Carcano is the frequently used name for a series of Italian bolt-action, magazine-fed, repeating military rifles and carbines. Introduced in 1891, this rifle was chambered for the rimless 6.5×52mm Carcano round ("Cartuccia Modello 1895"). It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890, and was originally called the Modello (model) 91 or simply M91. Successively replacing the previous Vetterli-Vitali rifles and carbines in 10.35×47mmR, it was produced from 1892 to 1945. The M91 was used in both rifle ("fucile") and shorter-barreled carbine ("moschetto") form by most Italian troops during World War I and by Italian and some German forces during World War II. The rifle was also used during the Winter War by Finland, and again by regular and irregular forces in Syria, Libya, Tunisia and Algeria during various postwar conflicts in those countries.
