The Leupold Mark4 3.5-10x40 LR/T M1, Front Focal, Mil Dot rifle scope is ideal 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. -Actual Magnification: Low 3.2/High 9.5 -Finish: Matte -Reticle: MilDot -Optimum Eye Relief: Low 4.7"/High 3.4” -Unrestricted Objective Lens Diameter: 1.6" -Weight: 19.5 oz. -Length: 13.5" -Maximum Adjustment Elevation & windage @ 100yards: 65" -Field of View @100 yards: Low 29.9 ft./High 11.0 ft.
