FM 24/29 light machine gun

The Fusil-mitrailleur Modèle 1924 Modifié 29 (or MAC 24/29), designed in 1924 by the Manufacture d'armes de Châtellerault, is a 7.5×54mm French light machine gun, which was the standard-issue machine gun of the French Army from 1925 until the 1960s and was in use until 2000–2006 with the National Gendarmerie. == History == The Chauchat machine gun, hastily developed under the pressure of the events of the First World War, gave way around 1925 to the new FM MAC 1924 which fired the brand new 7.5×57mm MAS (7.5×57mm) cartridge.
