Carcano is the frequently used name for a series of Italian bolt-action military rifles and carbines. Introduced in 1891, this rifle was chambered for the rimless 6.5×52mm Mannlicher cartridge (Cartuccia Modello 1895). It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890 and 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.
