Reflex sights are among the most popular types of sights for the AR-15. However, with so many reflex sights on the market, many gun owners simply buy what they can afford without really fully understanding how they work or what to look for in one. Read on for an extensive look at the reflex sight and the best reflex sights that are currently still available on the market today. However, if you are looking for a iron sight, click here for more!
Reflex Sights: A Brief Introduction
A reflex sight is not just an improvement over iron sights, but it also works completely differently. Reflexes utilize a reflective glass element to brighten your view while super-imposing a reticule. This allows for much greater accuracy and faster aiming.
However, many variations existed on the market not only for the optics but also for the reticule. However, they typically use electronic components. At the same time, they also incorporate other dynamics like battery life into the equation of your build.
The Criteria for A Great Reflex Sight
Before buying a reflex sight, it is important for any gun users including you to consider several aspects that makes for a great sight. Here are some aspects to help you consider that perfect reflex sight!
You will preferably want a reticule that not only makes sense to you in design, but also is on point. Units often have different sizes of reticules, which are measured in minute of angles (MOAs). The smaller the minute of angle (MOA), the smaller and more precise the reticule. Although larger reticules are easier to spot sooner, they can also obstruct your target if they are too large.
Solid Battery Life
For any AR-15 components that uses a battery, you will definitely want a long-lasting battery. Not only that, you will also want one that is easy to replace on the fly with a compartment that preferably does not require any or much tools to open. However, you will still want one that is continuously secure and will not open on its own.
The best reflex sights allows you to adjust your brightness, which is great for erratic and inconsistent light conditions. The greater the number of brightness levels, the more advanced you can get your brightness levels. At the same time, some units have an auto-brightness function that automatically sets the best brightness levels that you may prefer.
Red Dot Sights: Useful Information That You May Need
We have come up with an extra section where we feel is equally as important for you to know, but does not quite fit in elsewhere. Hence, the purpose of this section. Here are some of the most useful and equally as important information you should know about the red dot sight.
You can see how red dot sights are also some of the most popular reflex sights you can find for an AR-15 rifle. It isn’t just popular, but it is also quite common on the market too. Although it feels like sometimes red dot sights are not magic, they are still awesome feats of engineering that gives you hawk-like vision when you are out on a hunting trip or for a shootout.
While a lot of red dot sights are usually non-magnifying, the best red dot sights are usually light in weight, durable, uses battery powers quite effectively and maintain their calibration with the target quite well. It is accurate and lasts pretty well in zeroing too.
The Special Features of the Red Dot Sights
When you are looking for a red dot sight, you will want to strike a balance between particular features you want for sighting your firearm. At the same time, you will want to steer clear of getting tempted by some extra features not similar to that of a traditional red dot sight.
There are many different kinds of red dot sights that are currently available on the market. However generally, if you come across additional features such as magnification or illuminated reticule, then these features can often take the place of many primary features of a great solid red dot sight.
If you have the money to spend, go for a particular red dot sight that specifically fits and works well with an individual firearm or class of firearms. AR-15 red dot sights are a good example of this method because you then get great performance, durability and interchangeable functionality. Since that one red dot sight can usually fit a wide range of AR-15s.
Some red dot sights may have a green dot (reticule) as opposed to a red one. However, the most important thing to remember here is that the dot needs to be visible to your eyes. The dot represents the firearm’s alignment with the target you wish to hit.
Sights also have different reticule patterns and sizes. The best ones usually allows a good range of variation. This is so that you can adjust the size and pattern to one which you are personally comfortable with. Too big a dot and it can be very hard to clearly distinguish between the target. At the same time, too small a dot will serve as a distraction, which a lot of your effort is wasted on going to try to locate the reticule.
The cost of budget red dot sights can go as low as below US$50 in pricing. However, you will be strongly advised to stay away from anything below US$140 if you do not want to keep replacing your red dot sights. Anything up to around US$200 is still considered budget, but for around that price you can get some really solid sights that may need to be paired with a magnifier if you need any extended magnifications.
Some of the best sights cost around US$240 right up to over US$550 in price. However, you will have to match your specific requirements to a particular sight, otherwise, adaptability generally takes away from maximum performances.
As far as the dot size goes (MOA), 4MOA sights will usually do a good job across a variety of handpieces – especially rifles. However, these dot sizes can also help you in estimating the range of your firearm in relation to the red dot sight’s accuracy.
The most common sizes for a red dot sight you are likely to buy (as a private consumer) range from 2 MOA to about 3.5 MOA. It can reach maybe even up to 4 MOA for more professional race gun shooters and the likes of it.
All the Benefits of a Red Dot Sight
The major advantage of choosing a red dot sight over other types of optical scopes is the good performance it offers at a comparatively affordable price. What many gun owners may not know is that red dot sights are also considerably safer than sights like those that use holographic technology (holographic sights). If a holographic sight’s lens cracks, for instance, your eye may come into direct exposure to the laser. This can cause permanent damage if you are not careful.
Red dot sights also enjoy the collective advantage of their ever-decreasing weight. The best sights optimized for weight via the aluminum or aluminum alloy used in their construction is one of their leading benefits.
The ultimate benefit of having a red dot sight is that of being able to attain targets pretty quickly. As using a scope that fits well with a wide range of firearms and preferably viewing your target precisely with both eyes open (the natural way) anyway.

Choose from a precise 3 MOA dot or a larger eight MOA dot, which is perfect for those shooting at closer ranges. Windage and elevation are completely adjustable with the use of a coin or similar-sized and shaped tools.
Compared to dials, this is obviously more effort but is preferred by some gun owners who like their windage and elevation that are more secure. You may also choose whether you prefer a quick-attach Picatinny mount or a weaver rail mount too.
You also get a useful low battery indicator, and the power shuts off after eight hours of use to prevent any needless drain. When the battery does run dry, it is easily accessible from the top without the use of tools or the need to remove your sight from your rifle too.
