Vortex Flare Illuminated Bubble Level

Your elevation and windage adjustments are more effective when your rifle is perfectly vertical, and the Flare Illuminated Bubble Level from Vortex makes it easy to avoid a canted weapon. With three brightness levels and a Picatinny rail mount, it can be mounted and removed with the level on either side of the barrel — with or without a scope on your rifle. It has a recessed button control and shuts off automatically after two hours, to avoid draining the LR621 battery.
