I wrote a comprehensive review on a high end scope where I explained Parallax in detail. Parallax is an interesting phenomenon which I'm sure cheaper and knock off red dots are not immune from. There are magnifiers for red dots, I had one on my Holographic red dot, it adds significant weight, and not a viable option for a light weight build. Red dot objective lens is usually not magnified, choosing the right MOA for a target distance is important. Generally, anywhere from 1-6 MOA is what will be offered in popular reflex red dots. For tight groupings a smaller MOA is ideal, which is why I opted for Venom 3 MOA. One MOA is 1" at 100 Yards or 0.5" at 50 yards or 2" at 200 yards. MOA is minutes of angle, it is a reference of size in relation to distance.

Personally I prefer a simple red reticle red dot, Vortex Venom is available in red reticle at either 6 or 3 MOA. Reticles come in different shapes, sizes, and colors. Red dot reticle is an option which is far too subjective. If you look at a red dot lens from the muzzle side, you will hardly be able to see the reticle at all. Otherwise, visibility of the reticle would be hampered or nonexistent depending on light conditions. This is by design, to reflect the reticle back to the operator, and prevent other natural light frequencies to flood out the reticle on the objective lens. The objective lens is tinted to help reflect the wavelength of LED output, at the same time blocking specific spectrum of light. Some red dots depending on design, bounce light between multiple lenses before reaching the objective lens. A light emitting diode (LED) is the primary light source emitting a red wavelength of light, projecting on a tinted objective lens. There are different types of red dots, the most popular similar to this Vortex Venom, is a reflector sight or reflex type. What exactly is a red dot and how does it work? To pick the right red dot, you need to be informed how a red dot works, and some of the basic terminologies you will encounter from marketing data. Understanding the application for which you will be using a red dot and the type of red dot is imperative. Choosing the right red dot is a challenge with so many different manufacturers offering a variety to choose from including Vortex. However, I do know a few people who went down this route to only regret their decision. Personally, I have never owned a knock off and will not waste my time testing and reviewing one. Word of caution, you get what you pay for, do not be surprised if the knock off fails or just doesn't perform as expected.

There are a lot of imitation red dots from overseas flooding the market at a fraction of the price. There are many optics options, specifically red dots to choose from these days. None of the high end red dots I own fit the weight requirement so after some research, Vortex was a clear winner for me for a number of reasons I'll digress below. Having used a variety of high end red dots from known reputable manufacturers, I wanted to try something different and more compact to shed as much weight as possible for this 3-Gun build. There are lots of red dots to choose from at different price points. Mounting a huge NightForce or Sightron Scope I have on my long riles is just not an option for this light weight competition rifle, a compact micro red dot is preferred. Hence, the Vortex Venom’s superiority to the other red dot sights.As part of my 2017 reviews, I'm going to discuss the Vortex Venom 3 MOA Red Dot. These few reasons and many more make the Vortex Venom viable, versatile, accurate, and durable. Since the Vortex Venom red dot sight comes with both 3 MOA and 6 MOA, and larger dot sizes are good and perfect for quick acquisition shooting while the small dot is designed to take accurate shots. The Vortex Venom 3 MOA is also a lot sharper, crisper, brighter, and more accurate than several other 3 MOA I have used on my pistols. I have also discovered that the venom red dot is a lot easier to operate on my 34 MOS than most other red dot sights, the viper inclusive.

The Venom red dots 3 & 6 MOAs provide you with a 1X magnification, compact, and parallax-free red dot sight that is thoroughly designed for precision, accuracy, and perfection. The venom red dot comes with a 3 MOA and a 6 MOA options, giving you the chance to choose the red dot size of your choice and preference. The reason why the Vortex Venom red dot is superior to the vortex viper and every other red dot sights out there is numerous and are not far-fetched.
