Pick up the award-winning optics of the Vortex Viper in a tough, compact size—reliable in the worst conditions. XD (extra-low dispersion glass) objective lenses further enhance resolution and deliver the true-to-life color accuracy so essential for identifying targets. Even at longer distances, the resolution of this premium, single-hinge compact will keep you scanning the landscape for one last look.


  • XD Lens Elements: Extra-low dispersion (XD) glass increases resolution and color fidelity, resulting in crisp, sharp images.
  • Dielectric Prism Coatings: Multi-layer coatings provide the clearest, brightest, most color-accurate images possible.
  • XR Lens Coatings: Vortex proprietary XR anti-reflective coatings, fully multi-coated on all air-to-glass lens surfaces, increase light transmission for maximum brightness.
  • Phase Correction: Used on roof prism models only—coating enhances resolution and contrast.
  • Construction Features
