Abstract: A lever gun has a receiver bearing the whole structure and all other components, a mechanism performing the cocking and locking functions, a trigger mechanism performing the firing function, a barrel through which the fired ammunition is guided towards the target, a magazine storing the ammunition and a lever driving and thus cocking/setting said mechanism. A divider component is positioned at the rear side of said trigger mechanism that does not face the barrel, and at which the lever is centred in order to perform rotating motion, and at least two lever arms perform transmission of motion between the lever and the mechanism, and connected to each other via movable hinges.
