MAC-58

The MAC-58 was a version of the French AA-52 machine gun using .50 BMG instead of 7.62×51mm NATO cartridges. A few prototypes were tested and one was retained for pre-serial production, but it never reached mass production due to the large quantity of American M2 Browning machine guns already in service with the French armed forces.
