The Vortex 3.5-10x50 Diamondback Riflescope is built to endure, perform, and excel. Its one-piece center-tube design is carefully constructed from 6061-T6 aluminum, and fitted with a precision adjustment system that allows for a generous amount of correction. The optical system is fully multicoated for a fine line of sight, and the entire assembly is then purged with argon gas for flawless all-weather performance.
With its mid-level magnification range, and a larger 50mm objective, this fine sighting system is designed to be an excellent all-around performer with outstanding twilight performance.
