Key Features of Vortex Venom Red Dot

After thoroughly reviewing the Vortex Venom, I’ve listed down these 10 standout features that make it an awesome optic.

  1. Red Dot Reticle: Like most reflex sights, the Vortex Venom is equipped with a 3 MOA reticle with adjustable brightness, providing a clear and illuminated aiming point for quick target acquisition in varying light conditions. 
  2. Dot Size Options: The Vortex Venom offers two dot size options—3 MOA and 6 MOA. This allows users to choose a reticle size that suits their preferences and shooting needs. I have both versions. I use the 3 MOA red dot for my pistol for short-range engagements. For my rifles, I use the 6 MOA one. 
  3. Compact and Lightweight Design: Made of aircraft-grade aluminum, the Vortex Venom is designed to be compact and lightweight, making it suitable for a wide range of firearms without adding significant weight or bulk. The low profile allows me to use the Venom in tandem with my iron sights or with some other optic such as a rifle scope or night vision scope. 
  4. Durable Construction: Vortex is known for producing optics with robust construction. The Vortex Venom has a durable, shock-proof machined aluminum housing that ensures durability and light weight. Its ArmorTek Ultra-hard, scratch-resistant coating protects the exterior lens from scratches, grease, and dirt. Rubber o-rings seals prevent moisture from seeping in, making the Venom waterproof and ideal for shooting in bad weather.
  5. Multi-Coated Optics: The lens is fully multi-coated to provide a clear sight picture, reduce glare, and enhance the brightness and consistency of the reticle. Due to the glass clarity, I have great visibility in different lighting conditions.
  6. Adjustable Brightness Settings: The Vortex Venom features adjustable brightness settings, allowing users to adjust the intensity of the red dot according to their preferences. It has 10 brightness level settings; in manual mode, the brightness of the dot can be easily controlled with a dial at the left side sight.

    In addition, the Vortex Venom features an automatic mode that automatically controls the dot brightness and intensity depending on the ambient lighting conditions.
  7. Unlimited Eye Relief and Parallax-Free Design: The large viewing window is one of my favorite features of the Venom. The oversized lens allows a clear, wide, unimpeded field of view of the target and the surrounding areas. A parallax-free design ensures that the reticle remains on target even when the shooter’s eye position changes, enhancing accuracy and ease of use.
  8. Tool-Less Windage and Elevation Adjustments: Making adjustments for windage and elevation is fast, easy, and simple because doing so does not require any tool. Zeroing and adjusting can be done quickly on the field.
  9. Battery Life: The Vortex Venom is powered by a single CR1632. It has a considerable battery life of 3,000 hours in the lowest brightness setting and 150 hours at its highest setting. While it ensures that the sight remains operational for an extended period before requiring a battery replacement, the Venom’s battery life is considerably lower than some top-quality sights. The Holosun series, for example, has a battery life of around 50,000 hours.

    Without a sleep mode, you need to manually switch on the Venom. As long as it stays switched on, it continues to draw power from the battery.

    The Venom has a top-load battery compartment, which makes changing the battery in the field fast and easy. I don’t have to remove the sight from my firearm; all I need is to remove the battery cap.
  10. Versatile Mounting Options: The Vortex Venom is compatible with various mounting systems, offering flexibility for users to install the sight on different firearms. When purchased, it comes with a low rail Picatinny mount that clamps to a slotted spec base rail. Also included in the box is an optional riser mount.

Its robustness is impressive, with a build that’s resistant to rust, shock, and water. Additionally, the sight is compact and lightweight, making it easy to mount and carry on various platforms.
