Abstract: A firearm and firearm sight system includes a rear sight that changes the image of the front sight, that is, what the operator observes when viewing the front sight through the rear sight. The rear sight accomplishes this front sight image change by obscuring portions of the front sight and its shape when the operator observes the front sight looking through the rear sight. This obscuring of the front sight results in the observance by the operator of a new front sight shape. The new front sight shape represents an aligned sight picture, meaning the new front sight shape indicates the firearm sights are correctly aligned on the firearm and can then be aligned with the intended target.
