Revenge Dial-N-Shoot riflescopes feature an advanced, fully multi-coated lens system for the ultimate in brightness, clarity, and resolution. A fast focus eyepiece provides generous field-of-view and makes reticle focus easy to achieve and maintain. Each Revenge D-N-S comes with five pre-engraved elevation dials that can be used to match the ballistic profiles (bullet drop) of most popular hunting calibers. For example, if you need to take a shot at 400 yards, you simply turn the D-N-S elevation adjustment to 400, hold the center of the reticle on target, and squeeze the trigger. The windage adjustment features a 1/4 MOA pop-up resettable dial.
