The Browning Automatic Rifle (BAR) was a .30 inch calibre gas operated automatic rifle, or light machine-gun, designed by John Browning in 1917 for the purpose of providing covering fire to troops crossing no-mans-land against machine gun fire, and manufactured by Winchester, Colt and other companies from 1918 onwards. The BAR took a 20-round box magazine and had a cyclic rate of 350 or 600 rounds per minute, a muzzle velocity of 855 meters per second and an effective range of 600 meters. It had either a 610 mm long barrel or in the M1922 model a 457 mm long barrel and was fitted with a blade foresight and a tangent leaf with aperture rearsight and a bipod.
