I have used the Deads Nuts 2 sight in the Hunter Class a few years back. Just make sure that you only have 4 pins in there. It is a nice sight, I would get the .019 pins not the .029. As far as being able to slide the sight in and out that should be fine also, as long as you DON'T move it when you are out on the course shooting. You can't adjust your sight or other things in the Hunter classes. I think there is a limit on how far the sight can stick out from your riser also. What I do when I am unsure about something is to just put my post in aimed directly at Judy or Ken because they will give you the correct answer for sure. I (and other people)may be wrong and do not know it when we give you an answer.
