This guide details the process of properly mounting a rifle scope, emphasizing the critical steps of leveling both the firearm and the optic. It covers selecting appropriate rings and optics, achieving correct eye relief, and the importance of precise torquing for consistent performance. The video highlights why a level scope is crucial for accurate adjustments and predictable point-of-impact.

Quick Summary

Properly mounting a rifle scope begins with leveling the rifle and then the scope itself. Use the scope's flat bottom surface for leveling against the rifle's level receiver. Ensure an equal gap on scope ring halves before torquing to manufacturer specifications to maintain accuracy and prevent grouping issues.

Frequently Asked Questions

What is the first critical step when mounting a rifle scope?

The first critical step is to ensure the rifle itself is perfectly level. This is typically done using a rifle workstation or a vise with leveling tools. A level rifle provides a stable, true reference point for mounting the scope accurately.

How do you determine the correct position for a scope on a rifle rail?

To find the correct position, consider eye relief. Place the scope so the eyepiece is a few inches back from the receiver tang. Then, shoulder the rifle and check for a full, round field of view without moving your head. This should be verified at your intended magnification.

Why is it important to level the scope to the rifle receiver?

Leveling the scope ensures that your vertical and horizontal adjustments are true. If the scope is canted, your elevation adjustments will also affect windage, and vice-versa, making it difficult to zero the rifle accurately and consistently.

What is the most reliable surface on a scope for leveling?

The most reliable surface for leveling a scope is typically the flat machined bottom of the scope body. Unlike the top turrets, which can have manufacturing variations, the bottom flat is usually true to the scope's internal reticle.

What are the recommended torque values for scope ring screws?

Torque values vary by manufacturer. For 6-48 screws, 15 inch-pounds is common for ring tops. Always consult the manufacturer's specifications for both ring bases and tops, as over or under-torquing can cause damage or affect accuracy.
