Vortex's Diamondback Riflescope Line offers professional level features at an entry level price. Named after the Eastern and Western rattlesnake species, the Diamondback series features fully multi-coated lenses for maximum clarity and light transmission. The optical quality is perfectly matched by their sheer durability thanks to a one-piece aircraft-grade aluminum tube, allowing the Diamondback to easily stand up to heavy recoil and minor impacts.
