ENGINEERING EVALUATION TEST OF THE M73 MACHINE GUN WITH FIXED EJECTOR.

Abstract

The performance of two M73 machine guns, modified to incorporate a fixed ejector system, was evaluated and the reliability of function of these weapons was compared with that of the standard M73 weapon of current production. The following engineering tests were conducted: preliminary acceptance, heat, cold, simulated tank, sustained firing, elevated firing, depressed firing, ejection, rain, and dust. Based upon the functional results of the limited number of weapons used in these tests, the fixed ejection system is not superior to the standard system. The fixed ejection system, however, has two favorable characteristics: (1) the ultimate reduction of manufacturing cost due to fewer required parts and (2) the inherent advantage of stoppage clearances by immediate-action procedure. Test procedures are described and results discussed. (Author)
