Quick Tip: Scope Base and Ring Torque

Published on January 26, 2024
Duration: 7:53

This video provides essential guidance on correctly torquing scope bases and rings to prevent damage to firearms and optics. It highlights common mistakes like over-torquing, using permanent Loctite inappropriately, and the importance of specific torque values for different screw sizes, particularly on aluminum receivers. The instructors emphasize consulting manufacturer instructions and using a torque wrench for accurate application.

Quick Summary

Proper scope mounting involves precise torque application. For 6-48 screws, aim for 15 inch-pounds, and for 8-40 screws, use around 20 inch-pounds. Always consult manufacturer instructions and use a torque wrench. Blue Loctite can be used sparingly on quality rings after degreasing, but be mindful it lubricates, requiring lower torque settings.

Frequently Asked Questions

What is the recommended torque for 6-48 scope ring screws?

For 6-48 screws, which are common on many rifle receivers like the Ruger 10/22, 15 inch-pounds is generally considered plenty. Exceeding this can strip threads, especially in aluminum receivers.

How much torque should be applied to 8-40 scope ring screws?

For 8-40 screws, the next most common size, approximately 20 inch-pounds of torque is typically all that is needed to securely fasten them without causing damage.

Should I use Loctite on scope rings?

Blue Loctite can be used on reputable scope rings, but it's crucial to degrease surfaces first. Be aware that Loctite acts as a lubricant, so reduce torque to the lower end of the spec. Avoid it on inexpensive, soft steel rings.

What happens if I over-torque my scope rings?

Over-torquing scope rings can crush the scope tube, leading to damage and potential optic failure. This is particularly a risk with certain ring designs that have larger gaps.
