Since i don't have a Horton Bow i don't have to worry over such a thing[
]. I concur with those that do own them and say they leave it alone. My scope just dials in by fps at 10 and 20 yds. then u just check to make sure windage is right at the longer range. If i ever get another Cb i will use a rifle scope 4x i like very well.[8D]
