Vortex Red Dots Sights - Ideal for rifle, shotgun or pistol applications. For example look at the Vortex Razor series - The incredible features of the Razor AMG UH-1 are matched only by its tough, tenacious performance. Absolute zero distortion and an impressive sight picture with unobstructed view ensure rapid, instinctual target acquisition. Another ideal solution is the Vortex Venom or Viper series Red Dots. The Viper Red Dot's super-low mounting height makes it the perfect solution for handguns with cutout slides. The Viper gives shooters the simplicity and speed advantage of a dot sight, while co-witnessing with suppressor height iron sights. The trade off? Nothing. The 6 MOA dot diameter gets shooters on target fast.
