I'll almost bet ya that's what it is.....take the dial apart, you'll see what I'm talking about when you get into it. It's a dial stop that does just like what it sounds....it stops the dial in the same postion when you turn it. If it's equipped w/ the 4 fletch, maybe try to contact Grayling and see if you can get the 3.....OR.....turn the arrow in the clamp and hope you get them where you want it.
