Design and development

Designed primarily as a coaxial machine gun by the Rock Island Arsenal and produced by General Electric, the M73 was developed as a replacement for the M1919A4E1, M1919A5, and M37 machine guns that continued to serve in the immediate post-World War II environment.

The Machine Gun, 7.62-MM, M73 was officially adopted in 1959. It is an air-cooled, recoil-operated machine gun, but also using cartridge gases to boost recoil. Though designed as a simplified alternative to the M1919 series, it is of almost identical weight. The weapon is fitted with a quick-change barrel, pull-chain charging assembly, and can be made to feed from the left or the right hand side (though the left-hand feed is more common).[1]

An attempt to make the M73 useful as a flexible infantry gun saw the weapon fitted with sights and a pistol grip trigger as the Machine Gun, 7.62-MM, M73C. Equally unpopular, very few of these weapons were produced. Sources claim that it saw limited use in Vietnam.[2]

The M73 suffered from numerous malfunctions and was prone to jamming. An improved M73E1 was eventually developed in 1970 with a simplified ejection system, being type classified as the Machine Gun, 7.62-MM, M73A1. In 1972, it was decided that this weapon was sufficiently different from its predecessor and was redesignated Machine Gun, 7.62-MM, M219. These weapons were eventually replaced by the M60E2 and M240 machine gun, and vehicles still in service using the M73 series were refitted with these weapons.[1][2]
