How to tell if my scope rings are too high?

Measuring Scope Ring Height

When checking scope ring height, ensure the rifle is on level ground and the scope is properly aligned with the bore. To do this, use a bore sighter or align the scope with the rifle’s iron sights. Next, place a ruler or a measuring device on the rail or base, with one end resting near the scope. Measure the distance from the rail or base to the scope’s objective lens. A standard scope ring height is about 0.5 to 0.75 inches above the rail. If the scope is too high, the rifle’s line of sight will be obstructed, affecting accuracy.

Adjusting Scope Rings

To adjust scope rings, you’ll need to remove the old rings and install new ones. When choosing new rings, select ones with the correct height and type (aluminum or steel) for your rifle and scope. If your scope rings are too high, you may need to use rings with a lower height or a Picatinny rail adapter. When installing the new rings, make sure to tighten the screws evenly and avoid overtightening, which can damage the scope or the rifle’s rail.

Tools and Techniques

To ensure accurate scope ring installation, use a scope ring tool or a Allen wrench to tighten the screws. You can also use a bubble level to ensure the rifle is perfectly level. When aligning the scope, use a laser bore sighter or a scope alignment tool to ensure the scope is properly aligned with the rifle’s bore. Remember to check the scope’s warranty before making any adjustments or installations.
