Vortex Diamondback Tactical 4-12x40 Riflescope

Vortex Optics riflescopes boast extreme durability, high mechanical precision, and superior high-definition optics. The Diamondback Tactical 4-12x40 Riflescope was carefully crafted and meticulously designed to make this rifle scope the ideal optical solution for long range tactical applications. The Diamondback Tactical 4-12x40 Riflescope (VMR-1 MOA Reticle) brings you exceptional image quality thanks to the XD (extra-low dispersion) optical glass. The 40mm objective lens features a VMR-1 reticle that offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing. The Vortex Diamondback Tactical Riflescope comes with Vortex Optics' VIP Warranty.

Superior Optics

Diamondback Tactical 4-12x40 Riflescope lenses are fully multi-coated with XR Plus anti-reflection coatings for maximum light transmission and minimum glare on all air-to-glass surfaces. The XD glass provides higher color contrast, sharper images, and superior light transmission. The glass-etched reticle was precision etched in the second focal plane for an image that always maintains the same ideally-sized appearance. It designed to provide precise aiming even at the longest range and lowest light conditions.

VMR-1 MOA Reticle

The VMR-1 MOA Reticle is constructed in the second focal plane and maximizes long-distance shooting and ranging abilities for your Diamondback Tactical Riflescope. The reticle was marked using MOA based subtension lines for ranging, holdover, and windage corrections; the ultra-precision laser etching on the glass reticle is kept to the tightest tolerances possible. It features an adjustment graduation level of just 1/4 MOA. The Vortex’s crosshair was carefully designed for optimum balance between precision aiming and light visibility. The VMR-1 has a max windage adjustment level of 70 MOA and a max elevation adjustment level of 70 MOA.

Durable Build

Constructed out of aircraft-grade aluminum, this Vortex Optics Riflescope has a tube size diameter of 1-inch in a single-piece tube designed to maximize alignment for improved accuracy and optical performance. A tough hard-coat anodized exterior combines with ArmorTek exterior coating to help protect your scope protects against bumps, bruises, scratches, oil, and dirt. O-ring seals and Argon gas purging create a waterproof, dustproof, and shockproof body.

Internal Mechanisms

Exposed tactical turrets give you extreme control for fast and accurate elevation and wind adjustments thanks in-part to the integrated locking mechanism that prevents accidental adjustments. The Precision-Glide Erector System ensures components of the zoom lens mechanism glide smoothly and cleanly through the entire magnification range.
