Abstract: The present invention relates to an optical aiming device of the type having a light source and a mirror or lens reflecting or projecting an image of a reticle, i.e. a sight, to the eye of a user. The optical aiming device comprises means for attaching the optical aiming device to a weapon, such as a shot gun. The optical aiming device comprises a base part comprising the opticals and at least one attachment member for attaching the base part to the weapon. The base part and at least one attachment member are displaceable with respect to each other. The relative displacement can effectively be used to dampen the recoil force imparted to the base part carrying the sensitive opticals of the optical aiming device, e.g. by at least one force absorbing member.
