04. Red Dot Sight Vs Iron Sight

As a shooting enthusiast, you will probably hear someone claiming that everyone should start shooting with iron sights to acquire the fundamentals perfectly. And no wonder, you will come to know that, many of the experts believe that, iron sights are almost obsolete now. Since I am a shooting lover, I will suggest you that, avoid the iron sight vs other optics debate and focus on your resources. If you have no budget problem go for better optics like red dot sights or other ones.

Before the introduction of red sights or other optics, shooters use iron sights. Even today, some are still fond of iron sights for a couple of reasons. Iron sights are cheaper than other optics, which is really great for beginners and those who are on a budget. They are lightweight, require no batteries, have no worry of water intrusion, easy to maintain, and clean. Above all, iron sights offer a decent point shooting reference. All these options come really handy when you are in the jungle for shooting. In fact, reports say that, for ease of use, many military units use iron sights in the jungle.

When red dot sights and other optics get introduced to the market, there was a huge transition from iron sights to other optics. Because red dot sights and other modern optics are faster in target acquire, more forgiving to parallax error, offer better range and wind estimation, offer better target identification.

Though red dot sights perform better than iron sights, they don’t come with a built-in magnifier. That means they cannot improve the range. Here, red dot magnifiers come into play.

Buying Guide of Best Red Dot Magnifiers

Best-Red-Dot-Magnifier-ReviewsWe have introduced you to the perfect red dot magnifiers. We have mentioned the most compact ones from the market. And there are other options available for you. But before jumping into the final decision, we suggest you know the basic parts or the most important facts of a red dot magnifier. Once you know the basics, you are good to find your own solution.

Lens Quality of Red Dot Magnifier

The lens is the heart of any optics. How your magnifier will perform depends largely on the lens quality. Try to choose the magnifiers that come with a multicoated lens. The multicoated lens offers you an image with great clarity.

Tube and Lens Diameter

The objective tube and lens diameter play a vital role in the performance of a red dot magnifier. With a large diameter, you will get a great field of view and see more things easily and comfortably. With a short diameter, you will get a shorter view and suffer to acquire the target easily.

Elevation and Windage Adjustments

Elevation and windage adjustments are a must for quality long-range shooting with scopes. Good quality optics will provide you with options to adjust elevation and windage adjustments. Like the good bow sights especially the excellent single pin bow sights. But these options are available with the models that come at a low price. You have to cost more to get those options from a red dot magnifier. While buying any optics, always try to avail of one that will give you extra features and accompany you for a long time. Cheap ones will not help you out in the hard condition.

The Durability of Red Dot Magnifiers

Since you are equipping your rifle with the best accessories, it is evident that you will shoot in almost all types of weather. The situation may decrease at any time in case of weather and you may have to shoot in the rain or in the sun. To face unfavorable weather, you should always choose optics that are made to overcome rough weather.

Before choosing any magnifier to make sure your chosen one has an ergonomic design and anodized finish. It should be sealed and nitrogen purged so that moisture, debris, and other material can not harm the optics. At the same time, the magnifier must provide waterproof and fog-resistant performance. You would not like to stand helpless deep in the jungle or heavy rain due to the lacking of your magnifier. And it is really great if you avail one that features shockproof facility.


Magnification plays a vital role in all types of optics i.e. night vision devices. And when you are buying a magnifier, it is evident how important magnification is. Magnification not only improves the range of the shooting but also enhances the probability to acquire a target fast.

Though there are magnifiers in the market that offer up to 5X magnification, we suggest not to be tempted for the largest magnification in the case of the magnifier. Rather, we suggest you stick to 2X to 3X magnification. Here is the reason why we suggest that.

Why You Should Avoid More than 3X Magnification

Remember you are buying a magnifier for a red dot sight. And you are not using a Vortex red dot scope. In general, good quality scopes like the night vision types have enough space to house lenses, especially so that they can catch and redirect light. That’s why scopes offer more magnification than simple magnifier and perform better with larger magnification. In the case of magnifier, they are generally compact and smaller in design and if you go for more magnification, there will not enough space to accommodate the required number of lenses.

As a result, there will be less light redirected for illuminating the reticle. In easy terms, magnifiers with large magnification perform dull in low light conditions. You will hardly see the reticle. So, it is better to go for 2X to 3X magnification.

Mount System for the Best Red Dot Magnifiers

You are buying a magnifier to improve the shooting range and cover a handsome distance. But there are scenarios where you will not willing to use the magnifier. Rather you will only want to see the target like a turkey through the red dot sight. In case of looking or targeting a very close range, it is recommended to avoid any magnifier. Otherwise, you will have a terrible field of view and it will be painful for your eyes.

With a flexible mount system, you can switch from using the red dot without the magnifier in moments. With a flip mount, you will acquire your targets quite easily and change your aim from one target to another very fast. Keep in mind that, switching from close-quarter to mid-long-range shooting is really very necessary while shooting. And you can not do that with a fixed mount system.

We suggest you use a flip mount at any cost. All the magnifiers we have suggested comes with a flip mount. This mount will allow you to quickly put the magnifier behind your red dot when it is necessary and keep it aside as well on short notice. Remember the rule of thumb, you need to put aside the magnifier when you are targeting in a close range. The flip mount allows you to do that easily.

Eye Relief

Eye relief refers to the distance between your eye and the optics. Every optics must have adequate eye relief. You may have quality optics but optics with too short eye relief is of no good. Short eye relief will be painful for your eyes. In the case of magnifiers, the same rule prevails. Buy magnifiers that come with comfortable eye relief. It will make your shooting experience great.

Another thing to keep in mind that after buying a magnifier with comfortable eye relief, you may need to explore the position of the magnifier before going for shooting. Probably you will place the magnifier on Picatinny or Weaver rails. Focus the in-between gap of the sights and magnifier. Test several times after placing the magnifier. Once you are sure, go for a shooting.


Red dot magnifiers come in a wide range of prices. Some are cheap, some are moderate and some are quite expensive. While in the market you may get confused about which one is appropriate for you. Actually, you have to choose wisely. The model will differ according to your use.

Say, you are looking for a workable magnifier to use in your range or target practice with 22lr scope. If this is the case, you should not choose a costly magnifier that offers many features. Most of the features are not necessary for you at this point.

On the other hand, if you are going for hunting i.e. squirrel hunting with scope or bird watching with a nice monocular or backpacking with your favorite monocular or combat mission, you must choose one from the latest model that offers critical features to help you accomplish the mission.

Compatibility of Quality Red Dot Magnifier

A single piece of magnifier may not be compatible with all the sights available in the market. So before buying the magnifier, make sure your chosen one is compatible with your existing sights. Generally, magnifiers and sights from the same manufacturer support each other and also perform better. If possible, try to get a magnifier from the manufacturer of your sights.


We are at the end of our best red dot magnifier reviews. Here, we have chosen the models after doing enough research to ease your decision making. We hope and wish that our detailed guidelines will enable you to have a good shooting experience with red dot magnifiers. Good luck!
