The initial M1918A1 version of the Browning Automatic Rifle (BAR) was first used in combat by American soldiers during World War I, and many saw service in World War II. The BAR received high praise for its reliability under adverse conditions.
In 1940, the model M1918A2 was adopted. Unlike earlier models, it could only be fired in two automatic modes--slow (300 to 450 rpm) or fast (500 to 650 rpm)--but not in semiautomatic mode. Both versions were widely used in the second world war. The USMC preferred the semiautomatic mode in some tactical situations, and modified most of the M1918A2 guns to include that capability. A buffer spring in the butt greatly reduced recoil, to the advantage both of firing accuracy and shooter endurance.
The M1918A2 also mounted its folding bipod (2.38 pounds!) on a special flash hider near the end of the barrel. Since the bipod could easily be detached in this model, it very frequently was! but not often in defensive positions, where it was very effective. The flash hider, which was the point of attachment for the bipod, was not usually removed. Hiding the flash from enemy troops when firing on them isn't the purpose of the hider, all automatic weapons are easily visible when fired at night. It blocks the muzzle flash from the vision of the shooter, maintaining his night vision.
