Vortex Scope Bubble Level - 1" (25.4 mm) Tube

Vortex Bubble Level 1 Inch Tube

The Vortex BL1 bubble level mounts directly to the 1-inch tube of the riflescope and lets you check that the rifle is perfectly vertical when taking the shot, avoiding canting in long-range precision shooting.

It installs quickly on the riflescope tube; Vortex recommends positioning it on the side opposite your dominant eye so it stays in view while aiming.
