What Is a Red Dot Sight?

The red dot sight is a type of optic that has been designed to work at a close range up to a moderate range. It is a fairly simple optic type that uses a simple reticle in order to conduct a standard job. As the name implies, this type of optics makes use of red dots as the reticle.

Depending on the brand, the red dot can also be a green dot. However, for simplicity’s sake, even they are referred to as red dots. These units are fairly simple and straightforward – and they are the most useful tools for shooters who are just learning how to handle a gun.

A red dot optic generally features 1x optics – and they do not feature any type of magnification. Nothing that has been built-in, at least. For this reason, they are simply called red dots – and not scopes.

Having their origin somewhere in the mid-1970s, these dots have come a fairly long way in the last 50 years. Not only have they seen advancements in clarity, but their battery life and quality has also improved over time.

Plus, like most technological pieces, these units vary in their size. You can find one big enough to be attached to a rifle – or small enough to be attached to a handgun.

How to Shoot with a Red Dot Sight?

In order to shoot with a red dot sight, you might want to turn on the unit first and ensure that it is working. Depending on the environmental conditions, you might want to adjust the reticle brightness using the knob.

For instance, if you are shooting in conditions with low light, the reticle will look fuzzy. Similarly, if it’s too bright, the reticle will have a halo effect. This is why you need to adjust the brightness properly, to ensure that the reticle is actually visible.

If the red dot has not already been mounted, you may proceed to place it anywhere on the gun that is most comfortable for you – particularly if you need some eye relief. Now that everything has been set, you are ready to shoot – and here are the steps that you have to follow:

  • Set on your target.
  • While being focused on your target, bring your gun in shooting point.
  • Ensure that both your eyes are open for better clarity.
  • As you are bringing up the gun to shoot your target, you will notice that your reticle moves as you are aiming.
  • When the red dot reaches the point that you want to shoot, just fire.

Shooting with a red dot sight is fast and simple. The reticle is usually self-correcting – and they are also generally parallax-free (they can easily self-focus).

Red Dot Sight vs. Holographic Sight

Technologically-speaking, both red sights, and holographic sights might look the same – but in fact, they are quite different. Red dot features a LED emitter that will shoot the beam towards the front glass – one that has been coated so that the light does not go straight into your eyes.

A holographic sight, on the other hand, will use lasers and mirrors to send holograms back to you – all this without using the front glass. The image appears to be in the front, even though what you see is just a hologram.

With complications comes a fairly heightened price. For example, the best red dot sight under $100 can also be found at around $50, whereas the standard holographic sight is found at around $200.

Also, because of the less complex technology, red dots are smaller in size than holographic sights. They are the more appropriate options if you wish to install them on a handgun.

The Difference between a Red Dot and Reflex Sight

If you do not have the proper knowledge, it is quite difficult to detect the difference. Red dots, reflex and holographic sights all result in a red dot that allows you to lock into your target – but it’s the process that makes things different.

Reflex sight projects a low-power LED beam into the lens ahead. This dot will thereon hit the lens – and then be reflected back into your eyes. Providing unlimited eye relief, they are a great option for shooters who wear glasses.

Plus, they tend to have fairly long battery life, making them a perfect choice for long hunting trips.

Are Red Dot Sights Accurate?

A red dot sight functions like any other type of optic. It zeroes in on a target found at a specific distance – and for other distances, the shooter will have to compensate.

Generally speaking, red dots are made to have quick target acquisition while at a close range, with your eyes open. They are not laser beans – so they will not function for precision or long-range optics.

However, they are not perfect. A red dot has a fairly simple mechanism – one that does not magnify the target. As a result, a red dot has a higher chance of a circular error compared to a scope.

Factors to Consider When Buying a Red Dot Sight

Some red dots are more accurate and appropriate than others – or they may simply be more up your style. This is why you may want to consider the following factors before purchasing a red dot sight.

1. Housing Configuration

Depending on the model that you wish to purchase, a red dot can have an open or a tube style. The tube model is the closest to the traditional model, and it also permits for a variety of filters and protective covers for the lens.
Open sights, on the other hand, are bare and only have the basic system. These types are generally more affordable – but, at the same time, they have less space for filters. The absence of these filters can reduce the viewing experience of the shooter.

2. Projection Type

Do you want to go for reflex sight, or is a holographic sight more up your alley. Before purchasing a red dot sight, you might want to learn about which one suits your preferences the most. Some of them may be fairly expensive, depending on their type – but the best red dot sight under $200 will certainly be worth every penny.

3. Reticle Style

Every reticle is supposed to light your way and make it easier for you to lock onto your target. However, each light can look different in its own way. The red dot, for instance, can actually be green – and instead of a single dot, it can be crosshair or bullseye. Deciding on the style may not be a matter of functionality, but more a matter of personal preference.

4. Battery Life

It is crucial that you choose a red dot sight with appropriate battery life. Granted, units with a smaller battery life tend to be less expensive – but if you plan to go on the shooting range for an extended time, it can be quite inconvenient for the dot to disappear when you need it the most.

Reflex sight options generally use less battery than a holographic sight one – and a good model can last for thousands of hours before the batteries have to be changed. To preserve the battery life, you might want to turn the unit off whenever it’s not in use.

Furthermore, cold-weather shooting can also affect the efficiency of the battery – so, if the weather is particularly cold outside, you might want to carry some spares with you.

5. Mounting Type

Not every sight can be installed on any kind of gun – so, ensure that the mounting type is compatible with your gun. Some sights are universal, whereas others work better with a particular kind of gun.

Concluding Remarks

It is certainly not easy to pick a good red dot sight, considering the multitude of options out there. However, if you are a beginner when it comes to shooting, this might be a good option for you to get used to your target.

Each model comes at a different price, with different features – so make sure to choose something that suits your own preferences and budget.
