Some of the most advanced scope housing on the market is available in either 29mm and 35mm. SURE-LOC Scopes include three pins: .010, .019 and .029, and eight pin-mounting locations so every archer can select his or her preferred view. The highly durable and great-looking aluminum anodized body comes in orange, green, red, blue and black. Threaded front and back for the addition of a lens or sunshade, each version accepts SURE-LOC lenses and the discontinued Black Eagle lenses.
