I just recently bought a horton yukon ith the dial-a-range on it . Well i dont think it is working right .When i turn the dial up higher an it doesnt do anything .Isnt the peep sight in the rear suppose to raise up an lower down as you turn the dial? if so what is it that makes it move ? If someone could post a pic of it i would really appreciate it .Or any info will be helpful .Also what type of bolts arerecommended? thx for the help .
