An optic mounting system, including at least some of a slide having a slide optic recess formed therein; a pair of slide insert recesses formed in opposing sides of the slide, wherein each slide insert recess is formed at least partially below the slide optic recess, wherein one or more internally threaded slide insert recess apertures is formed in each slide insert recess; and a pair of slide inserts, wherein each slide insert is positioned within a corresponding slide insert recess, wherein at least one insert fastener aperture is formed through the slide insert, wherein each insert fastener aperture is positioned so as to be aligned with an internally threaded slide insert recess aperture, and wherein at least one internally threaded optic fastener aperture is formed through a top side of each slide insert.

A firearm sighting device having a base, a first sighting lever arm pivotable relative to the base around a first pivot axis, a second sighting lever arm pivotable relative to the base and first sighting lever arm around a second pivot axis, a rear sight device fixed on the second sighting lever arm, a first positioning device for adjusting a pivot angle of the first sighting lever arm relative to the base, and a second positioning device for adjusting a pivot angle of the second sighting lever arm relative to the first sighting lever arm and the base. A rotating positioning element on the first sighting lever arm includes alignment elements that each have a positioning tip so that a distance between the positioning tip and rotating positioning element is adjustable. A buttress element on the bottom of the base interacts with the positioning tips.
