Best Budget Red Dot Sights

Basics of a Red Dot Sight?

The red dot sight is made for use with firearms. It doesn’t offer much magnification, and it is parallax-free. You can use both eyes to acquire your target. It displays an illuminated object as the aiming point, and this is usually in the shape of a red dot. They don’t project onto the target, but they place a red dot on the target in the window. You get faster target acquisition when you use it because you only have one focal plane, and you only have to focus on the red dot and the single focal plane. 

Red dot sights are considered fast acquisition sights that are very easy to use. People use them for target shooting, hunting, tactical military and police applications, and more. Most red dot sights have infinite eye relief, so you can aim with both eyes open. They work best at 100 yards, and they usually have high-quality glass. They don’t have magnification, so they are best suited for mid-range distances. 

Red dot sights operate using an LED light on the inside that runs off of a battery that is pretty small. The dot is used to show you the target, and most of these sights have a dial or switch that allows you to adjust the brightness of the red dot. There are certain features you can look for in a red dot sight, including the following:

  • Battery life
  • Durability
  • Reticle type and shape
  • Mounting hardware
  • Activation

Field of view is another factor to consider, and most red dots come with it. They are usually waterproof and fogproof because they are built to be rugged and durable. In addition, they are often motion activated, meaning that the sight powers on when it detects motion. They also have more extensive ranges for windage and elevation, and they usually have a knob that is easy to adjust. 

What Different Kinds of Red Dots can you get when Considering Budget Sights?

You can find two main types of red dot optics, including red dots with a tube and reflex sights. Tube red dots have optics that are enclosed so that they are protected from the elements. They have a more limited field of view, but they are protected. Reflex sights are more common, and they have a wide field of view. However, the optics are not always protected from the elements. They are compact, and they are used on pistols and SBRs. 

The term red dot is used to describe a sight that projects a red reticle on the target through the field of view. The name Reflex is short for Reflector, and it uses an LED light to project the dot onto the lens that you look through. The lens works similar to a mirror, and this makes the image appear a little bit darker than it actually is. 

When you use a reflex red dot sight, you can look through the sight from different positions. The positions don’t need to be directly in line with the sight tube, which means that they are easier to use. You won’t compromise peripheral vision. This makes these sights especially useful in close-quarter tactical situations. 

Red dot sights come in a range of prices, and people often wonder what makes the expensive ones worth it. There are some differences. The more expensive red dots usually have a longer battery life, and they will be more rugged and durable. The build quality will be better, but the less expensive budget version will work just fine. 

People also wonder whether they need a magnifier with a red dot. The red dot doesn’t have magnification, and you can get a magnifier if you need one. They attach to the scope, and they help you acquire targets when you are doing the long-range shooting. The magnifier can be mounted in front of the sight or behind it. It will usually offer 2x magnification, but you can find models that give 3x or 6x. You can leave it screwed on the lens, and they often flip to the side when you aren’t using them. 

The disadvantage to using a red dot magnifier is that it takes more time to lock in on your target, and it changes the eye relief. It can also get in the way when you aren’t using it, and it might limit your field of view. If you shoot between 100 and 300 yards, you can use the flip side magnifier. If you are shooting longer ranges, you might want to use a different scope.
