The Scotti Naval Model was an Italian prototype automatic rifle designed by Alfredo Scotti.
The Scotti Naval Model was developed in the early 1930s. It was proposed to the Italian Navy as a potential anti-aircraft weapon for sailors, specifically for targeting low-flying planes that posed a threat to patrol boats. After undergoing brief evaluation, the Scotti Naval rifle was not adopted and development of the weapon ceased. Only a few prototypes were made.
The Scotti Naval Model operated on a combined gas and delayed blowback operation, in which an underbarreled short-stroke gas piston was used to unlock the bolt and the rest of the cycle was carried out via a blowback action. The gun fed from detachable box magazines.
