The BAR (short for Browning Automatic Rifle) is a family of American
rifles (or machine rifles) and light
machine guns used by the United States and numerous other countries during
the 20th century. The primary variant of the BAR series is the M1918,
chambered for the .30-06
Springfield (7.62x63mm) rifle
and designed by John
Browning in 1917 for the U.S. Expeditionary Corps in Europe
as a replacement for (and improvement on) the French-made
M1909 machine guns.
Development prototypes of the BAR were presented to a United
States Army Ordnance Board in February 1917, testing was then conducted at Springfield
Armory in May 1917 and on 16 July 1917 12,000 weapons were duly ordered from
Patent Firearms Manufacturing Company known at that time as the BMR
(Browning Machine Rifle).
