Tips for Red Dot Sight Shooting

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.

Here are a couple of tips to get you started:

  • It would be best if you’re already comfortable using your own rifle before attaching a red dot sight. Take time to practice a lot, and this will ensure that you’ll end up with the best results with a newly attached sight while also keeping yourself safe in the process.
  • Red dot sights are meant for aiming and shooting. However, you should learn how to master finding targets quickly without having to take your time to aim down your sights.
  • 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, try to 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, a red dot sight is an optic that you attach to a gun and it works as an aid to improve 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 these sights can make things easier for you out in the wild, and for those who practice at the shooting range, this is a fun attachment that will probably deliver better results compared to using iron sights.

Should You Use a Red Dot for Your Guns?

If you’re using a rifle, we highly recommend you using a red dot sight. These will improve your accuracy comparing to using the stock iron sights of your gun.

Of course, there are various models and styles, along with different performance points and costs. You’ll have to do the homework beforehand and make sure to list down your preferences and needs before making a purchase.

Choosing the Best Red Dot Under 100

Three different red dot sights

To help you choose the best red dot sight for you, there are a bunch of main factors to consider like adjustability, reticle size, flexibility, the mounting room, battery, power, etc.

Reticle and Adjustable Size

Scopes have various reticle sizes, and some even have adjustable sizes as well. 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, so that’s also something to keep in mind.

Furthermore, when choosing a red dot 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.

Power and Batteries

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 if you 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 the wild, which is something you should definitely avoid.

The best practice is to not forget to turn off your red dot sight when not in use. Not all sights have an auto-turn-off feature, so remember to make it a habit to turn off your sights after 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 opened 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.

Bottom Line

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