Vortex Diamondback 4-12x40 Tactical Scope

Exposed tactical turrets built for dialing elevation and windage allow quick and precise bullet drop and wind drift compensation at extended ranges. When we say precise, we mean it! These turrets track better than any bloodhound and reliably return to zero every time. A zero reset feature lets you re-index the zero reference marks on both turrets after sight in, while fiber optic rotation indicators integrated into the turrets provide a visual cue of your turret’s position.

FEATURES

Optical Features
XD™ Lens Elements - Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
XR™ Fully Multi-Coated - Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.
Second Focal Plane Reticle - Scale of reticle maintains the same ideally sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.

Construction Features
Tube Size - 1-inch diameter.
One Piece Tube - Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and water resistance.
Aircraft Grade Aluminum - Constructed from a solid block of aircraft-grade aluminum for strength and rigidity.
Waterproof - O-ring seals prevent moisture, dust and debris from penetrating the riflescope for reliable performance in all environments.
Fogproof - Nitrogen gas purging prevents internal fogging over a wide range of temperatures.
