Red dot sight and how it works

For shooters and firearm users, red dot sight is also called as reflex sight. The red dot is produced by a non-magnifying reflector through a small LED that gives it the red color. The light is reflected on a spherical mirror and when you look into your sight, you get to see the red dot. Standard and cheap red dot sights often produce parallax or the changing position of the red dot if you look at your sight from a different angle. If you are looking for the best red dot sight for AR15, you must look for one that is parallax free.

Types of red dot sights

There are different types and shapes of red dots once you look at your sight. You can see a tube like red dot like what you see in a scope while some produces a square like image with the dot in the middle. Although it is called red dot sight, there are sights that produces green dot among others so before making a purchase, ask your local store about it. The size of the dot also varies per model. It is important to use a red dot sight where the image is visible enough for you to see and appreciate it.

Why use red dot sights when you already have a scope?

When it comes to price, red dot sights can be much cheaper than a high quality scope and if you will compare the clarity of the image and the performance, you would notice that red dot sights can do it better. As compared to laser sights, it is also safer to use a red dot sight because damaged laser sights can possibly harm the eyes (cracked lens). Modern red dot sights are also getting lighter and lighter hence it is easier to mount and to carry it around. Last but not the least, the main use of red dot sight is to help acquire target more easily and with less time needed. This is something that most scopes cannot do hence if you are hunting with your AR15, getting the best red dot sight for AR15 will make your hunting more productive.

Placing a red dot sight 

The best place to mount an AR15 is in the middle. Don’t place on the rear end of the rifle because it will be too close to your eyes and can cloud your eyesight. Since it is too close, all you can see now is the red dot and you might lose awareness of your surrounding because of that. If you have an nonmonolithic upper receiver, it is not recommended to place your sight on the far forward part because once you raise your gun to aim, the last thing you will see is your sight resulting to slower target acquisition.
