How a MAS 49/56 works

The MAS-49 arrived after a series of small, distinct design improvements. Today, this might be termed spiral development, where small elements are changed with successive models, rather than large significant changes. This French semi-automatic rifle evolved from the prototype MAS-38/39 and from the MAS-40, and lastly from the post-war MAS-44 and its minor variants 44A, 44B and 44C. Although 50,000 MAS-44 rifles were ordered in January 1945, only 6,200 were delivered to the Marine Nationale. The MAS-49 was formally adopted by the French Army in July 1949.
