The Mas 49/56 rifle is an improved version of the original Mas 49 French rifle. The MAS-49/56 was introduced in 1957 and incorporated lessons learned from service in Algeria, Indochina, and the Suez Crisis. The rifle was shortened and lightened to improve mobility for mechanized and airborne troops. The MAS-49 built-in rifle grenade launcher was replaced by a combination compensator/rifle grenade launcher that fired NATO-standard 22mm rifle grenades. The rifle also incorporates an integral grenade launching sight that is attached to the front sight block and a gas cutoff that prevents gas from entering the gas tube from the gas port when firing grenade launching blank ammunition. Chambered in the 7.5MM French ( 7.5 X 54 ) round. This is a very unique and collectible rifle. These have not been available for years. Don\'t miss this chance to add one to your collection.
