Browning M1918 BAR (Browning Automatic Rifle)

History of the Browning M1918 BAR (Browning Automatic Rifle)

During the First World War (1914-1918), infantry-level automatic weapons were just beginning to realize their potential. Automatic rifles appeared, as well as fully automatic machine guns and semi-automatic pistol types.

To provide more portable firepower to the U.S. infantry, John Browning developed his "Browning Automatic Rifle" ("BAR"), adopted by the U.S. Army as the "Model 1918" or M1918. The classic and extremely reliable design was used in some periods of the two world wars and the Cold War (1947-1991).

The French army of World War I came to appreciate the concept of infantry-level automatic weapons, and when the Americans entered the war in 1917, the French passed that appreciation to their newest allies. "Walking Fire" is the term for the concept of standard infantry-wielding weapons to fire large amounts of ammunition at the enemy. Since trench warfare was infiltrating battlefields throughout Europe at this time, heavy firepower was required to clear obstacles such as stubborn, burrowing enemies.

Browning set out to develop this weapon and decided to use a pneumatic system based on pistons moving inside cylinder assemblies. The assembly is mounted under the barrel, and the open bolt action is contained in a nearly featureless rectangular receiver. The "hump" along the top of the receiver is pushed by the upwardly curved bolt lock.

The extraction port is placed on the right side of the receiver as usual. The magazine feed is located directly in front of the trigger assembly, and the stock of the weapon forms a traditional rifle stock. Wooden furniture for this component, as well as handguards under the front of the weapon.

The overall design of the magazine is straight and slopes along its bottom. Front and rear sights allow for accurate shooting from a distance.

The M1918 had some flaws in its design - it relied on complex internal mechanisms to operate, and its machining process meant it was expensive and time-consuming to manufacture. However, this also resulted in the weapon being rock-solid in the harshest battlefield conditions, nearly indestructible compared to military firearms.

The weapon was designed, developed and tested in a short period of time. Models originally sold had a fire selector that allowed the operator to choose between single (semi-automatic) or fully automatic fire.

Over time, this feature was dropped in favor of a rate-of-fire selector that the operator could set between 350 and 550 rounds per minute.

The

BAR never lived up to Browning's expectations, but at its core was an effective weapon. It eventually became an "intermediate" weapon: due to its limited 20-round magazine (requiring frequent reloads) and lack of control when firing fully automatic, it could not be considered a true LMG and was not considered A true battle rifle as it is inherently heavy like a military rifle and lacks accuracy due to vibration.

During World War II (1939-1945), the BAR became the standard light machine gun (LMG) for the American infantry. Naval units also received this type, but preferred the single-shot capability of the vanilla and therefore reverted to single-shot/full-fire mode. It enjoyed a long and healthy life for Americans, and it didn't officially serve on the front lines until the 1950s.

During World War II, BARs were also issued to members of the British Home Guard. In addition to two world wars, the M1918 was used on the battlefields of the Korean War (1950-1953) and the Vietnam War (1955-1975).

The original model was the M1918, which had a smooth tapered barrel assembly without bipod support. A swivel is placed between the handle and the end of the shaft. The M1922 was the first major attempt to improve the M1918 gun. It comes in a ribbed barrel arrangement. This model has limited circulation and service in the U.S.

Army cavalry. In 1931, Colt marketed a prison guard/law enforcement version as the "Colt Surveillance Automatic Rifle (R80)." This version has no bipod and has a special pistol grip.

The 1937 M1918A1 featured a double stock plate that doubled as a swivel stock. A collapsible bipod ("pointy" feet) has now been added to the cylinder in front of the wooden front end. The 1938 M1918A2 had a shortened front end and an internal metal plate to protect the recoil spring from overheating and warping/breaking. Bipods have been redesigned to have "sliding feet", and monopods are optional.

One of the most important changes to the production line is the removal of single-shot firing in the M1918A2.

The M1918 achieved impressive export figures (over 100,000 were built from 1917 to 1945) and lasted until the 1970s. Operators range from Argentina and Austria to Turkey and Uruguay, with conflicts spanning the Second Sino-Japanese War, the Chinese Civil War, the Palestinian Civil War, the First Indochina War, the Bay of Pigs Invasion, the Cambodian Civil War and the Turkish Invasion of Cyprus.

Export models include the Type 1919 (U-shaped) automatic machine gun, the Type 1924 and its modification, the Type 1925 (R75). Belgium adopted this weapon as the FN Mle 1930 (described in detail elsewhere on this site), and also adopted the FN Mle D version. Polish model is Browning wz. 1928 and Karabin Maszynowy Obserwatora wz. 37.

Swedish brands include Kg m/21, Kg m/37 and Kg m/21-37.
