Frequently Asked Questions

What are the recommended torque values for mounting a rifle scope?

For scope base screws, torque to 30 inch-pounds. For scope ring screws, torque to 15 inch-pounds. Always use a calibrated torque wrench like the Wheeler FAT Wrench for accuracy.

Why is lapping scope rings important?

Lapping scope rings ensures they are perfectly aligned and concentric. This prevents stress on the scope tube, which can lead to internal damage and affect optical performance or even cause failure.

How do you ensure the scope's reticle is level?

Use a specialized reticle leveling system, such as the Wheeler Professional Reticle Leveling System. This involves using reference levels attached to the scope and barrel to ensure the crosshairs are perfectly plumb and level.

What is eye relief and why is it important when mounting a scope?

Eye relief is the distance from the scope's eyepiece to your eye. Setting proper eye relief is crucial for a clear sight picture and to prevent injury from recoil, especially on magnum calibers.
