Abstract: A see-through periscope for sighting-in optical sights or open sights by co-aligning one type of sighting system with the other type. The small see-through periscope is preferably used with firearms that have two conditions: (1) the rifle must be equipped with open sights, and (2) a gap must exist between the front of the optical sight and the rear open sight where the periscope can be mounted.
