Buyers’ Guides and FAQs
What is a Red Dot Sight and What Does it Do?
A red dot sight is a bit of technology that’s designed to help shooters focus on their target. When a shooter is focused on their target and brings their sight into their field of vision, the brain notices a red dot through the lens of the sight.
This essentially means that, no matter your head position, you have a stationary red dot that will remain accurate. Red dots are ideal for high quality target acquisition at around 100 yards’ range use. In short…
The two-fold goal of a red dot sight is to:
- Help the shooter identify the distance between themselves and the target
- Utilise focus on the dot to improve accuracy of the eyeline
Here’s how it works:
The way to use a red dot sight effectively is to keep your eyes open, as they operate by using a spherical mirror which reflects light emitted from an LED light of the axis focus. This has a special coat which only reflects red light – it’s a fab bit of technology. Some argue that iron sights are superior to red dot sights, however – so make sure you shop around and do your research to find the best product for you.
Red dot sights are made with no magnification or optical distortion. This is different to lasers – which project a dot onto a target. Red dot sights are different because they are internal – in other words, they allow the shooter to see only the red dot on their own target.
The red dot sight has many advantages over different types of technology; the LED (light emitting diode) used is completely safe for your eyes, whereas a laser could provide strain.
There are three main types of red dots: reflex sight, holographic sight, and laser sight.
What is MOA?
A key specification to hunt for is MOA. This stands for ‘minutes of angle’ and is the measurement for the size of the reticle in red dot optics.
Therefore, a 4 MOA red dot sight provides a larger reticle than a 2 MOA red dot sight. This gives you a greater volume of leeway to compensate for load and range of your firearm – in this case your AR15 – meaning you have a higher chance of target acquisition.
Red Dot Sights versus Scopes
Before you’re absolutely certain you want to search for an affordable red dot sight, it may be worth knowing about the different red dot optics on the market. Hint: there’s a few.
The very first thing to do, however, is to define the key terminology you’ll see cropping up when you search for the best budget material for your AR15.
A sight is an optic without magnification, whereas a scope comes with magnification.
Magnified scopes require you to close one eye in the target acquisition process, therefore causing you to lose situational awareness. Because of the magnification, scopes may be good for accuracy within target acquisition but they certainly lose points for speed. Their main goals are to:
- Magnify the target
- Increase the shooter’s line of sight
In contrast, a red dot sight has been proven to be the fastest type of aiming reticle – this means you’ve got the largest probability of a hit on moving targets. If the target moves, a red dot sight will allow you to remain focused. You shoot with both eyes open, meaning you don’t lose out on situational awareness either.
The key differences that a scope would make over a red dot sight are:
- They’re better for magnified accuracy
- They’re worse for on-the-go target acquisition of moving targets
- They have variable power settings for easy adjustment
- They’re versatile for close and long range shooting situations
- They’re harder to hit precise moving points – they just make these points larger in the FOV
What’s the Best Brand for Good Cheap Red Dots?
Here, we’ll give you a short lowdown on two of the best brands that you should be looking at in your search for budget red dots.
You might spend ages looking at budget options to take with you to the shooting range for your target practice, but we can assure you that the search is actually very self explanatory. Many brands offer over one hundred products, and at a single click value is never too far away. Make sure you pay attention to a range of features when making your overall choice- especially brand name.
UTG is a sister corporation to Leapers, Inc. and are the manufacturers of at least two products on our top 12 list. They make everything that shooters could possibly need from a low price, from a rifle to a mount.

In this way, the company clearly has YOU in mind in any case – this is a definite plus when it comes to getting results with reliability. This company also has brilliant terms and conditions of warranty for users who may want the opportunity to return their purchase with ease.
They’re clearly one of the most preferred market options around, matching competitors on numerous levels of high performance with a highly agreeable price point.

Choose versatility with this manufacturer – as there’s so much versatility offered in their handguns today. Even their customer service has glowing recommendations – they’re a true all-rounder.
Considerations for Buying the Best Low Cost Red Dot Sight:
Before you embark on your search for a good choice, you’ll want to consider a range of features. Does your chosen gun provide you with premium conditions for windage and elevation? How about having light conditions such as an adjustable brightness setting? Maybe you even want a red dot sight that’s night vision compatible.
Whatever your needs, you want to be able to see in a wide field of view for yards upon yards. This handy guide will help you find the best red dot sights for your price range. Who knows, you might just want an iron sight instead.
Dot/ Reticle Size
The size of the red dot itself is also really key when looking for the best AR-15 red dot sight. Smaller reticles – meaning those with a smaller MOA, like a 3 MOA dot or even a 2 MOA dot, are:
- Ideal for taking precise shots at longer distances – this is because less area is covered, so the shot is more precise to the target. You have less surrounding area in the dot, so you’re more likely to get a precise ultra shot.
- Harder to see – while smaller dots are greater for accuracy on moving targets, they’re harder to focus on so you may be less able to see in bright daylight. You might, therefore, want a model with adjustable brightness or light conditions.
- Less ideal for first-timers – a larger reticle is ideal for newer shooters. However, this can obstruct target view at a longer distance.
The general rule of thumb when buying your models is to look at inches vs yards. For instance, a 1 inch red dot is ideal at 100 yards, thus a 2 inch is ideal at 200 yards, and so on. Of course, dot size is measured in MOA – so this is the key measurement you’ll need to look out for.
Another key element to buying any red dot sight is looking at the battery power, and its convenient access. If you choose a sight with special order batteries that are highly specific and quite fiddly to get in and out, as opposed to readily available batteries that can just be popped in, you’d be at a disadvantage if you can’t easily access the battery area.
Finding the right battery for you is a trade-off between high quality performance and weapon compatibility, and ease of access and convenience.
Battery power is also of the utmost importance – because the juice needs to meet the expectations of how long you want to train or use your weapon for. Most sights will have manufacturer specs for battery type and life, so this will be fairly easy to discern – however make sure you consider this before you make your purchase.
Power consumption can be affected by lighting conditions such as daylight settings, as these illumination settings may give a lower brightness level for higher natural lighting situations.
Tube Shapes and FOV
Your next priority will be to look at what offers you the best field of view. For example, sights with a lens coat will help with image quality and will reduce glare from looking at the sun – this means your accuracy will be greatly improved.
There are two key tube shapes you’ll want to think about:
Tubes look similar to a magnifying scope, and has the advantage of durability. What’s more, on sunny days you have the advantage of adjustable brightness and low light settings to make the red dot more visible for your AR15.
Open sights feature a square viewing window for you to look through. They’re generally lighter and less bulky than tubes, but they don’t go with filters generally. Open sights generally give you more FOV, though this isn’t a massive bonus if you consider you’re keeping both eyes open regardless.
Features and Specs
Now for the fun part! The features and specs of your red light dot may be what most of you are looking forward to. There are a bunch of features that can affect the pricing of your weapons, making for a deal that would suit anybody. A number of features that are key to look out for include the following:
Parallax: Some red dot sights give you the option of a parallax-free feature for your weapon, which you’d mainly prefer. This is because you here have an opportunity for higher accuracy. It’s important to note that no item is ever totally parallax free, no matter what hundreds of websites say, but you can generally be assured that industry standard means your weapons will be parallax-free from 30 yards onwards.
Adjustable Brightness: The intensity of illumination will also affect prices by manipulating the clarity on your device. To make sure you’ve got everything to do the job, you’ll want to see which devices offer you brightness settings that will take your shooting to new heights. Quite a few red dot sights, including holographic sights, will offer low light brightness levels. This may also affect the battery life so make sure you get a breakdown of battery usage to avoid a challenge.
Reticle Configurations: The best cheap option will also come with a range of features that are ideal for your shooting. An ideal red dot should be seen in both daylight and low light rooms. Many come with auto brightness adjustments, which can be handy when you want to monitor intensity settings via a brightness dial.
You’ll want to consider your model’s compatibility with night vision function, which can help you shoot in the dark or even equip you for more grave purposes – such as self defense, Whilst this gives you an edge, it generally comes with a higher price tag.
You’ll also want to consider reticle shape and color, as well as its brightness intensity levels. For instance, some dots come with crosshairs or circles to improve the accuracy of your shooting. Many have an objective lens which is fog proof – to give you the clearest sight picture possible. Even more than this, some come with a red or green dot, to give you more options for your field of view.
The size of the red dot sight’s body will greatly help you out when it comes to finding your favorite budget pick. Besides brightness levels and night vision settings, and all the other cool features you could be looking for to get unlimited eye relief, body size is actually one of the most important.
The size of the model may affect the price, and it will also affect how you use the model. While all red dot sights typically perform the same task, no matter which option you choose, your shooting needs might be affected by the types of models you go for.
For example, a smaller handgun or pistol would benefit from a smaller red dot sight – and conversely rifles would benefit from a larger one. While it’s of course, at the end of the day, down to how your models perform and whether they provide value for the price, you don’t want to be stuck with a size that doesn’t work with or for your gun or rifle.
Another brilliant starting point for your target shooting, other than viewing ability or the ability to change lighting condition, has to be the durable nature. You want a model that’s going to last you through a hundred different shooting scenarios – so you’ll want something durable. This is all the more important if you’re purchasing as part of a job for law enforcement, for example.
The reticle styles and MOA adjustment might be important features, and they may in turn affect durability, but thinking about the heavy duty features that would equip your sight for law enforcement or military use is key.
The most durable product types are made by Aimpoint, such as the Aimpoint HT or Aimpoint Pro. You can also find brilliant models for a slightly lower price, such as the UTG 3.8, but be aware that more durable reticle options tend to come at higher prices. Material can also affect durability, as some higher budget red dot sights are made of aircraft grade aluminum, meaning they’re made to last.
If all else fails, make sure the manufacturer will offer a good warranty policy on red dot reticles should you need to make a return. Some come with a multiple year warranty, so you’re covered for a while.
Co-witnessing, or co-witness is a term used to describe the mounting of red dot sights, while keeping iron sights to serve as a back-up.
This isn’t necessary or a must to ensure the best shooting, but it can definitely be helpful when searching for a red dot reticle. A co-witness is a matter of preference which generally comes down to the mount or tube size you use.
If you have a bigger tube, you’ll want to use a lower 1/3 co-witness, which allows you to align the red dot sight higher while iron sights remain at 1/3 of the overall picture.
Otherwise, you can use an absolute co-witness, which aligns rear sight, red dot sight, and front sight on the same line.
