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.

To use a riflescope with your firearm, you'll need a mounting base and mounting rings in addition to the scope itself. Bases attach to your firearm and rings attach to your scope. By affixing the scope mounted rings to the rifle mounted base you create a reliable, accurate, and secure sighting system. Proper spacing of the rings, as well as the ring height should be considered to ensure a proper line of sight can be established. This will maximize the value of your investment, and enhance your shooting experience. It should be noted that in many mounting applications, a professional gunsmith' s skills will be needed for proper installation.
