In a mechanical sighting device for rifles, the front sight (6) is adjustable vis-à-vis the rifle barrel (1) as to height and sidewardly. In order to enable a height- and a sideward-adjustment independently of each other, and to guarantee at the same time a sturdy construction to be operable in a simple manner, the carrier (3) is supported slewably about the rifle barrel (1), and there is provided a finger (2) affixed on the rifle barrel (1). In the carrier (3) there is supported a setting screw (11) which crosses at right angle the rifle barrel (1), or the swivel axis of the carrier (3), respectively, and is supported on the finger (2). The foresight (6) is screwed into a bore (5) radial to the swivel axis of the carrier (3).
