Mechanical Zero

To mechanically zero the weapon, the firer adjusts the front sight post up or down until the base of the front sight post is flush with the well. Then he adjusts the front sight post 11 clicks in the direction of UP. This moves the post down into the well 11 clicks. The soldier turns the rear sight windage drum until it moves all the way to the left side and locks. Then, he turns the windage drum back (right) 17 clicks so the rear sight is approximately centered (see Figure G-23).
