The Black Jager 30 mm Scope Bubble Level is a precision optical accessory designed to eliminate cant (tilt) error when mounting or using a rifle scope. It attaches directly to a 30 mm scope tube and provides a clear, alcohol-filled vial to visually indicate when the scope (and rifle) is perfectly vertical. Use of this level helps maintain shot consistency, especially at longer ranges, by preventing drift due to cant.
Key Features
-
Designed for 30 mm scope tubes — fits directly onto a standard 34 mm outside-diameter scope body.
-
Alcohol / spirit-filled vial — the bubble is free to move and stable under temperature variation.
-
Machined aluminum body — durable and lightweight, typically anodized in matte black for corrosion resistance and low reflectivity.
-
Low-profile design — built to minimize interference with turret knobs, rings, or accessories.
-
Single-bolt or hinged mounting — easy to install or remove without full disassembly of your scope setup.
-
Clear, high-visibility bubble — ensures you can see the bubble in many lighting conditions.
-
Precision alignment — aids the shooter in ensuring vertical alignment before each shot, reducing cant-related horizontal errors.
-
Lifetime warranty / guaranteed quality (if offered by manufacturer)
