Instructions
Separate the halves of your rail mount scope rings and attach them to your scope with the Allen wrench provided with the rings. Do not completely tighten the rings.
Loosen the retention screws at the base of the scope rings so that you can spread the mounting bracket--also located at the base of the rings--apart.
Align the retention screws with the slots across the rail mount and position the bracket over the sides of the mount. Secure the bracket by tightening the screws.
Position your tactical scope to give you adequate eye relief and so that the scope crosshairs appear straight up and across when viewed through the scope. Finish tightening the screws on the scope mounts.
