Forget the need for tightening in your aperture with nuts on one or both sides of your pin block! Use the Achieve XP Pro Recurve Sleeve-Lock Block that maintains consistent and secure hold on your aperture rod.
Slide the Achieve XP Pro Recurve Sleeve-Lock Block into the windage block on the sight and lock it into the same position using the machined detente. Add your preferred aperture to the Achieve XP Pro Recurve Sleeve-Lock Block and tighten it with the screw located on the front of the block.
This can be easily interchanged if you want to have different aperture choices set up and ready to go at a moment's notice.
