: The MAG itself underwent some improvements and the M60E2 was a specialized coaxial variant that differed from some of the other types. [63] It was made with a picatinny rail on the receiver in order to have quick installation of various optics. The Mk 48 is a variant of the M249 LMG, scaled up to chamber 7.62×51mm NATO; it has come across some issues in its service life; it was never designed to be a general-purpose machine gun, while the M60E6 arguably came too late to make a difference in USMC and US Army general machine gun adoption, being that the M240 design was well standardized within the DoD ranks. The adapter is very distinctive, attaching to the muzzle with three rods extending back to the base. However, Burp Gun was also the slang term that has entered the dictionary to describe any small machine pistol or sub gun. The M240E1 is the U.S. Marine Corps version of the original M240 coaxial/pintle-mounted machine gun that is used on vehicles like the LAV-25. The USMC adopted the M240G for this role in 1991, where it not only replaced the original M60s used by the Marine Corps infantry, but also the upgraded M60E3 that the Marines had started using in the 1980s. [12], Consequently, the American Expeditionary Force's commander General John J. Pershing asked for a larger caliber machine gun. Full/semi auto; Customize it with your own AR Stock and or Pistol grip ... Crosman acts like they cant get a hold of one. [69] As of November 30, 2012, 8,300 built or converted M2A1s had been fielded by the U.S. Army; the program will upgrade the Army's entire M2 inventory of more than 54,000 guns. The first setting allows the weapon to cycle at 650–750 rounds per minute, the second gas setting allows the weapon to cycle at 750–850 rounds per minute, and the third setting allows the weapon to cycle at 850–950 rounds per minute. The Marine Corps also adopted the M240 and M240E1 for use on vehicles like the LAV-25. The AN/M2 designation was also used for other aircraft guns and therefore it is important to write the caliber before the designation. [14] The French 11 mm round was found to be unsuitable because its velocity was too low. Browning scaled up the .30-06 round to .50 caliber (12.7-millimeter) initially for use as an anti-tank round and then adopted it for the resulting new machine gun, the water-cooled M1921. Instead of the operator using a cheek weld on the stock, the operator can now rest his face against the actual receiver of the machine gun, it also allows the operator to have a closer fit of the weapon. This is achieved by using a 0.30-inch-diameter (7.6 mm) tungsten penetrator. [26] The upgraded M2A1 has a manual trigger block safety. Besides vehicle-mounted weapons, the heavy weapons companies in a World War II U.S. Army infantry battalion or regiment were each issued one M2 Browning with tripod (ground) mount. (U.S. Army) It also maintains more speed during flight. [28] The API and APIT rounds left a flash, report, and smoke on contact, useful in detecting strikes on enemy targets; they were primarily intended to incapacitate thin-skinned and lightly armored vehicles and aircraft, while igniting their fuel tanks. Corps Not Looking at M240L — But a Silenced M240B? This is the exact antithesis of a muzzle brake. The bolt group is still the same as the original M240 design, with the exception of the position of the sear catch. The solution to these problems was adjustable timing and headspace ("headspace" is the distance between the face of the bolt and the base of the cartridge case, fully seated in the chamber); the operator had to screw the barrel into the barrel extension, moving the barrel toward the bolt face to reach the proper headspace with simple gauges to allow the operator to adjust to the proper dimensions. The M240G lacks a front heat guard, and as such is a few pounds lighter than the M240B, weighing in at 25.6 pounds (11.6 kg). On gas setting one the weapon will fire at 650–750 rounds per minute, on gas setting two the weapon will fire at 750–850 rounds per minute, and on gas setting three the weapon will fire at 850–950 rounds per minute. [48] However, it was used by fast-moving motorized forces in the Philippines to destroy Japanese blocking units on the advance to Manila. However, funding was lost before the design could be fully evaluated and the program ended. [53][54] In North Africa, after Commonwealth units began to obtain sufficient parts, manuals, gauges, and ammunition for the new weapon, the .50 Browning was increasingly used, eventually replacing the 15 mm Besa,[53] but in Italy it was often deleted from top turret mountings because the mount exposed the operator to low branches and enemy fire. A Jordanian soldier fires the M2 .50-cal. The GAU-16/A was an improved GAU-15/A with modified grip and sight assemblies for similar applications. [45][46][47], The M2HB was not widely used in the Pacific campaign for several reasons, including the weight of the gun, the nature of infantry jungle combat, and because road intersections were usually easily outflanked. The M240 and M240E1 were adopted for use on vehicles. It is the primary heavy machine gun of NATO countries, and has been used by many other countries as well. [51], Towards the end of the war, as Luftwaffe attacks became less frequent, the quad .50 (nicknamed the Meat Chopper or Krautmower[51]) was increasingly used in an anti-personnel role, similarly to the earlier-introduced (1940) and more powerful—but much more difficult to keep well-fed with ammunition when in action—German 20 mm Flakvierling. It then went on to replace many older types of vehicle machine guns in the 1980s. Caliber:.25 ACP (6.35 Browning) Capacity: 7+1 In the aircraft configuration, the M240D has a front and rear sight and a trigger group which accommodates the spade grip device, while the ground configuration involves the installation of an egress package or "infantry modification kit", which is designed to provide downed aircrew personnel with increased firepower. The design has had many specific designations; the official US military designation for the current infantry type is Browning Machine Gun, Cal. The misconception may have arisen during the Korean or Vietnam Wars when U.S. troops were told to use their M2s only against enemy equipment due to shortages of ammunition. [2] This has significant advantages in training, logistics support, tactical versatility, and joint operations. Ordnance[11] for use by the U.S. government, and for allies via Foreign Military Sales, as well as by foreign manufacturers such as FN Herstal. A feed chute adapter is attached to the left- or right-hand feed pawl bracket allowing the weapon to receive ammunition through a feed chute system connected to externally mounted ammunition containers holding 600 rounds each. In 2007, the military found money to start a new competition. Two main criteria analyzed were "mean rounds between stoppages" (MRBS, malfunctions that can be cleared within minutes) and "mean rounds between failures" (MRBF, such as a part breaking). This allows the operator to feed a belt of ammunition into his 240LWS without ever having to possibly expose his position or line of sight, by opening the feed tray cover. Although we … The M240P is not used as often as its predecessors. Most US fighter aircraft were armed with four, six or eight AN/M2 MGs mounted in the wings. [68] The M2A1 was named one of the greatest Army inventions of 2011. By the late 20th century, the M2 was the only adjustable headspace weapon in the U.S. inventory. .50, AN/M2" (Fixed) or (Flexible). The fixed, remote-firing version, the FN M3P, is employed on the Avenger Air Defense System, and is currently used on the OH-58D, augmenting the XM296 .50 cal. A heavy barrel M1921 was considered for ground vehicles. As of July 2017, it is not yet clear if that adapter is compatible with the M192 or M122 Traverse and Elevation (T&E) mechanism. The M240G can be modified for ground use by the installation of an "infantry modification kit" (a flash suppressor, front sight, carrying handle for the barrel, a buttstock, infantry length pistol grip, bipod, and rear sight assembly). The rate of fire may be controlled by three different gas regulator settings. The MAG actually has a more complex gas system than the M60, but gives better reliability combined with lower maintenance requirements, though this comes at greater manufacturing cost and weight. The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun designed toward the end of World War I by John Browning. The basic infantry model, Browning Machine Gun, Cal. machine gun. The M2 has been in use longer than any other firearm in U.S. inventory except the .45 ACP M1911 pistol, also designed by John Browning. Snipers firing from trees were engaged by the quad gunner at trunk level; the weapon would cut down and destroy the entire tree, and the sniper with it.[43][49]. 無料 … The Army M240 converted to the M240B configuration should not be confused with the large numbers of M240/E1 converted to the M240G configuration for the Marine Corps. The Browning M2 is an air-cooled, belt-fed machine gun. Browning Machine Gun .50 Caliber HB, M2 - 1:1 Scale Replica Plans and free FM23-65 Field Manual. In the late 1990s, the Army adopted the M240B for the infantry role – they had considered the M60E4, which (though lighter and cheaper) did not offer commonality with the vehicle-borne M240, other FN MAG users within NATO, or the USMC. Crosman R1 Full-Auto CO2 BB Gun. Though it is heavier than some comparable weapons, it is highly regarded for reliability and its standardization among NATO members is a major advantage. The first setting allows the weapon to cycle at 650–750 rounds per minute, the second setting being 750–850 rounds per minute, and the third setting being 850–950 rounds per minute. These settings are changed by dismounting the barrel, removing the gas regulator collar and turning the gas regulator to allow more or less gas to move through the weapon system. [76] The "AN" stands for "Army/Navy", since the gun was developed jointly for use by both services. It has two possible configurations: aircraft and egress (ground). There was no fixed water-cooled version. The qualities of the M60 variants vary considerably, such as between the M60E4 and the M60C. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. [61] It is also possible that a restriction during the latter period limiting the use of the M40 recoilless rifle's .50-caliber spotting gun to destroying enemy equipment only, since the M40 was meant to be used against armor and firing the spotting gun at personnel would have given away the M40's position before it could be used as intended, was mistakenly believed to apply to all weapons of that caliber and given legal justification.[60]. A number of designs of the period from various countries were considered; the final two candidates were the M60E2 and the FN MAG.

Auction will be held on Tue Jan 19 @ Time TBA at 310 N. Dysart Road in Avondale, AZ 85323. The subvariant designation Browning Machine Gun, Cal. [citation needed]. The second setting allows the weapon to have a cyclic rate of fire around 750–850 rounds per minute. Their aim was to make a light, reliable heavy machine gun with the same damage output as a 20 mm autocannon. In Sweden it was re-designated 12,7 mm automatkanon m/45 (short 12.7mm akan m/45) meaning 12.7 mm autocannon m/45. This was formally known as the M240B Weight Reduction Program, or the M240E6.

During World War I, the Germans introduced a heavily armored airplane, the Junkers J.I. .50, M2, with others as described below. The M240 was adopted as the U.S. Army's standard vehicle machine gun in 1977. When a standard M2 had a barrel change, the headspace and timing had to be manually set. The 12.7 mm AN/M2 had a cyclic rate of 600–800 rounds per minute, with the ability to be fired from an electrically operated remote-mount solenoid trigger when installed as a fixed gun. [65], On October 15, 2010, the M2A1 heavy machine gun was type classified by the U.S. Army. In 2020, Geissele Automatics acquired the 240LWS's design. Model Jet Engine Plans . Soldiers during the Korean War used scoped M2s in the role of a sniper rifle, but the practice was most notably used by US Marine Corps sniper Carlos Hathcock during the Vietnam War. Secondary weapon for anti-boat defense on large naval vessels (corvettes, frigates, destroyers, cruisers, etc.). The M60 is still, in some cases, used by the Navy. Kriss plans to demonstrate the new Vector at the 2020 SHOT Show later this month. The GAU-21/A is also being used by the U.S. Marine Corps to upgrade from the XM-218/GAU-16 .50 cal. It is used extensively by infantry, most often in rifle companies, as well as on ground vehicles, watercraft and aircraft. Because the M2 was designed to operate in many configurations, it can be adapted to feed from the left or right side of the weapon by exchanging the belt-holding pawls, and the front and rear cartridge stops (three-piece set to include link stripper), then reversing the bolt switch. After World War II, the .50 Browning continued to see action in Korea and other theaters, in aircraft, tripod (ground), ground AA (hip-ring), and vehicle mounts. Green studied the design problems of the M1921 and the needs of the armed services. [66][67] In June 2011, the Army began conversion of M2HB machine guns to M2A1s. In Sweden the weapon received the designation Automatkanon m/39, short Akan m/39, meaning Autocannon m/39 and was later produced by Ericsson as the Akan m/39A. It has a right-handed feed for use on the M2/M3 Bradley Fighting Vehicle and LAV as the coaxial machine gun. Any links or brass casings are removed. In the extremely unlikely event that a live round is on the bolt face, it is knocked loose with a cleaning rod or another rigid object. While Improbable Aiming Skills are all very well and good, sometimes you just need to throw a wall of bullets at the target — perhaps your foe can Dodge the Bullet, or you're up against a whole army of Mooks at once. Should relations between the United States and these countries sour, it would become much harder to find sources of titanium. [27], There are several different types of ammunition used in the M2HB and AN aircraft guns. Due to the start of World War 2 and the invasion of Belgium it was exported to only Romania and Sweden. The egress package contains a buttstock assembly, a buffer assembly, a bipod assembly, and a conventional trigger assembly. The program called for a much lighter version of the M240, while keeping the same familiar open bolt design that the machine gun is world-renowned for. There are two telescoping rods that allows the buttstock to be extended to the desired position, when depressed from the top portion. The design concept of this variant is to produce a viable medium machine gun that would serve in a special operations capacity, where a small team of operators could maximize a medium machine gun by having it in a shorter and lighter package than its big brother, the 240LW, or the equivalent M240B. The latter ammunition along with the M903 SLAP (Saboted Light Armor Penetrator) round can perforate 1.34 inches (34 mm) of FHA (face-hardened steel plate) at 500 metres (550 yd), 0.91 inches (23 mm) at 1,200 metres (1,300 yd), and 0.75 inches (19 mm) at 1,500 metres (1,600 yd). For fixed (offensive) or flexible (defensive) guns used in aircraft, a dedicated M2 version was developed called the ".50 Browning AN/M2" or the "12.7 mm AN/M2". .50, M2, HB, TT was only used for manufacturing, supply, and administration identification and separation from flexible M2s. Barrett had to move the position of the sear catch on the bolt to further down the length of it. During prolonged firing, care must be taken to not allow exposed skin to come in contact with the weapon. The M2HB has been in service with the Israel Defense Forces since its establishment and has served in all of Israel's wars, operations, and conflicts. It is equipped with dual spade grips and thumb-activated trigger systems, and can be quickly converted for dismounted infantry use via an egress components kit that includes a bipod and conventional pistol grip trigger module. Unlike virtually all other modern machine guns, it has no safety (although a sliding safety switch has recently been fielded to USMC armorers for installation on their weapons and is standard-issue for the U.S. Army for all M2s). The M240 has been used by the United States Armed Forces since the late 1970s.

The M240H entered service in 2004 on U.S. Army helicopters. By moving the fire control group forward, the overall length can be shortened because the machine gunner no longer needs a traditionally longer stock to compensate for the original position of the pistol group, towards the very rear portion of the receiver. Today, it can be found on the Embraer EMB 314 Super Tucano as designated as M3W with minor modification, which are installed in the wings (2 ea of M3Ws) with 250 rounds each. In 2003, U.S. Army SFC Paul Ray Smith used his M2HB mounted on an M113 armored personnel carrier to kill 20 to 50 enemies who were attacking a U.S. outpost, preventing an aid station from being overrun and allowing wounded soldiers to be evacuated,[50] SFC Smith was killed during the firefight and was posthumously awarded the Medal of Honor. However, a new feature was added, a hydraulic buffer system to reduce the felt recoil as incorporated in the M60. The M240H has an overall length of 41.6 in (1056.6 mm) with a 21.7 in (551.2 mm) barrel and weighs 26.3 pounds (11.9 kg) empty, and has a cyclic rate of fire of around 550–650 rounds per minute. [13], The M240N is designed with a front and rear sights, and configured specifically for mounting on water craft. Manufactured by Fabrique Nationale d'Herstal, the FN MAG was chosen by the U.S. military for different roles after large worldwide searches and competitions. Three subvariants were also developed for use by the U.S. Navy on a variety of ships and watercraft including the soft mount and fixed type versions. The Army Ordnance Department ordered eight experimental Colt machine guns rechambered for the French 11 mm cartridge. The M2 Heavy Barrel, M48 Turret Type was developed for the commander's cupola on the M48 Patton tank. Feed system: NATO standard disintegrating link belt-fed, Length: 1,230 mm (48.5 in) with the standard barrel and 1,130 mm (44.5 in) with the short barrel, Maximum effective range: 1,100 meters with tripod and T&E (the latest FM reads 1,800 m), Cyclic rate of fire (hydraulic buffer): 550–650 rounds per minute, Weight: 9.1 kg (20.15 lb), while unloaded, Maximum effective range and T&E: 1,100 meters with tripod, Cyclic rate of fire: 550–600 rounds per minute, Length: 1079.5 mm (42.5 in) with the standard barrel and 977.9 mm (38.5 in) with the short barrel, Barrel length: 582.6 mm (22.9 in) standard barrel and 480.3 mm (18.9 in) short barrel, Weight: 9.30 kg (20.5 lb) with the standard barrel and 8.96 kg (19.75 lb) with the short barrel, while unloaded, This page was last edited on 6 February 2021, at 05:36. The other dimension that could not be held close enough was when the firing pin would fall. The barrels can become hot enough to inflict second-degree burns instantly without becoming visibly different. The rate of fire of the M240G can be controlled by three gas settings. They had light-weight barrels and the ammunition fed only from the left side. The handguard also has Keymod rail sections at the 3, 6, and 9 o'clock positions, with the side sections being separated from the bottom by a gripping surface for the operator.[20]. When firing semi-automatically, Hathcock hit man-size targets beyond 1,800 metres (2,000 yd)—twice the range of the standard-caliber sniper rifle of the time (a .30-06 Winchester Model 70). Unlike the current M240's solution of minimizing the heat transfer, Barrett uses a free floating handguard system, where they bolted the handguard directly to the receiver of the machine gun, instead of to the gas tube assembly. The US Navy and Coast Guard likewise utilize the weapon system, and is also still used by some units in the US Army. The bullet was of a high explosive type and was designed to take down a small aircraft with a single hit. The MAG is a belt-fed, gas-operated, air-cooled, crew-served, fixed headspace general-purpose machine gun. The Lima is in limited service with the U.S. The various versions of the M240 have not entirely replaced all the M60 versions, though they have for most main applications and roles. [42] The quad mount .50 was also used to destroy Japanese emplacements.[49]. Saco Defense had since been acquired by General Dynamics, which won the competition. Winchester initially added a rim to the cartridge because the company wanted to use the cartridge in an anti-tank rifle, but Pershing insisted the cartridge be rimless. The short barrel is 4 in (100 mm) shorter than a standard M240 barrel, and with the collapsible stock the M240L can be made 7 in (180 mm) shorter. The original water-cooled version of the M2 was used on a tall AA tripod or vehicle-mounted anti-aircraft weapon on a sturdy pedestal mount. [20], The Barrett 240LW is a general-purpose machine gun capable of mounting on a bipod, tripod, aircraft, or vehicle. A sear is used to time the internal mechanisms of the weapon to provide a consistent rate of fire, ensuring proper function and accuracy. The results of that solicitation ended with the adoption of the M240L by the U.S. Army. Its versatility is demonstrated by its ability to be fired effectively from its integral bipod, mounted on a tripod, on ground vehicles, watercraft and aircraft. Both offerings are more focused on Special Operations in US Service. The design of the feed tray cover hinge has been altered to be in the shape of a hexagon, thus allowing for the feed tray cover to be able to stay open while at a 45 degree angle to the receiver, while the machine gunner is loading a belt of ammunition. The size of the gas port increases resulting in greater energy being delivered to the action. [20], The position of the pistol grip and firing control group has been redesigned to make the 240LWS even shorter than the 240LW. EVOlution Graphics B.V. Hilversum, The Netherlands KvK 60955899 VAT Nr. Titanium was used to make the receiver body, front sight post, and carrying handle while maintaining steel operating system components.
