Originally created by Amerigo Cei-Rigotti, an officer in the Italian Army, in 1890, the Cei-Rigotti rifle was extensively modified until its final form circa 1900. It had selective fire capabilities (single shots or burst) and also as the first successful implementation of gas operation in a rifle. Over the next few years (1903 and 1911) there were improvements to its internal functions, such as its gas operation. The rifle fired 6.5x52mm Mannlicher-Carcano ammunition fed from a 25-round detachable box magazine. The rifle, although not actually used by any army (possibly because of its extreme unreliability), was remade in Switzerland, Russia, Austria. These variations fired 8x56mm (Austria) and 7.62x54mmR (Russian) ammunition.

The Cei-Rigotti was tested by the British Small Arms Committee and was also tested by the Royal Navy. The rifles experienced difficult ejection and had high rates of misfires.
