After World War I, Army Ordnance studied all the equipment used in that world-wide conflict. It was decided that a new US rifle was needed that would be able to more quickly respond to “over the top” charges by enemy troops and also for trench close-in engagements.
Some semi-automatic rifle designs were starting to show up early on and did show promise to meet some of the standards they wished to address.
Also during this time the Browning Automatic Rifle (BAR) was reviewed because of its automatic capabilities, BUT complaints were put forth that the magazines were cumbersome, being dropped, getting dirty and even being lost—the Brit’s also reported similar problems with their Lee-Enfields. Not much firepower loading one round at a time!
Therefore, Army Ordnance did require that the new battle rifle must have an internal magazine—the “PING” has been with us for World War II, Korea and even later conflicts.
