Instructions to remove the rear leaf spring and iron sight:
a. securely hold the weapon in a rifle vice or bench vise (be careful not to crush or bend the receiver when clamping it in a vice).
b. raise the rear leaf sight to the highest elevation setting (normally 800-1000 but this varies weapon to weapon)
c. place the end of a flat bladed screw driver (or other similar tool) into the central groove near the hinge point of the sight leaf. A gentle tap on the screw driver with a rubber mallet is enough force to pop it free. During the mallet strike, the objective is to compress the leaf spring and force the axis pin out of the guide slot underneath. Wrap the leaf sight with a rag to prevent a forceful ejection and possible injury.
d. remove the leaf sight spring first and then rear iron sight. Store them together, you will not need the leaf spring unless you reinstall the iron sight.
