The Vortex 3-9x40 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.
The variable mid-range magnification of a 3-9x40 scope is extremely flexible; the balance of power against the efficient 40mm objective offers hunters excellent twilight performance with a comfortable sight picture in open fields and dense woods.
