Q: Why do I need a bubble level on my scope?
A: A slight rifle tilt (cant) can move your point of impact, especially at long range. A bubble level removes that variable.
Q: Where does it mount?
A: It clamps securely onto the main scope tube and is positioned for quick visual checks while aiming.
Q: Will it fit my scope?
A: It’s designed for 1″ (25.4 mm) scope tubes only. Vortex make models for other tube sizes as well.
Q: Does it add much weight?
A: No—the aluminium body is lightweight and designed not to unbalance the rifle.
Q: Can I fit it myself?
A: Yes—installation is quick and requires only basic tools.
