This guide details the correct procedure for leveling a rifle scope, debunking common myths. It emphasizes that modern scope turrets are precise enough for leveling and explains the critical difference in leveling requirements between 0 MOA and 20 MOA rails. The guide stresses the importance of a level scope body for accurate tracking and dialing adjustments, advising against leveling only the reticle if the body is canted.

Quick Summary

On a 20 MOA rail, the scope must be perfectly level to the rail itself. If it is canted, any elevation adjustment will inadvertently introduce windage error because the adjustment is no longer moving on a true vertical axis relative to the bore, impacting accuracy. Modern scope turrets are precise enough for leveling.

Frequently Asked Questions

Why is it important to level a scope to the rail on a 20 MOA mount?

On a 20 MOA rail, leveling the scope to the rail is crucial. If the scope is canted, any elevation adjustment will also introduce windage error because the adjustment is no longer moving on a true vertical axis relative to the bore, significantly impacting long-range accuracy.

Can I just level the reticle instead of the entire scope body?

No, you should level the scope body. If the reticle is canted relative to the scope body and turrets, it indicates a manufacturing defect. Leveling only the reticle without leveling the body will lead to tracking errors when dialing for distance.

Are modern scope turrets precise enough for leveling?

Yes, modern scopes from brands like Nightforce, Leupold, Vortex, and Bushnell are manufactured with high precision using CNC machining. Their turret tops are typically perfectly flat and can be reliably used for leveling the scope.

What are the best tools for checking scope level?

High-quality bubble levels or machinist's levels are recommended for checking scope level. Brands like Stabila are mentioned for their accuracy. It's important to test your leveling tools to ensure they are accurate.
