Quick Pick – Top 3 AR15 Red Dot Sights
Types of Red Dot Sights
We are using an umbrella term for the “Red Dot Sight” moniker. It actually refers to all types of electronic sights. For the purpose of this discussion we will cover Holographic sights; True Red dot sights; and Reflex sights.
Their specific attributes are covered more in depth lower in this article. They are very different technologies and each of them function as their own umbrella term, as there is a lot of variation on the market.
Most of this will be explained in this article; at least enough to educate you on making a purchase. The umbrella term for the purposes of this article, of “Red Dot Sight” will be used basically interchangeably with the term “Electronic” sight.
That is only for the purposes of staying congruent, as not all “Electronic” sights are actually electronic. Don’t worry, we will help you make sense of all of this.

If you really want to know if you have an inkling of interest in electronic sights you might grab one of these, prefaced by the concept that you know it’s meant as a novelty.
Once you see what it can do, you’ll realize that spending some real money on a proper electronic sight, you will get much more value from it.
It’s a lot of value for the money, but ultimately in electronic optics, you get what you pay for, so tread lightly.
- Cheap quality
- No real feature set
- Not durable
- A novelty really
We seem to take a negative approach on this one, but it should be noted, we recommend it to help get more shooters understanding the reason why electronic optics are so useful.
We believe this may enhance the shooter’s ability to gather information and understand the market segment.
Note: no one will promise this is a great experience with this sight, simply that it is a good entry point for those who really want to know what you can do with even a base level device.
Given it’s so cheap and limited in its operation, the Feyachi Reflex Sight still accomplishes quite a bit for the time and money you’ll invest in it.
Advantages of Red Dot Sights
Cowitnessing is when you can either use the iron sights or use the Red dot/electronic sight. Cowitnessing is allowed due to the open nature of the architecture, as the sights are unimpeded generally by the electronic sight.
Predictability of performance is a nice thing to have; electronic sights are very consistent and predictable. Battery life is massive nowadays in the newest models; the proven reliable technologies have matured, and your level of risk is miniscule to get into the game.
Two eyes open shooting and an easily identifiable target with a marker to make snap decisions more accurate and quicker.
Projection Type and Electronic vs Battery Powered Sights
Projection type essentially comes down to two concepts: electronically projected and illuminated by tritium/other.
There are combination sights.
Let’s talk about some of the basics:
Holographic sights are non-magnifying glass gun sights that have a holographic image superimposed upon a piece of glass through a sandwiched glass laminate arrangement and allows a user to see this image as an outline on top of a target in the optic.
Reflex sights are reflecting glass optics that superimpose an image or reticle onto the field of view as it appears in the optic.
A battery powered sight will contain a battery to feed a laser or other projection device which will provide the light source for the projected image whether it be a red dot or a reticle or other image. Battery life and conservation of power/power management has been improved dramatically since the first generation of these devices.
A tritium-based reticle is lit by a live nuclear radioactive isotope that provides light for the reticle/image. It is less effective in low light situations than a battery-based device.
First and foremost, is the fact that some items project image/reticle in green and some in red, this can have a drastic impact on how you use your device due to your own personal preference and the human eye. Green light tends to be more easily identifiable in high brightness applications, as the human eye is evolved to pick up on that spectrum of light color.
There are many different reticle types, some of the most popular are as follows:
- straight red dot and green dot
- bullseye; which features a circle around a dot
- cross; which is like a standard old scope crosshair
- Star; which is a combination of a bullseye with extensions to show the crosshair’s legs also.
- Mil-dot; which references adjustments for point of aim to point of impact
- Triangle; which places a triangle’s upper most tip directly beneath your point of impact
There are also other variants, but they change based on the maker, generally, and the application.
The style of reticle may also incorporate a difference in sizing like a 2 MOA or a 4 MOA size. MOA is the minute of angle, which roughly equates to 1 inch at 100 yards. So a 2MOA is equivalent to 2” at 100 yards 4MOA is 4 inches at 100 yards, and so on. This grows as you move out further. A 1 MOA at 1000yards is going to be 10 inches. Not that you’ll be shooting with an electronic or red dot sight at 1000 yards, but for comparative purposes, the sizing grows the further out you go to accommodate for the angular direction.
The eye relief of the Red Dot sights on a whole is open. This means that you need to think about how you are placing the sight. It’s meant to project a dot/image onto a target so that you can make a trigger pull decision instantaneously.
If you must take the time to get your eye relief adjusted by finding a distance for positioning your head, you will not be able to make a near instantaneous decision on pulling the trigger. You should be working to use a red dot or similar sighting device as a “two-eyes-open” sight.
In order to do this, you will probably be positioning it further forward than you are used to mounting a scope or set of sights. That is not true of more magnified telescopic type red dots, but it is for reflex, holographic and other open field of view sights.
An important note: Eye relief and FOV (Field of View) are not the same thing, but they are correlated to the usage of these types of sights.
Field of View
Field of View is roughly equivalent to the amount of the target that you can see in relation to the breadth of the sight you have. For scopes, this is the sight you have looking through a scope to be. For two eyes open shooting, this may be more of a moot discussion.
Eye Relief is the amount of distance between the viewing start point and your eye, and a device tube’s optics means how close is your eye going to be to the start of the ocular lens in order to properly use the optic.
Red dots (and substantially similar sight types that are covered under this umbrella as in this article), are going to be unaffected by eye relief, as they are made for both eyes open and offer a generally open architecture. There are some small variances to this rule (tubed red dots), but generally, these types of sights can be moved further down the length of the firearm because of this architecture.
A Note About Pricing
It’s not a horrible idea to buy cheap red dot/electronic sights, but it’s not a great idea either. The only real reason to buy a cheap unit is to test your desire to actually use one in the long term and to determine which features you want when you do drop more money on a unit.
You might also consider buying cheaper devices for inexpensive guns if you are spoiled by the experience of using one.
Otherwise, it makes little sense to buy a cheaper unit, because these units, while they may enjoy good reviews and have a great feature set, are less accurate, less robust, less useful than any of the moderately or high-priced models. The technology that makes up an Electronic sight is still expensive, it is not yet a cheap commodity. Therefore, you will not see premium quality units for cheap like you might see with slings or even glass-based optics.
A good general rule of thumb is at the $190+ mark in USD. At this level of cost (while not foolproof) generally separates the good quality, longer lasting units from the novelty items that are not a very good decision to buy. You truly do get what you pay for, for the most part when buying red dot/electronic sights.
The types of concerns you have with the cheaper units are as follows:
- Bad battery life/expensive batteries/drains batteries
- Plastic optics that scratch easily
- Weak housings that allow misalignments to occur
- Lack of ruggedization
- Cheap, non-calibrated adjustment
- Poor quality altogether
- Lack of legitimate mounts to keep your zero
- Poor fit and finish/attention to detail
- Bad material choices that lead to easily breaking the unit
- Not made well enough to withstand environmental aspects/normal use
Note: we cover a few lower priced items in this article, and they are “high quality” in a relative sense, but the quality level is relative to the others in their pricing tier, not comparative to the total spectrum of competitors. We almost unreservedly would not buy a unit that was lower than the $250 range and even then, we would be very selective.
This is mostly due to the quality of the materials and the longevity of the components used in the manufacture of the units. We will admit however, it may make the most sense to experiment with a lower priced unit to determine if you really do want to make the bigger purchase later.
It’s pretty hard to choose the best red dot sight because most of the measures of a fine option are subjective or material to the individual only.
There are some best practices with manufacturing and a bevy of features and details that are common place among the best sights. Choosing of the penultimate sight will rely upon a combination of what you’ve learned, what you want to accomplish and what you have on a normal activity list for this sight.
What we think we have done however, is give you the tools needed to determine the best fit for your individual needs.
In the end this is all we can hope for, because shooting sports have become something of a customization and individualization exercise of late.
This is a great trend for the industry because it allows for more passionate, loyal fans to join and benefit from the sporting aspects of shooting.
