I just replaced my sights with Copper John Deadnutz 3 pin. I have them sighted in deadnutz on. My question is there any precautions or suggestions I can do so they dont move? Has anyone had them loosen up? Its been ten years since I upgraded sights. Not sure if I need to worry about them. Thanks in advance.

Your sight body and pins should stay rock solid;I have the same sight on my bows and have never had a problem with them moving.Great sight.

Mine have never moved. Rock solid since the day I got it. As a precautionary measure, I usually check them once a week or so just to make sure the bolts are still tight.
