Best mounting options for thermal scopes on AR-15s?

April 5, 2026

Quick Answer

The best mounting options for thermal scopes on AR-15s include Picatinny rails, M-LOK, and KeyMod systems, allowing for secure and versatile attachment. These options provide a wide range of adapter and accessory compatibility. Proper mounting ensures stable and clear thermal imaging.

Choosing the Right Mount

When selecting a mount for your thermal scope on an AR-15, consider the type of rail system your rifle features. If your rifle has a Picatinny rail, look for a thermal scope mount designed specifically for this system. For M-LOK or KeyMod systems, choose a mount with compatible adapters to ensure a secure and stable attachment. A good rule of thumb is to choose a mount that allows for easy adjustment and re-zeroing of the thermal scope.

Thermal Scope Mounting Height and Offset

The mounting height and offset of your thermal scope can greatly affect its performance and usability. Aim to mount the thermal scope at a height that allows for comfortable use with your existing optical or red dot sight setup. An offset mount can also be useful for achieving the best possible thermal image quality by minimizing obstruction from other accessories. Typically, a 20-30mm offset is sufficient for most AR-15 applications.

Tips for Proper Thermal Scope Mounting

When mounting your thermal scope, ensure that it is securely attached to the rail system and levelled properly. This will prevent any image shift or distortion caused by an uneven or loose mount. Additionally, consider the weight distribution of your thermal scope and any other accessories attached to the rifle, as this can affect the overall stability and balance of the rifle. By following these guidelines and choosing the right mount, you can achieve a stable and clear thermal image, ideal for hunting hogs or other nocturnal game.
