What Is The Best Red Dot Sight And How To Pick The Best One?

Hunters who use a gun or any gun enthusiast will agree with me when I say that having the best red dot sight is crucial. If you wish to strike a target accurately, then you must use a scope.

You can just as easily use a standard iron sight. But why would you when there is a better way for aiming and shooting without making an error? The thing about a red dot sight is that it’s not just used for military purposes anymore.

A red dot sight is now commonly used for hunting and other recreational purposes too. They are perfect when you need to aim at targets that are in motion. A red dot sight is responsible for lining up your target efficiently and taking a shot with exceptional speed.

Now, let’s discuss some features of a red dot sight and then we’ll find out what the best ones are. So are you ready? Time to get started!

Red dot sight: What is it and how does it work?


When you wish to improve your aiming, there’s nothing better to achieve that than a red dot sight. What it contains is a red (or sometimes a green) circle that comes in different sizes. The dot is known as the chevron. And it’s well coordinated with the target. Once it gets aligned accurately, the shooter can pull the trigger.

A red dot sight is built with the capacity to work with multiple technologies such as fiber optics and holographic reticles. The two important things to keep in mind are the size of the dot and shape of the dot.

These two factors entirely depend on your particular skills and requirements. So it’s vital to select the red dot sight that’s right for you and not for somebody else.

Red dot sight: What are the different types?

Based on what’s popular today, there are two kinds of red dot equipped sights that hunters and shooters use. I will be discussing both of them below. So, depending on what’s best for you, you can make a better decision.

Battery-Free Red Dot Sight

This type of a red dot sight is also known as reflex sight. It is not equipped with any electronic parts, so there’s no chance of potential failure. The battery-free version has low light functionality that’s highlighted with tritium.

What this means is that a battery free red dot sight doesn’t work well under low light conditions. It’s a huge disadvantage because you will not be able to extend the scope intensity manually.

Electronic Red Dot Sight

The electronic red dot sight is comparatively more reliable in design and more efficient in functionality. The kind of durability and longevity that you get with these types of sights is truly phenomenal.

They have the ability to last for as long as 8 to 9 years despite being regularly used. It depends on the model of the sight that can last to at least 1000 hours from only 100. Such a great scope relies on the battery capacity and the power consumption of the light source.

Red dot sight: What features to look for?

Housing Configuration

When it comes to housing configuration, you can get a red dot sight in either a tube or open style. The former is a more traditional design. This kind of housing enables you to apply protective covers and filters to your lens. And such features can go a long way in making the red dot more visible in very bright conditions.

Now, let’s talk about the open style housing configuration. A red dot sight with such a design has the most basic features. So what you get are an objective window and illumination source. Open style versions don’t provide shooters with the opportunity to use filters.


When it comes to types of projection, you get two options to choose from. The first one being holographic sights while the second, reflex sights. Holographic projection illuminates the sight from the lens’ frontal region.

It also leads to the creation of a holographic style red dot, which helps to aim better. And this is done by projecting the laser-equipped diode light onto the device’s viewing window.

Reflex sights are more commonly used when you want the best red dot sight for recreational purposes. Such a sight has the ability to reflect LED light positioned in the back of the lens. And this LED light is reflected into the line of your sight.


Do you what the reticle is? It’s the red dot that we use to line up the gun with our target. Reticles are illuminated so that it is easier to shoot under low light conditions. But not all reticles are red dots. The patterns and colors vary, so you should pick one that allows you to shoot comfortably.


The red dot sight is equipped with several patterns of adjustable colors. It also gives you the opportunity to adjust the reticle’s size as well. But just remember that bigger-sized dots are responsible for faster targeting.

Battery Life

The most important factor to take into consideration is the sight’s battery life. It doesn’t make any sense if your sight’s battery runs out just when you need the reticle the most. As a result of this, your shot will turn out to be less accurate.

So keeping this mind, you should know that holographic sights consume plenty of energy. While their reflex counterparts don’t. Any best red dot sight should offer at least 1000 hours of running time before the battery exhausts itself.
