This guide details the expert process of mounting a rifle scope, as demonstrated by Kyle Lamb of Viking Tactics. Key steps include ensuring a solid mount, proper torquing of cross bolts to 65 inch-pounds, using levels for precise alignment, setting correct eye relief, and confirming all connections with index marks. Proper scope mounting is crucial for accuracy and shooter comfort before heading to the range.

Quick Summary

Properly mounting a rifle scope involves ensuring a solid mount by pushing it forward before tightening cross bolts. Use a torque wrench set to the manufacturer's specification (e.g., 65 inch-pounds) and bubble levels to achieve perfect alignment. Setting correct eye relief and using index marks with a paint pen are crucial final steps for accuracy.

Frequently Asked Questions

What is the recommended torque specification for scope mount cross bolts?

The video demonstrates torquing scope mount cross bolts to 65 inch-pounds. It's crucial to always consult your specific scope mount and rifle manufacturer's documentation for the exact torque specifications to avoid damage or zero issues.

How do you ensure a scope is properly leveled on a rifle?

Use bubble levels to ensure the scope is plumb with the rifle's picatinny rail. One level can be placed on the rail, and another on the scope's main tube or a flat surface. Adjust until both indicate a level position.

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

Eye relief is the distance between your eye and the scope's eyepiece. Setting correct eye relief ensures a full, clear field of view without the scope hitting your face during recoil. It's adjusted before final tightening.

What tools are essential for correctly mounting a rifle scope?

Essential tools include a torque wrench (or torque limiter kit) to apply precise pressure, bubble levels for accurate alignment, and a paint marker for creating index marks to monitor for loosening.
