Get the right read on your shot with the Accuracy 1st Scope Level. Unlike other levels that rely on an air bubble that can change in size with elevation and pressure, the Accuracy 1st Scope Level uses a ceramic ball that is unaffected by conditions in the field. Built with aircraft-grade aluminum, this level is made to last and offers reliable readings with a 2.5-degree increment between markings. This scope level is also great for situations where you cannot level your rifle, giving you a way to account for cant in lining up your shot. Available in 30mm, 34mm and 35mm sizes and black and FDE color options, this level is the perfect addition to nearly any firearm.
