Historical profile
Development
The Browning Automatic Rifle (BAR) M1918 was designed by John Moses Browning in 1917 to provide American troops in France with a portable automatic weapon for 'walking fire' advances.
It entered service in September 1918, too late to significantly impact World War I, but was produced in over 700,000 units across its various versions.
Design
It operates on long-stroke gas piston with a tilting bolt, chambered in .30-06 Springfield, fed by 20-round magazines.
The 1938 M1918A2 variant introduced a folding bipod under the flash hider, a reinforced stock and a two-rate automatic selector (450 and 650 rpm), eliminating semi-automatic fire.
Operational service
It was the standard squad automatic weapon of U.S. forces in World War II and the Korean War, present in every rifle squad.
It also served in Vietnam and was produced under license in Belgium (FN Mle 1930), Sweden (Kg m/21) and Poland (wz. 1928), remaining in service in many armies until the 1970s.
