Best Mounting Height for Red Dot Sights on Hunting Rifles?

April 5, 2026

Quick Answer

For a red dot sight on a hunting rifle, a mounting height of 1-2 inches above the boreline is ideal, allowing a clear sight picture while maintaining a low profile and minimizing obstruction of the shooter's line of sight.

Proper Mounting Technique

When mounting a red dot sight on a hunting rifle, it’s essential to consider the sight’s height above the boreline. Aiming too high can cause the sight picture to be obstructed by the rifle’s receiver or scope, while aiming too low can compromise the shooter’s line of sight. The ideal mounting height is between 1-2 inches above the boreline, which allows for a clear sight picture and minimizes obstruction.

Measuring the Mounting Height

To achieve the optimal mounting height, measure the distance from the top of the rifle’s receiver to the boreline. This can be done using a ruler or caliper. For example, if the receiver is 1.5 inches above the boreline, the red dot sight should be mounted 2.5-3.5 inches above the receiver. This will ensure a clear sight picture and a low profile.

Considerations for Different Rifle Types

The optimal mounting height may vary depending on the type of rifle and its intended use. For example, a rifle with a high-mounted scope may require a lower mounting height to avoid obstructing the sight picture. Conversely, a rifle with a low-mounted scope may require a higher mounting height to maintain a clear sight picture. It’s essential to consider these factors when mounting a red dot sight on a hunting rifle.
