The Sightron S-TAC 3-16x42mm Zero Stop Riflescope employs an illuminated MOA-5 reticle for intermediate-range applications where a smaller optic is needed. The MOA-5 reticle has an illuminated crosshair with marks in 2 MOA increments. The FFP model also utilizes an easy-to-set Zero-stop mechanism with 1/4 MOA clicks for tactical applications. The scope offers 70 MOA of elevation adjustments for even the longest shots. A unique flip-up lever is built into the power ring for easy adjustments on cold days.
