This slim, low-profile design allows the Bubblevel to be mounted on most scopes without removing the scope from the rifle. It is easily visible without losing the sight picture.
The simplest, most accurate scope leveling system ever devised. Misaligned crosshairs rob you of accurate bullet placement, especially at long range, where it counts.
For the most precise long-range shooting, use the bubble level to ensure that the rifle is perfectly vertical. This will eliminate potential error caused by shooting a canted rifle. Mounts quickly and easily to the riflescope tube.
