<p>Arrangement of a luminous dot sighting instrument (1) for use together with a telescopic attachment (2). The invention is characterized in that the optical system of the luminous dot sighting instrument, i.e. the portion (15) containing a light-emitting diode (28) directed against a semitransparent spherical mirror (21) and supplied with current from the electronic system, is suspended in and, against or under the action of a spring load (27), universally angularly adjustable in relation to one tube (17a) of a twin tube member (17), the other tube (17b) of which carries the electronic system (16) of said sighting instrument, said member being arranged for mounting the sighting instrument on a firearm. For adjusting a telescopic attachment (2), when such an attachment is mounted on the luminous dot sighting instrument (1), the telescopic attachment is connected with the luminous dot sighting instrument by means of a joint (4, 5; 4', 5') which acts as an articulatable joint but can be locked in adjusted position by means of locking means (6; 4', 32). After adjustment and detachment of the telescopic attachment, the joint (4, 5; 4', 5') makes it possible to reattach the telescopic attachment without need for subsequent adjustment as long as the adjustment of the luminous dot sighting instrument is unchanged.</p> |
