Vortex 4-12x40  Diamondback Riflescope (Matte Black)
Key Features
  • 1.0" Main Tube
  • Waterproof
  • Fogproof
  • Dead-Hold BDC Reticle
Vortex is dedicated to the development and production of unique optics with features that allow you to see the world more clearly.

The Vortex 4-12x40 Diamondback 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, and the entire assembly is then purged with argon gas for flawless all-weather performance.

Long-range target acquisition can be difficult, and having 4-12x magnification on tap will help get the job done in most cases. Twilight hunters will appreciate the highly efficient 40mm objective when the sun gets close to the horizon.

This Diamondback scope is configured with a 1.0" tube, an adjustable objective, 1/4 MOA adjustments with 66 MOA of travel, low-profile turrets, a Dead-Hold BDC reticle, and a matte black finish.

A mounting base and rings are used to attach a riflescope to a firearm. A comfortable sight picture is contingent upon the height of the rings. A comfortable cheek-weld is the result of properly positioning the scope over the receiver. Mounting the scope close to the receiver is preferable, yet scopes with larger objectives need higher rings so the front bell can clear the barrel. It should be noted that in many mounting applications, a professional gunsmith's skills will be needed for proper installation.
