RE: Rubbing the block on NAP Quicktune 4000
If your arrow sits even with the hole in your riser at full draw, it shouldn't hit the rest after it drops. The block of that rest should be level with the shelf as it lays down, so any arrow shot should not have a big enough fletch where it will sit level with that hole, and still contact the shelf, or the rest. Something's wrong there. Or is it hitting before the rest drops away? Then you need to adjust the tension so it drops a little quickeer.
