ABSTRACT:
A sight for a firearm or other article which is intended to be aimed at a target or the like comprises a collimator which is mounted for universal pivotal movement on a mount mounted in turn on an adaptor adapted to mount the sight on a firearm or other article. The collimator contains a light unit located at its front end and arranged to emit a light spot towards the rear of the collimator which has an opening covered by a transparent lens. The light unit is surrounded by a transparent casing which extends in front of the collimator and has a closed end through which extends a jack pin. The pin extends into a chamber in a housing projecting from the mount and provided with adjusting screws for adjusting the angular position of the collimator relative to the mount. A locking screw is provided for locking the collimator in position once a desired adjustment has been achieved.
In use, an observer looks into the sight with one eye while viewing the whole target area with the other eye. The light spot from the sight will appear to the observer to be superimposed on a target and he can use this spot for aiming the firearm or other article at the target.
