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, a hammer device operable by the trigger, and a safety member positionable in a shooting position, disengaged from the hammer device and in a safety position, engaged with and blocking the hammer device. A carriage assembly with a shutter group is positioned on the receiver at the upper opening and axially movable by the user between an advanced shooting configuration and a retracted rearming configuration. The carriage assembly includes a safety group controllable by the user, with the carriage assembly in the advanced configuration, in a ready-to-shoot configuration, in which it is disengaged from the safety member, and a safety configuration, in which it engages and keeps the safety member in the safety position.

The linear repeating firearm, with assisted ejection, comprises: means capable of recovering energy resulting from pressure exerted when firing an ammunition to move a movable assembly against a return spring, wherein the firearm comprises a stopper, a latch and a striker cooperating with a hammer (5) controlled by a trigger (6), locking means for locking the movable assembly in a compressed position of the return spring at a rear position of movement of the movable assembly, after each shot, a manually actuatable unlocking assembly (12) capable of acting on the locking means to release the movable assembly to allow the assisted return of said movable assembly to perform an ammunition reloading.

Said firearm is characterized in that the locking means are made up of the hammer (5), which cooperates with the movable assembly, to lock the movable assembly at the rear position of movement.
