This innovative optic comes with the added benefit of one free custom dial system (CDS) elevation dial, personalized to your specific load, muzzle velocity, hunting elevation, and temperature. With the CDS, all you need to do is range your target, dial in the distance, and take the shot, eliminating the need for calculations or guesswork.
