Start with incredible edge-to-edge sharpness. Add a first focal plane, illuminated reticle for fast reads at any magnification and lighting situation. Top it with Vortex's RevStop Zero System for reliable return to zero, and locking turret for fast, stay-put adjustments. Build it all around a 34mm tube that accommodates massive amounts of elevation and windage travel, and you’ve got a long-distance impact machine that’ll have you wondering how you ever shot without it.
