Rick at Dickson Sportsman tied my peep in with a sliding knot so I could adjust the peep up or down if needed. Well, I was only able to get the top knot to budge a little. The knots are pretty tight. A guy at BPS told me this is a junk knot and the peep will move out of position. I have the peep where I want it now and don't want it to move. Will it move with the sliding knot after shooting?
