Since the mid 1990s, the MAG 58 has been employed by the US Army as the M240 which serves as a larger alternative to the M249 SAW to be used primarily as a coaxial weapon for vehicle applications (first or secondary armament for humvees, tanks, helicopters, etc).
 Hearing the sound of an M2 could often cause enemy infantry to take cover.
During World War II, a faster-firing Browning was developed for aircraft use. The M2 can be battle-ready and easily interchanged if it is preemptively fitted with a retracting slide assembly on both sides of the weapon system. The Finnish variant was designated VKT 12,70 LKk/42 and was produced by the state of Finland.
Fixed-mounted forward-firing primary aircraft armament (AN/M2 and AN/M3 light-barrel versions only). For bombers the AN/M2 was used in both flexible and fixed positions for both offensive and defensive use.

There was no fixed water-cooled version.  The weapon was particularly hated by the Germans, whose attacks and ambushes against otherwise helpless stalled motor convoys were frequently broken up by .50 caliber machine gun fire. 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. By the late 20th century, the M2 was the only adjustable headspace weapon in the U.S. inventory. The fixed types fire from a solenoid trigger and come in left or right hand feed variants for use on the Mk 56 Mod 0 dual mount and other mounts. Their aim was to make a light, reliable heavy machine gun with the same damage output as a 20 mm autocannon.
Firing and charging are achieved by pull on one of two color-coded pull chains (black for charging and red for firing), or firing could be initiated by means of a switch activated solenoid on the M-19 cupola elevation mechanism. The legs have spades to dig into dirt or sand to be a stable platform. Read Next: Are Special Operations units going to adapt this SHOT Show machine gun? The M296 differs from previous remote firing variants in that it has adjustable firing rate (500–850 rpm), while lacking a bolt latch (allowing single-shot operation). The German rounds had a muzzle velocity of 2,700 ft/s (820 m/s), an 800 gr (52 g) bullet, and could penetrate armor 1 in (25 mm) thick at a range of 250 yd (230 m). Yet, some seem perennial.
, There are several different types of ammunition used in the M2HB and AN aircraft guns. In the dual-purpose vehicle mount, the M2HB (heavy barrel) proved extremely effective in U.S. service: the Browning's .50 caliber AP and API rounds could easily penetrate the engine block or fuel tanks of a German Bf 109 fighter attacking at low altitude, or perforate the hull plates and fuel tanks of a German half-track or light armored car. The AN/M2 designation was also used for other aircraft guns and therefore it is important to write the caliber before the designation. All .50 ammunition designated "armor-piercing" was required to completely perforate 0.875 inches (22.2 mm) of hardened steel armor plate at a distance of 100 yards (91 m) and 0.75 inches (19 mm) at 547 yards (500 m). See a page that needs some love? The other dimension that could not be held close enough was when the firing pin would fall.  Note the Swedish Air Force used a different designation system which recognized the incendiary rounds as grenades, thus it was called autocannon. Fixed headspace and timing reduces risk, and the carrying handle allows the barrel to be switched in seconds.
 Vehicles would frequently "recon by fire" with the M2 Browning, i.e. All Rights Reserved. , When the M2 was first being designed, John Browning faced two design challenges. , Towards the end of the war, as Luftwaffe attacks became less frequent, the quad .50 (nicknamed the Meat Chopper or Krautmower) 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.  While the dual-purpose mounting was undeniably useful, it did normally require the operator to stand when using the M2 in a ground role, exposing him to return fire.

.50, M2, HB, Flexible. Calibre 13,2 mm, more commonly known as the FN Browning M.1939. To achieve this they raised the firing rate to 1080 rpm and gave it a more powerful cartridge in form of the 13.2x99 mm Hotchkiss. This article incorporates public domain material from the United States Army website https://peosoldier.army.mil/newpeo/Folio2010/PMSW/PM_CSW/XM205.xml.  The "AN" stands for "Army/Navy", since the gun was developed jointly for use by both services. The Browning M2 .50 caliber (12.7mm) Machine Gun, is a World War II era automatic, belt-fed, recoil operated, air-cooled, crew-operated machine gun.
Since Finland was already producing 12.7 mm ammunition, the Finnish variant was rechambered to 12.7 mm (.50 bmg).
The M2 machine gun has also been used as a long-range sniper rifle when equipped with a telescopic sight. Development with the French round was dropped.
He has extensive experience in maritime special operations and combat medicine.
The M240 is also easy to jam feed, which allows you to keep your barrel on target and get back in the fight quicker.  Many commanders thought that the .50 Browning the best weapon in its class, certainly the best of the American weapons, including the M1 Garand and M1 Carbine. The Gau-17 Minigun is about as badass as it gets, but it has its limitations.
In its ground-portable, crew-served role as the M2HB, the gun itself weighs 84 pounds (38 kg) and the assembled M3 tripod another 44 pounds (20 kg). 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.
