SKU: VORDBK10025 Categories: ,

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.



  • 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: 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.


  • Tube Size: 1 inch diameter.
  • Single-Piece Tube: Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness.
  • 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.
  • Shockproof: Rugged construction withstands recoil and impact.
  • Hard Anodized Finish: Highly durable low-glare matte finish helps camouflage the shooter’s position.
  • Exposed Tactical Turrets: The Diamondback® Tactical scopes feature tactical windage and elevation turrets with Zero Reset making adjustments back to zero easy and quick.

Internal Mechanism Design:

  • Precision-Glide Erector System: Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.


  • Fibre Optic Radius Bar: The patented fiber optic Radius Bar visually assists tracking turret rotations.
  • Fast Focus Eyepiece: Allows quick and easy reticle focusing.
  • Magnification Rib: The raised rib on the magnification ring facilitates fast magnification changes in the heat of action.

VMR-1 (MOA) 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.
