This weapon was fully put into service in the [[Second World War]]. This gun was so deadly because it had two modes: selective single shot and fully automatic fire. The BAR was no longer used by American forces after the 1950s, but used by some other armies until the 1970s. | This weapon was fully put into service in the [[Second World War]].
