Vortex Diamondback 4-12x40mm Tactical Scope

The Vortex Diamondback 4-12x40mm Tactical Scope features exposed tactical turrets built for dialing elevation and windage allow quick and precise bullet drop and wind drift compensation at extended ranges. 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.

Diamondback 4-12x40mm 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 sub-tensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.

Tube Size

1 inch diameter.

Aircraft Grade Aluminum

Constructed from a solid block of aircraft grade aluminum for strength.

Waterproof

O-ring seals prevent moisture, dust and debris from penetrating the riflescope for reliable performance in all environments.

Fog proof

Nitrogen gas purging prevents internal fogging over a wide range of temperatures.

Shockproof

Rugged construction withstands recoil and impact.

Hard Anodized Finish

Highly durable low glare matte finish helps camouflage the shooter’s position.

Precision Glide Erector System

Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.

Exposed Tactical Turrets

The Diamondback Tactical scopes feature tactical windage and elevation turrets with Zero Reset making adjustments back to zero easy and quick.

Precision Glide Erector System

Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.

Fast Focus Eyepiece

Allows quick and easy reticle focusing.

Fiber Optic Radius Bar

The patented fiber optic Radius Bar visually assists tracking turret rotations.

Magnification Rib

The raised rib on the magnification ring facilitates fast magnification changes in the heat of action.

VMR-1 RETICLE

Designed to maximize long distance shooting and ranging abilities, the VMR-1 MOA reticle can be used to effectively determine ranges, holdovers, windage corrections and moving target leads. The VMR-1 reticle is based on minute of angle (MOA) sub-tensions. MOA measurements are based on degrees and minutes: 360 degrees in a circle, 60 minutes in a degree for a total of 21,600 minutes. These angular measurements are used to estimate range and correct for bullet trajectory drop in riflescopes. 1 MOA will correspond to 1.05 inches at a 100 yard distance, 2.1 inches at 200 yards, 3.15 inches at 300 yards, and so on.
