Mark 4 scopes create opportunities earning Leupold its place on the front lines in tactical situations. The Mark 4's sophisticated design delivers edge-to-edge sharpness, and excellent low-light visibility.
The maintubes are milled from a solid piece of 6061-T6 aircraft aluminum. The 30mm diameter provides enough room for extended travel of the Windage and elevation adjustments.
The oversize Windage and elevation knobs on the Mark 4 M1-10x40mm are easy to grip. Plus, you get audible and tactile feedback from the 1/4-MOA clicks. Once sighted-in, the knobs can be zeroed. Also, the elevation knob has a horizontal scale that allows you to count adjustment revolutions.
Mark 4 scopes also employ a turret-mounted focus knob that lets you adjust out parallax for specific ranges, from 50 yards to infinity, in a shooting position without taking your eye off of the target.
Comes complete with lens shade and Butler Creek Flip Open lens covers.
