What is a Red Dot Sight and How Does It Work?

A red dot sight is a necessary accessory for an AR-15.

It comes with many different designs and styles. Even you can find out the different performance characteristics with a huge majority of the price range, the best red dot under 100, for example.

Each red dot sight has a holographic dot which will aim and hit your target.

On the other hand, they work on an illusion technique. This means an angled piece of glass will reflect from an LED. After getting enough brightness, you can see your dot no matter how bright your surroundings are.

Is it Possible to Get the Best Red Dot Under 100?

The short answer is yes.

However, you keep in mind that in this price range, most models don't have bells and whistles which usually have in the higher-end products.

Nevertheless, you can expect that they come with reliable performance in a long time.

How to Buy the Best Red Dot Under 100

First of all, you should know that not all low-cost optics can meet your expectations.

Thus, it's essential to read this part and invest your money in a high-quality and reliable model.

Construction Quality

Durable material is a must. It should withstand tough use in a long period of time unless you want to spend another amount of money to buy a new one in a short time.

Next, a lightweight unit allows you to carry easily. This is more important for hunters who move regularly.

Battery Life

No one wants to get a red dot's battery depleted in the middle of the hunting trip. So, make sure that you have strong battery life to avoid changing it frequently.


The MOA (minute of angle) value will let you know the size of the dot. You can refer to this information in the different sites.

The average level is about 4 but some can be up to 60. To get the best view of the target, you shouldn't take too big or too small MOA.

Variable Brightness

Here's the fact:

Sometimes, the light conditions can be low.

For example, when you hunt at night, a red dot having variable brightness settings will give you a perfect brightness level.

Fog/waterproof Design

In some cases, you will have to hunt in extreme weather conditions which are not good for your performance. Thus, it's very essential for your scope to feature a fog proof and waterproof design.

Other Considerations

  • A long warranty shows the trust of the company and manufacturer in their product about reliability and performance.
  • I highly recommend a red dot which allows you to mount and get detached quickly without the support of any tool.
  • An auto shutoff feature helps you last the battery power.

How to Zero a Red Dot?

This process is very necessary to get an exact lineup and increased shooting accuracy.

Here's the step-to-step guideline to zero a red dot:

  • Set up your target about 25m (82') away.
  • Take the rest of your weapon solidly and center the sight dot on your target.
  • After shooting, let you check the point of impact.
  • The sight adjustment will be based on the bullet direction from the center of your target.
  • Make another shot of round to determine the accuracy.
  • Repeat this thing until you get the center of the target.
