I just got the new Vipertec in the mail and I went to sight it in and I have run out of verticle adjustment. At 40 yards I have to hold the top of the level buble and it is right on. Is there any way to move the nock point or rest to gain some adjustment. The bottom of the sight is getting close to the arrow so I don't think I can move the sight down if there was room for it..

This is the first time I have run into this problem. The bow is tuned perfect and shoots straight all the way out to 40 yards but I need more room on the sight.

Any tips?
