What to look for in a red dot – Buying Guide

When trying to purchase the best red dot for your Ruger 10/22, you would need to look out for the following factors;

Reticle Size

Basically, you are better off settling for a red dot that is large enough for you to clearly and easily identify your target but not too large to tamper with accuracy in target acquisition. 1-3 MOA red/green dots are the best when you are trying to enhance shooting accuracy while larger MOA dots are better if you have astigmatism or are trying to enhance the speed of your weapon during target acquisition.

Reticle Shapes and Color

Some red dots sights come with plain dots, others come with shapes such as dots with a circle or semi-circle or dots with cross hairs. Also, some red dot sights come with either green or red colors. In this case, you would need to find one that is at par with your shooting needs.

Brightness levels of the reticle and Night Vision Compatibility

The best red dot would be one that is visible and bright enough in both bright daylight and low light conditions. Also, you are at an advantage when you purchase a red dot sight with night vision compatibility because you will be able to see comfortably in the dark.

Tube shapes and sizes

You would need to choose between open sights and tube sights. Open sights are often less bulky and they provide you with an exceptionally wide field of view. This allows for easier target identification. Tube sights, on the other hand, are more durable and versatile.

Battery Performance

Generally, red dot sights are powered by batteries. The red dot is only visible when the batteries are running. In this case, you would need to purchase a red dot sight that uses readily available batteries so that you can easily replace them when they run out.

In the event that you choose to purchase a holographic sight, you should know that they consume a lot more energy thus their battery life may be shorter than normal LED red dots. Another option would be purchasing a red dot sight that has solar charging abilities as battery backup or one with an auto-off feature that significantly conserves your battery. All you need is a good quality red dot with a dependable battery performance.


At the back of your mind, you should always remember that quality is equivalent to an immersive shooting experience when hunting or sports shooting. When you get the best red dot sight, you are assured of a reliable optical performance and a durable build quality that can last you a lifetime.
