M2 .50 Dragon 1/6
The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun designed by John Browning towards the end of World War I. Although similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7mm) cartridge. The design has had many names; the official US military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, flexible. It has been used against infantry, light armored vehicles, watercraft, light fortifications and low-flying aircraft.
The gun has been used extensively by the United States since the 1930s as a vehicle weapon and for aircraft armament. It was used extensively 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. It is the main heavy machine gun of NATO countries and is also used by many other countries. US forces have used the M2 longer than any other firearm except the .45 ACP M1911 pistol, which was also designed by John Browning.
The M2HB (heavy barrel) is manufactured in the US by General Dynamics, Ohio Ordnance Works, US Ordnance and FN Herstal for sale to the US government and other countries through Foreign Military Sales.
