I'm a bit unclear about your question. The 94 usually has a simple spring leaf rear sight. The elevator is a notched piece that alters the elevation of the rear sight blase to change the impact of the bullet on the target. The sight blade is on a spring arm that connects to the sight dovetail base which is the part that fits into the dovetail on the barrel to retain the sight on the rifle. The sight is generally one piece of folded spring steel except for the elevator. There are many other types of sights. On some the rear sight blade is a separate piece that is hinged on the arm of the sight. This allows the sight to lay down on the barrel for low scope mounting. Some folding sights are hinged directly to a dovetail base and elevation is accomplished through movement of a piece on the sight which contains the sighting notch. On others the sight blade is part of dovetail that is mated to a dovetail on a base that is mounted on the barrel. The mated dovetails are set at an angle upward. This allows the sight blade to slide up or down for elevation adjustment. There a myriad number of designs for rear sights and all have good points and not so good. Most sights today seem to be valued more for their low cost that usability. In fact many rifles come from the makers with no provision for mounting open sights. The optical sight or telescope seems to have completely taken over. I hope I've helped with you question, if not pleas rephrase.
