The Mofficially the Machine Gun, Caliber 7.

It is used extensively by infantry m240n, most often in rifle companiesas well as on ground vehicleswatercraft and aircraft. Despite being heavier than some comparable weapons it is highly regarded for reliability and its standardization among NATO members is a major advantage.

All variants are fed from disintegrating belts and are capable of firing most types of 7. M variants can be converted to use non-disintegrating belts. There are significant differences in weight and some features among some versions which restrict interchangeability of parts. The MB and MG are usually fired from an integrated bipoda tripodor a vehicular mount; regarding tripod use, the U.

Marine Corps uses the MA1 tripod, s;ecs slightly updated M2 tripod.

The MAG is a belt-fedgas-operatedair-cooled, crew-servedfixed headspace general-purpose machine gun. Its versatility is demonstrated by its ability to be fired effectively from its integral bipodspeca on a tripodon ground vehicleswatercraft and aircraft.

It was first adopted by the U. Army inas a coaxial tank gun, and slowly adopted for more applications in the s and s. The M and ME1 were adopted for use on vehicles. This led to further adoption in more uses, especially for the Army and Marine Corps infantry.

While possessing many of the same basic characteristics as its predecessor, the durability of the MAG system results in apecs reliability when compared to the M 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. Compared to other machine gunsits rating of 26, mean m240g between failure MRBF is quite high for its weight—in the s when it was first adopted it achieved about 7, MRBF.

It is not as reliable as some very heavy older designs, but it is quite reliable for its mass. They underwent comprehensive testing alongside the older M for comparison. 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.

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. The M was adopted as the U. Army’s standard vehicle machine gun in It then went on to replace many older types of vehicle machine guns in the s.

Navy SEALs continued to use the “CAR” M60E3 version of the M60 machine gun due to its lighter weight and slower rate of fire, which allows a more effective duration of fire with allowable levels of ammunition carried.

The various versions of the M have entirely replaced all the M60 versions, though they have for most main applications and roles. The M60 is still, in some cases, used by the 2m40b. Loading the M can be done either with the bolt forward or to the rear. If the xpecs is to s;ecs forward, the operator will then load the rounds into the feeding block feed tray cover closed ; or will open the feed tray cover, load the rounds onto the feeding tray, then close the feed tray cover.

The charging handle will then be pulled to the rear, which locks the bolt to the rear.

The weapon is then placed on safe and the charging handle is then placed back to the forward position this is spring-loaded on the tank-mounted variation. The weapon is now ready for operation. The weapon fires from the open bolt position, meaning that the bolt is held to the rear and only moves forward as it is firing a round. The firing pin is static and the bolt moves around the firing pin, circumventing any need for a hammer.


A sear is used to spesc the internal mechanisms of the weapon to provide a consistent rate of fire, ensuring proper function and accuracy. However, firing from an open bolt also provides the possibility of an accidental discharge due to a bolt override.

This happens when there is enough force for the bolt to jump over the sear and fire without the trigger being pulled.

The safety on the weapon cannot stop this from happening. The safest way to protect against this is to leave the bolt forward on the weapon until the operator is ready to fire the weapon; then charge the weapon and fire.

Clearing the weapon is performed by ensuring that the bolt is locked to the rear and the weapon is on safe. The top cover is then lifted, the remaining belt if any is swept out of the feed tray, the feed tray is lifted to visually inspect the chamber and the face of the bolt. Any links or brass casings are removed. The weapon is now clear. In the extremely unlikely event that a live round spces on the bolt face, it is knocked loose with a cleaning rod or another rigid xpecs.

If there is a live round lodged in the barrel, the operator must immediately decide if the barrel is hot enough that there is a chance of it cooking off.

He should then wait for the barrel to cool off before attempting to remove it. He can also attempt to extract the round by closing the cover, taking the weapon off of safe, and pulling the trigger. This will likely causing the weapon to fire, so care should be made in ensuring that the weapon is first pointed in a safe direction.

The rate of fire may be controlled by three different gas regulator settings. The first setting allows the weapon to cycle at — rounds per minute, the second setting being — rounds per minute, and the third setting being — 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. It is generally performed only when necessary to return the gun to operation after fouling has caused sluggish operation and specss is no time to properly clean the weapon.

The barrels can be exchanged rapidly, thanks to a barrel release button located on the left side of the weapon. The weapon is cleared first and then the button is held down, while the barrel’s carrying handle is moved from the right side of the weapon to the center, unlocking it from the receiver. At this point, the button is released and the barrel is then pulled free of the receiver and placed to the side.

The new barrel is inserted into the receiver and then the carrying handle is shifted to the right, locking it into place. Headspace is set by counting the speds as the barrel is locked m2240b and should be between two and seven clicks. During prolonged firing, care must be taken to not allow exposed skin to come in contact with the weapon.

The barrels can become spwcs enough to inflict second-degree burns instantly without becoming visibly different. These hot barrels glow brightly to anyone using any sort of optics sensitive to infrared radiation, such as night vision devices. The manufacturer’s name for the weapon is the MAG For example, a US unit with attached British troops could supply replacement parts for the L7s, and vice versa. The M is designed as coaxial machine gun for tanks and 7.

It can also be fitted with spade grips for flexible use, like the ones from the MD. The MC is the right hand variant on the original coaxial installed alongside the main weapon M, it is identical to the M except for the ammunition cover and feed specw. The MC uses a charging cable instead of a charging handle, has a cut-off pistol grip and has a special paddle assembly that allows the trigger to be actuated by means of a solenoid.

Since the machine gun is not meant to be handled during use, the barrel is fully exposed and must be handled with asbestos mittens during barrel changes. The rate of fire of the M, ME1, and MC can be controlled by three different gas regulator settings. It is also still used by some Army units. It comes configured for ground combat with a buttstock spece bipod, though it can also be mounted on tripod, ground vehicles, aircraft, aboard ships and small boats. It is almost always referred m20b as an “M Bravo ” or even just “” verbally.


The M60E4 Mk 43 as designated by the U. Navy was pitted against the ME4 former designation of the MB in Army trials during the s for a new infantry medium machine gun, in a competition to replace the decades-old M60s.

The ME4 won, spec was then classified as the MB.

M mm Machine Gun – Specifications

This led to 1, existing Ms being sent to FN for an overhaul and a special kit that modified them for use on ground such as a stock, a rail, etc. This led to procurement contracts in the late s for the all-new MB. However, a new feature was added, a hydraulic buffer system to reduce the felt recoil as incorporated in the M The MG has three gas settings, allowing the machine gun to have a fire rate between — rounds per minute depending on the setting selected, whereas the MB only has one setting, restricting the fire rate between — rounds per minute.

The smaller gas port used on the MB slows down the rate of fire, which increases the longevity of the machine-gun by reducing stresses on the action. A side effect is a weapon that will not fire when extremely dirty as the energy on the piston is reduced. The Marine Corps relies on fire discipline among its machine gunners to not set it to the largest port unless required. The MB is being tested with a new adjustable buttstock that may replace the current stock of the MB.

The Corps is instead looking to upgrade the M barrel through several ways, including carbon fiber coatings, new alloys, or ceramic liners, to lighten and strengthen the barrel. The goal would be a barrel that would not need to be changed, would weigh the same, but decrease heat retention, lessen warping, and eliminate cook-offs.

They are also interested in incorporating a suppressor into the barrel, rather than having to attach one, to reduce the sound of shots and make it difficult to determine where the gunner is located.

The MD is an upgrade of the ME1, primarily in the addition of an optical rail on the receiver cover.

M240 Machine Gun

It has two possible configurations: In the aircraft configuration, the MD 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 Egress Package contains a buttstock assembly, a buffer assembly, a bipod assembly, and a conventional trigger assembly. The MD is issued for aircraft configuration. The barrel assembly contains a three position gas plug. The first gas plug position allows the weapon to cycle at — rounds per minute RPMthe second gas plug positions allows the weapon to fire at — rounds per minute RPMand the third gas plug position allows the weapon to fire at — rounds per minute RPM.

The aircraft configured MD weighs The MH formerly designated as the ME5 [7] is an improvement of the MD, the MH 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.

The MH has an overall length of The MH entered service in on U.

It is equipped with dual spade grips and thumb-activated trigger systems, and can be quickly converted for j240b infantry use via an egress components kit that includes a bipod and conventional pistol grip trigger module. The MN is designed with a front and rear sights, and configured specifically for mounting on water craft.
