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.
