Bubble Level - 1 Inch (25.4mm)

The Vortex 1" Scope Bubble Level is a handy accessory for your scope. It allows you to ensure a perfectly horizontal scope. It features a green liquid level tube that is adjustable so you can set it to a position as you like.
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.
