Vortex Venom Red Dot 3MOA Make your AR, pistol, or shotgun even more poisonous with the Venom Red Dot sight. A 3 MOA dot promotes rapid target acquisition, while providing a precise point of aim€”getting shots down range and on target fast. The durable, machined aluminum housing ensures the unit will stand up to whatever you throw at it. High-quality, fully multi-coated lens offers a clean, wide field of view. Our top-load system makes changing the CR 1632 battery a snap and alleviates the need to remove the sight when switching the power source. The power and dot intensity controls are conveniently located on the left side of the unit. Flush 1 MOA windage and elevation adjustments are super sleek and make sighting in a breeze. Note The Venom comes with a Weaver / Picatinny mount€”weighs 1.6 ounces with mount.
