Riflescope bubble

Rifle Scope Level – 25.4, 30 and 34 mm

A rifle scope level (also called a scope level or anti-cant bubble level) helps you detect whether your rifle is tilted to one side. This is particularly relevant for precision shooting and longer shooting distances, where cant can affect the point of impact.

Choose the Correct Tube Diameter

The level mounts as a ring around the scope’s main tube. The product is available in versions for 25.4/30 mm and 34 mm. Check your scope’s actual tube diameter and make sure there is enough space for the ring before selecting a version. A scope with a 25.4 mm (1-inch) tube does not have the same tube diameter as a 30 mm or 34 mm model.

Check for Cant with the Bubble Level

The bubble provides a quick visual reference so you can check your rifle’s sideways tilt. It is a practical accessory for hunting, target shooting and long-range shooting, but does not replace correct scope setup and checks.

Mounting on the Scope Tube

The ring attaches around the scope tube using the included Allen key. Make sure the level is mounted at the correct angle relative to the scope’s vertical reference, and follow the relevant tightening instructions to avoid damaging the tube.

Frequently Asked Questions

What Is a Rifle Scope Level Used For?

It shows whether the rifle is tilted to one side, allowing you to check for cant before taking a shot.

Will It Fit My Scope?

Measure the main tube’s diameter and select the appropriate version: 25.4/30 mm or 34 mm. Also check the available space around the tube.

What Does Anti-Cant Mean?

Anti-cant means helping to prevent sideways tilt. The bubble level provides a visual reference but does not straighten the rifle itself.

Does the Level Need Adjusting During Installation?

Yes, its position should be checked against a true vertical reference so that the bubble level provides a meaningful indication of the rifle’s cant.
