Common reasons to filter this way

• match the scope to your current rings or mount
• compare optics within the same mounting standard
• narrow down the selection faster
• build a more consistent rifle setup

How to choose

Start with the tube diameter required by your current setup or the mounts you plan to use. Then compare the riflescopes based on magnification range, intended shooting distance, size, weight, and overall configuration. This makes the selection process much easier and helps avoid compatibility issues.

If you are not sure which riflescope main tube diameter is right for your rifle, check your mount specification first and then choose the scope category that matches it.
