Are you a gun enthusiast? If you use a gun for target practice or hunting, you probably understand that having a good sight is essential to be able to accurately hit a target. Traditional iron sights are surely effective but red dot sights offer way more speed and precision.
For those who don’t know, a red dot sight is a non-magnified, illuminated sight that can be equipped to a gun or rifle. The red dot is actually created by an LED light which reflects against a small spherical mirror and gets projected directly in user’s line of sight to facilitate aiming.

People usually shell out all their money for guns and overlook accessories but red dot sight is an important one and requires closer attention. For those looking to buy one, this handy guide will be your one-stop source for information.
Here, you will find all about their types, benefits, drawbacks as well as the best models to choose from. So, stay tuned and get ready to shop the best red dot sight for your needs.
What Types of Red Dot Sights Are There?
Red dot sights come in many shapes, sizes and dot patterns. The ones with ‘tube’ style look a lot like telescopic scopes while the ones with ‘open’ style have a square-like shape. The housing of tube style sights is such that it allows the shooter to apply filters to the lens so that it’s easier to see the red dot in bright sunlight.
However, the open housing configuration consists of only the bare basics and there’s no room for filters to enhance viewing experience. Also, their sizes differ from small to large. The dot sizes are measured in MOA (minutes of angle) and 1 MOA covers roughly 1” area on a target 100 yards away.
If the dot size is too small, your eye won’t be able to pick it up fast enough and conversely, if it’s too big, the target may look obscured when shooting from large distances. A basic 3 MOA dot generally works well for an all-purpose gun.
The dot pattern or reticle is largely personal preference and has no technical significance. The pattern can be like dots, like crosshairs or even like bull’s eye. Some patterns are adjustable also so that you can have a greater variety.
Benefits of Best Red Dot Sight
If you get the best red dot sight and combine it with the best laser scopes, aiming will be as simple as placing the red dot on the target. It can also help determine your exact distance from the target. The more sophisticated red dots even offer an audio alert so that you can make the necessary adjustments to make your bullet strike the target.
With features like incremental wind and elevation adjustments, they have the capability of handling any error in aiming. This automatically saves you time and effort. Other than this, make sure that the model you choose has the features suitable for your purpose of use.
For instance, if you hunt at night, the reticle should support low light settings and have night vision compatibility. Also, the model should be compatible with the type of gun you use. Not all sights are compatible with a gun type. The best ones also have comfortable size, weight and long battery life.
A good sight can offer thousand hours of usage before the battery life diminishes. If, on the other hand, it has a short battery life, chances are that the light will go out by the time you are getting ready to aim. And this is especially common when shooting in a cold environment.
Downsides of Red Dot Sights
The only disadvantage is that most red dot sights require that the guns used should be custom cut to permit installation. This kind of work then involves extra cost on your end.
