Ideal mounting height for thermal scopes on rifles?

April 5, 2026

Quick Answer

For thermal scopes on rifles, the ideal mounting height is typically between 1.5 and 2.5 inches above the bore, allowing for clear sight of the target without obstruction, while also enabling comfortable shooting positions.

Choosing the Right Mounting Height

When mounting a thermal scope on a rifle, the height of the device is crucial for effective use. A mounting height that is too low can obstruct the shooter’s view of the target, while a height that is too high can make the scope difficult to use, especially in fast-paced hunting situations. For hog hunting, where speed and accuracy are paramount, a mounting height of 1.5 to 2.5 inches above the bore is recommended.

Measuring the Optimal Mounting Height

To measure the optimal mounting height, place the thermal scope on the rifle and align the reticle with the bore. Measure the distance from the top of the scope to the bore, then adjust the mounting height as needed. You can also use a laser bore sight to ensure the scope is aligned with the bore, making it easier to measure the optimal height.

Tips for Mounting Thermal Scopes

When mounting thermal scopes, it’s essential to consider the size and weight of the device, as well as the type of rifle being used. For larger scopes, a mounting height of 2.5 inches or more may be necessary to maintain clear sight of the target. Additionally, using a high-quality scope mount that is specifically designed for thermal scopes can help ensure a secure and stable mounting height.
