The Moschetto Automatico Revelli-Beretta Mod. 1915 was a self-loading carbine that entered service in 1918 with the Regio Esercito. Designed as a semi-automatic carbine, the weapon came with an overhead inserted magazine, an unconventional design based on the simplicity of allowing a spent round to be replaced using assistance from gravity. The gun was made from half of a Villar-Perosa aircraft submachine gun.
