Hey, need some help here. I have a Model 30AS 20incher 3030. I put a williams FP peep on it and have the tallest white bead marbles .570 1/16th front sight. The gun shoots high at 100 yards with the rear sight bottomed out on the receiver. As i raised the rear sight no change in point of impact lower only higher. I cannot go lower on the rear. So.... I am guessing that i have to go lower on the front sight. Am on the right track? or am I losing my mind and have the good sense to quit. ny advice or criticism will welcome!
