Warne Skyline Universal Bubble Scope Level Anti-Cant Device for 34mm Scope Matte Black

From MidwayUSA

Precision long range shooting has grown in popularity over the last several years. New technology has allowed shooters to successfully engage targets at distances previously thought impossible. A level reticle is vital for success at longer ranges, so the product development team at Warne have designed a Universal Scope Level that attaches to any scope tube. The Warne USL is unique from other levels because of its ability to deploy the level from an aluminum housing for use or stow, keeping the unit safe from being snagged when not in use.
