ZEROLNG:
Select the reticle you desire by turning the reticle selector knob and set the intensity at the best position for you .With the E/D sight mounted, rest the gun on a solid support and aim at a target 50 to 100 yards(or meter)away.Test shots should be done in the same conditions to achieve maximum accuracy for adjustment, for which the use of firm rest for firing and same type cartridge is recom-mendable. Each click adjustment moves the point of impacby 1 MOA(approximately 1"at 100 yds, 1/2" at 50 yds.)
