The Sightmark SM26008 is a wonderful product that’s different from the conventional red dot optic shape.

It sort of reminds me of an EOTech holographic sight!

The Sightmark does not use a tube-based design; it has a square-shaped window for viewing.

I agree with users that this red dot is quicker to sight with than the traditional tube design, but this can depend on your personal preferences.

When you use both eyes, you can boost peripheral vision, which provides you with a full field of view.

The Ultra Shot Plus is a great choice if you’re using shotguns, AR-15, AK, PCC, and other weapons. I use it on my AR and it hasn’t done me wrong!

Shooting Tips for Red Dot Sights

Like with any product, you should know how to use red dot sights properly.

You want to ensure that you’re on the right path when you practice with them so you can keep them well-maintained for a long time.

It would be best if you’re already comfortable using your own rifle before attaching red dot sights.

Take time to practice a lot, which will ensure that you’ll end up with the best results with a newly attached sight.

It will also keep you safe on the range in the process.

Red dots are meant for aiming and shooting. However, you should master finding targets quickly without taking the time to aim down your sights.

Train by firing at multiple targets every time the timer buzzes.

Confidence is KEY, but avoid becoming overconfident just because of a couple of good shooting sessions.

Once you acquire a good skill set of shooting and aiming with a red dot sight, keep learning and practicing until you eliminate your downsides completely.

How Does a Red Dot Sight Work?

It’s safe to assume that you already know what a red dot sight is, given that you’re reading this article right now.

But just to make it clear, here’s what you need to know about how red dots work:

A red dot sight is an optic that you attach to a gun, and it works as an aid to improve rapid target acquisition and shot accuracy.

These attachments are one of the best ones you should invest in if you want to truly improve your shot accuracy.

If you’re a hunter, mastering the best red dot sights in your arsenal can make things easier for you out in the wild.

I’ve found it easy to keep a bead on elusive targets and hit multiple targets in one area.

For those who practice at the shooting range, this is a fun attachment that will probably deliver better results compared to using iron sights.

It’s EASY to use and lets you hit steel, cardboard and paper easily.

Some budget red dot sights can even go up against the best holo sights, and that’s saying something!

Should You Use Red Dot Sights for Your Guns?

If you’re using a rifle, I highly recommend using a red dot reflex sight. These will improve your accuracy compared to using the stock iron sights.

Of course, there are various models and styles, along with different performance points and costs.

You’ll have to do the homework beforehand and list down your preferences and needs before purchasing the best budget red dot sights.

Choosing the Best Red Dot Sight Under 100

Three different red dot sights

To help you choose the best red dot sight for you, there are a bunch of factors to consider.

Make sure to take these into account before making a purchase. I did, and they helped me narrow down and refine my choices.


With red dots, it’s a common misconception to think that just because you can see the reticle, it’s already good enough.

After all, what’s the point of multiple brightness settings when all I need is just one that’s good enough for me to see?

Keeping your sight at the highest setting, assuming you use the highest one, will drain your battery before you know it.

In some cases, it might be quite pointless since the reticle may also be blurred!

Having multiple brightness settings allows you to adjust accordingly depending on how much light is available. 

Reticle and Adjustable Size

Scopes have various reticle sizes, and some even have adjustable sizes. 

Don’t forget to consider how much room your rifle can accommodate after placing this attachment.

Once you check if you have enough space, you can safely go for bigger reticles if that’s what you prefer.

Some products also use crosshairs instead of dots in the sight picture, so that’s also something to keep in mind.

Furthermore, when choosing a red dot reflex sight, don’t worry too much about its sharpness.

These dots aren’t supposed to be crystal clear compared to reflex sights!

These are only meant for you to acquire your targets easier and act as a guide. As long as you can put a dot on your target, your sight does its job.

Power and Battery Life

Some users disregard this point when looking for a high-quality red dot sight.

You can get lighted reticles that don’t use power, and you can also use red dot sights that receive energy from batteries.

Additionally, it would be best to take care of your batteries and extend their lifespan as much as you can.

If not, these can suddenly drain out while you’re out on the field or in the wild, which is something you should definitely avoid.

I’ve had my sights go out on a nighttime hunt, and I was only lucky that I had emergency iron sights on my gun.

The best practice is not forgetting to turn off your red dot sight when not in use.

Not all red dots, even the best cheap red dots under 100 dollars, have an auto-turn-off feature.

Remember to make it a habit to turn off your red dot sights after target shooting sessions.


The tube-design red dot sight is a traditional type that the older generation of shooters is familiar with.

Today, modern hunters are accustomed to using open designs when they’re out for a hunt.

A lot of the newer generation red dots use sturdy and reliable materials like aluminum, stainless steel, and any other material that’s sturdy and durable enough for harsh conditions.

But if you’re looking for even more durable models, you might want to consider getting holo sights over red dots.

You can check out this guide I made to learn more about the different rifle scope manufacturers.


Of course, you should only consider getting what you can afford and what is suitable for your situation.

If you’re a beginner, you can settle for any budget red dot sight above.

If you’re more experienced and just need some backup optics, the red dots above will serve you just as well.

Higher prices don’t always mean better quality, but you should still be wary of a low price point and be well-informed if the cheap red dot reflex sight you buy will be reliable.

If you’re looking for affordable scopes, I also have a buying guide on $100 AR-15 scopes.


Lastly, of course, if you run into problems, you can always turn to the company’s warranty program if they have one.

Warranties, especially lifetime warranties, are good ways to tell if a company promises a high-quality product.


Before the hunting season begins, it would be best to already acquire the best red dot sight for you.

After figuring out your needs and preferences, looking at this article as a guide will make things much easier for you to acquire a reliable red dot sight for your shooting needs.

Happy hunting and shooting!
