The MAS 1955 (French: Fusil Automatique Manufacture d'Armes de Saint-Étienne 1955), commonly known as the MAS 55, was a prototype French battle rifle designed in 1955 and produced in very small numbers in prototype form only by the Manufacture d'armes de Saint-Étienne. One of a number of automatic weapon prototypes designed by MAS during the 1950s and 1960s, the MAS 55 was an unsuccessful attempt at replacing the MAS 49 in service.

HistoryEdit

The MAS 55 was one of a number of automatic weapon prototypes designed by engineers at MAS to replace the MAS 49 rifle in service; it was felt that there was a need for the French to standardize their weapons with the then-newly introduced 7.62×51mm NATO cartridge, and to reduce or avoid reliance on other countries for equipment the weapon had to be of French manufacture.[1]

The MAS 55 was made in two variants; a conventional and a bullpup layout. The weapon was never actually submitted to military trials. While the rifle's attempt at replacing the MAS 49 was without success, the work done on the MAS 55 eventually culminated in the design of the FA-MAS Type 62.[2]

Design DetailsEdit

The MAS 55's design was heavily based on the MAS 49, being gas-operated with a tilting bolt. The MAS 55's charging handle was on the left of the receiver and used a number of components from the MAS 49-56.[1]

VariantsEdit

Conventional and bullpup versions were made.
