Abstract: A rifle has a fixed main body, including a barrel, a receiver with an upper opening, and a breech element. A trigger group is at least partially housed in the receiver, including a trigger and a hammer device operable by the trigger. A carriage assembly includes an assembly body and a shutter group at least partially housed in the assembly body. The carriage assembly is positioned on the receiver at the upper opening and is axially movable by a user between an advanced shooting configuration and a retracted rearming configuration. Upon axial movement of the carriage assembly, between the retracted and advanced configurations, the shutter group is first moved axially in translation and then in roto-translation. The shutter group includes a central body and a command pin protruding radially from the shutter body. The command pin engages the assembly body so reciprocal interaction guides the shutter group in rotation.
