卡尔卡诺是过去意大利常用的手动枪机操作式一系列军用步枪和卡宾枪，最初于1891年推出时，发射的是6.5×52毫米曼利彻-卡尔卡诺口径无缘式步枪子弹（Cartuccia Modello 1895）。这枝步枪是由首席技师萨尔瓦多·卡尔卡诺在都灵军兵工厂于1890年研发，并且称为M91。它先后取代了以往的10.35×47毫米RVetterli-维塔利步枪和卡宾枪以，在1892年到1945年之间生产。在第一次世界大战期间的大多数意大利部队和第二次世界大战中的意大利以及德**队之中一些部队里，采用了M91的步枪（fucile, sing.；fucili, pl.）和卡宾枪（moschetto, sing.；moschetti, pl.）各两种的型号。在过程中，步枪也被芬兰于冬季战争中使用，以后又在叙利亚、利比亚、突尼斯和阿尔及利亚这些国家战后的各种冲突中被正规和非正规部队使用。

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 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. The M91 was used in both rifle (fucile) and carbine (moschetto) form by most Italian troops during the First World War and by Italian and some German forces during the Second World War. 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.
