  • Description

    The Vortex 4-12x40 Adjustable Objective Diamondback Riflescope is loaded with features!  First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the cross-hairs. Look for all this and more in a riflescope you'd expect to cost quite a bit more-but doesn't.


    A Rock-Solid Performer

    The number one consideration when purchasing a riflescope is the quality of their optics. Vortex has designed their Diamondback Series with multiple layers of anti-reflection coatings on all their air-to-glass surfaces.  These important features result in bright, sharp, high contrast images across the field of view.



    • Fully Multi-Coated - Anti-reflective coatings increase light transmission
    • Single-Piece Tube - Maximizes alignment for improved accuracy
    • Waterproof - O-ring seals prevent moisture from penetrating the riflescope 
    • Fog-proof - Argon gas purging prevents internal fogging in any temperatures
    • Shock-proof - Rugged construction withstands recoil & impact
    • Hard Anodized Finish - Durable finish helps camouflage the shooters position
    • Precision-Glide Erector System - Ensures smooth operation of the zoom lens.
    • Capped Reset Turrets - Allow re-indexing of the turret to zero after sighting in
    • Fast Focus Eyepiece - Allows quick & easy reticle focusing

    Reticle Options

    The Dead Hold BDC Reticle's customized dot design helps eliminate guesswork on holdover and wind-age corrections. Good for hunting/shooting at varying ranges where estimating holdover is a concern.

      The V-Plex MOA Reticle is a popular all-purpose hunting reticle intended for a wide variety of hunting applications.
