ABSTRACT:
A self-aligning flip-up mechanism for aiming devices for use with firearms. The mechanism folds the aiming device into the contour of the firearm during non-use. The mechanism is spring-loaded and flips into a vertical operational position with a simple movement of a finger or thumb. The mechanism causes the aiming device to self-align itself as it moves into an operational position. Vertical position repeatability is assured by the location of alignment surfaces in the sight which come into contact with alignment chamfers.
