Product Description



The SIII 6-24x50 LR Mil-Dot provides the shooter with Long Range performance for target and field applications. With a total travel of 100 MOA the shooter has enough travel for targets well beyond 1000 yards.  Sightron's patented ExacTrack technology provides precise windage and elevation adjustments while maintaining a positive point of contact with the erector tube. From zero to the most extreme adjustments, you will never experience drift again.

The 30mm one-piece tube design features Sightron's Zact-7 Revcoat® multi-coated optical grade glass lenses which are precisely aligned to ensure maximum light transmission, color accuracy, and clarity. 

The large tactical knobs provide tactile and audible clicks with .250 MOA adjustments.  The knobs are resettable to zero and are designed for extreme weather conditions. Parallax adjustment is controlled via the side focus knob and will focus from 40 yards to infinity. 

The SIIISS624x50LRMD features a Mil-Dot second focal plane reticle.

Mil-Dot Reticle Subtensions

The Mil-Dot reticle is a mil-based reticle with a medium crosshair with thicker portions beginning 5 mils from center. There are four mil-dots extending from center to all four quadrants. The Mil-Dot reticle is versatile enough for shooting targets, steel and even hunting since the crosshair is visible in reduced light.
