Best Red Dot Magnifiers: The Complete Guide For Buying

When shopping for a magnifier, it can be difficult to choose. With all of the different features and brands out there, it’s hard to know which one is best. Gone are the days of awkward, heavy glass magnifiers. Nowadays, you can get an easy-to-use, lightweight red dot magnifier that will make your day-to-day tasks easier. Don’t waste your time looking for hours! We did the research for you and found some great options for you to consider. Read on to learn more about what makes them great and how to decide which one is best for you.

What is a red dot magnifier?

Red Dot Magnifiers

A red dot magnifier is a red dot sight with a magnifier mounted either in front of or behind it. Because it does not have magnification, the red dot is particularly well suited for close-range shooting. Although the vast majority of screw-in magnifiers have a magnification of around 2X, there are models available with magnifications of 3X and 6X. At all times, it should be screwed onto the rifle in order to avoid emergency situations in which the lens is forced to be screwed on immediately, which can cause your lens to become misaligned.

At close range, the magnifier has the potential to reduce the accuracy and speed with which the red dot can identify a target, which is problematic. In order to avoid this, flip-side mounts are used to attach magnifiers. The use of a flip-to-side mount eliminates the need for the shooter to look through the magnifier when using the red dot. To magnify your red dot when necessary, simply flip the magnifier into position with the flip-to-side mount and lock it in place.

The primary use of the red dot magnifier

When it comes to overall use, it's important to note that the Red Dot Magnifier is primarily the first-aid product. If you've ever needed to protect your eyes from a head trauma or some other form of serious injury, then this is a pretty good first choice. This product is also great for reading on a plane or in a dark theater. It's a great choice to have in your kit if you're traveling abroad. The majority of these types of accidents occur when traveling, so it's smart to keep this product on hand for times when you might need to access emergency eyewear.

If you’re using it primarily for health and safety purposes, a first-aid magnifier is a great tool to have on hand. These types of magnifiers are ideal for reading a small chart or application for someone who is visually impaired.

Things to consider before purchasing red dot magnifiers

In addition to magnification, mount type, eye relief, weight, and durability, there are some other factors to consider and look for when purchasing a red dot magnifier, such as:

Tube and Lens Diameter

When buying a red dot magnifier, size is the most important factor to consider. While lenses of different sizes are generally accepted to be used for different types of magnification, tube and lens diameters are a matter of some debate. What they do mean, however, is that you should consider how big a tube and the focal length you need to see the detail in order to select the right device.

A red dot magnifier's performance is dependent on the objective tube and lens diameter. A larger diameter gives you a wider field of view and allows you to see more of your target area. A smaller diameter, on the other hand, will give you a narrower target window and allow you to increase your accuracy downrange.

Red Dot Magnifiers

Magnification

When purchasing an attachment to use alongside a red dot optic, you can choose from a variety of magnification options. The most common will be a 3x magnifier, which we recommend. Some manufacturers also sell 5x or 6x magnifiers, but if you want to use it at really long ranges, we recommend getting a scope instead of a red dot and a magnifier because the combination of the two will not be as efficient or accurate.

The most efficient distance for average red dots without a magnifying device is up to 100 yards (90 meters), which a 3x magnification attachment increases to 300-350 yards (275-320 meters). The main reason you should use a red dot and magnifier combination instead of an ACOG sight (which also provides magnification) is that it allows for an easy switch if you're using a flip-to-side mount, and it's less expensive than most ACOG optics.

Compatibility

For magnifying lenses, compatibility is important. While it’s a good thing that there is a variety of magnifiers available, it’s important to make sure that the lens that you are getting fits your needs.

Your threshold, the distance that the light needs to reach your eyes, will determine what magnification you need. If you have a good tolerance for light and your red dot magnifier is a sharp lens, it will likely be a perfect fit. If you don't have a high tolerance, you may need a magnification closer to 40X or even closer. If you don't have the need for a powerful lens, you may want to consider a more narrow lens. You can check the compatibility of a lens by looking for a magnification factor, which will tell you how the light will reach your eye.

Mounting

When it comes to a red dot magnifier, you will want to be able to adjust the height for a comfortable viewing experience. Most red dot magnifiers have an adjustable stand and a chain on them, so you can adjust the magnification level, too. There are two major brands you will need to look for when purchasing a red dot magnifier: Thermosynd and Zedcor. Both of these brands offer various magnifier options to choose from. Thermosynd offers multiple magnifiers stands with different numbers of adjustments available, so you can find one that best fits your needs. Zedcor offers easy mounting for your red dot magnifier. The mounting bar at the bottom of the magnifier features a quick release so you can change the height quickly and easily.

Eye relief

When first attaching your magnifier, one of the most important things to remember is to properly set up the eye relief distance. When set up incorrectly, it may impair your ability to see targets with the red dot device. In most cases, you should have at least several inches of eye relief for maximum efficiency, but we recommend that you experiment with various positions and distances to see which one works best for you.

Prices

Red Dot Magnifiers can range from a couple of bucks all the way up to several hundred dollars. We found that some red dot magnifiers are more expensive than others, but they all get the job done. If you just need a red dot magnifier to read smaller print, this may be the best option for you. However, if you’re using your red dot magnifier to look at your laptop screen for extra magnification or to see close-up objects, a cheaper red dot magnifier might be sufficient.

Some red dot magnifiers have a higher lumen rating than others, which means they shine more light than other units. Although a higher lumen rating can be beneficial if you have low vision, most people with normal vision won’t notice much difference between high- and low-lumen magnifiers.

How to choose the best red dot magnifiers for your specific needs

There are many different magnifiers out there that cater to different people in different ways. Some require you to tilt your head back to see the magnifier. Others have a pop-up feature. Still, others have a zoom function so you can zoom in to a specific area. We tested all of these features to find the best ones for you.

The UltraSharp MK2 Magnetic Red Dot Magnifier from Best Review is the ultimate way to view the world without straining your neck. What makes it the best choice for everyone is its adjustable click and portable design. This red dot magnifier, which is compact enough to fit in your pocket, has a magnifier that is about a third of the size of a traditional magnifier.

Final thoughts

A magnifier will come in handy if you're using a red dot sight for anything other than close-quarter tactical scenarios. The most significant shortcoming of these types of sights is the lack of magnification, which these devices address.

There are numerous red dot magnifiers available on the market. Most have a 3x magnification, which is the best compromise for most shooters and hunters. If you want to save money, consider a red dot magnifier combo, in which the manufacturer sells both the sight and the magnifier as a package deal, saving you a few dollars.

 

FAQs

What is a Red Dot Magnifier?

In a word, the red dot magnifier is a tiny riflescope with an illuminated reticle that can be used for hunting. You can attach it to your riflescope or pistol scope for nightfighting purposes, and it will provide you with an additional magnification function.

As a result, they are often referred to as "red dots with amplification" by some. For the most part, the physical dimensions of red dot magnifiers are identical to those of their non-magnifying counterparts.

The addition of fixed magnification capabilities, on the other hand, means that they should be treated as independent optics and positioned level on top of the gun's barrel-in other words, you'll need a QD mount for them! To be sure, some manufacturers do not adhere to established guidelines and design their red dot magnifiers to be used as "standalone" optics without the use of a riflescope host, at least in theory.

The second advantage of such "standalone" red dot magnifiers is that they can frequently be positioned behind your riflescope and used as a separate sighting system. Please keep in mind that this configuration is less efficient than the previous one and that it will require some trial and error to get peak performance (you will also need flip-up covers for the front and rear lenses of your scope).

Does the magnifier go in front or behind the red dot?

It's best to keep the magnifier behind the red dot when using it. The gap between them should be no more than 2-3 millimeters (the closer, the better). While some units enable you to set them side by side, I would advocate moving the magnifier behind your RDS for two reasons:

Any magnifier has a magnification level of at least 2X, which allows for more precise aiming while using both eyes open at the same time. You can utilize a fixed magnification power in conjunction with a variable red dot intensity control to achieve the desired result.

In situations where lighting conditions are less than optimal, this might be a significant disadvantage (e.g. low light or in foggy weather). However, by using a red dot magnifier in conjunction with your RDS sight, you will be able to take advantage of the entire variety of aiming aids available to you!

Does the red dot magnifier change zero?

Both yes and no. Consequently, we recommend zeroing the rifle with the magnifier attached and never removing it from the gun once it is zeroed. The point of impact does not change, but there is a significant shift in the point of impact.

It makes no difference whether you zero your weapon with a hand-held laser boresighter or with live ammunition-you can be confident that the point of impact will not vary as the magnification level of the magnifier is changed.

Do you have to zero a red dot magnifier?

Yes. You must zero the red dot magnifier, and this has nothing to do with the red dot sight you used to zero the magnification in the first place. In order for your magnifier to be effective, there must be a distance (known as co-witness) between its optical axis and the center of the rifle scope.

This distance should be as short as feasible (in most cases, less than 2cm or 1inch). To compensate for the movement in POI at different magnification levels, zeroing is essential-especially if you intend to use it in conjunction with another sighting system such as the EOTech.

Do I have to calculate the correct holdover?

Theoretically, no. It is possible in practice, but it is not recommended, because every time you change the magnification level on a red dot magnifier, accuracy is lost. There are two variables that contribute to this:

For example, EOTech (and other) sights use only 4-5 different intensities of LED lighting in low light circumstances, which is far from optimal.

You must adjust your point of aim for each magnification level, because the red dot is always in the center of the magnifier, regardless of the power level selected.

It is therefore recommended that you utilize only one magnification level after you have zeroed the red dot magnifier for quick acquisition and follow-up shots after you have zeroed it.

Does any Magnifier work with any red dot?

No, You must first ensure that the magnifier is compatible with your red dot sight before proceeding further (i.e., both use the same controls and features).

It is recommended that you get a unit that allows you to control the intensity of both the RDS and the magnifier with a single control. It should also be noted that some models are not designed to withstand high recoil calibers, but others are capable of withstanding heavy machine guns.

How does a magnifier work with a red dot?

It is important to realize that the magnifier itself does not provide any additional targeting capabilities for your weapon. A red dot sight (RDS) is nothing more than a reflex scope with an LED or laser illuminated reticle, and it operates in the same way as a pair of binoculars, except that it increases the view field of your red dot sight (RDS).

You see the same item no matter how far away you aim with RDS; this is referred to as 1X or "real one power." When you place a magnifier behind such a sight, it will function similarly to a 2X or 3X telescope, resulting in either a larger image of your target (magnification) or a broader view field (width of field) (with variable models).

Both of these characteristics, on the other hand, will not make aiming any easier. And keep in mind that a red dot sight is not the same as a telescope, and it has nothing to do with your ability to fire.

Are red dot magnifiers worth it?

It's difficult to provide a succinct response. The use of red dot magnifiers is highly recommended for close-quarters battle (CQB) and mid-range combat with pistols or carbines.

In these situations, most magnifiers will not only extend your field of view, but they will also improve the accuracy of rapid firing. However, they are not suggested for long range shooting, as a red dot with unmagnified views combined with 3X, 4X, or 6X rifle scopes will provide you with greater benefit (or even night vision devices).

However, it should be noted that a red dot sight with magnification has nothing to do with "night vision" equipment, which is an image intensifier used by professional shooters in low-light situations and is not covered by this article. The RDS, when mounted below the reticle, will provide the ability to widen the reticle (and even switch to the red dot) in low light settings.

Keep in mind that this is NOT an active night vision gadget, and it has nothing to do with image intensification either. Red dot magnifiers can be found on numerous airsoft forums under various titles such as "red dot scope" and "3X magnification scope," among others.

However, these are false phrases that only generate confusion among beginners because the actual RDS does not require any additional gadgets for aiming-you just see the same view field regardless of what magnification level your sight is set to (a true 1X sight).

That is why they are referred to as "red dot sights" rather than scopes or optical gunsights. We further claim that they allow us to shoot at distant objects while keeping both eyes open, which is not possible when using a 1X unmagnified sight, as previously stated.

How much is a red dot magnifier?

Depending on the model, red dot magnifiers can be purchased for anywhere from $70 to several hundred dollars. Optical coating (Fully Coated-F/C, Multi Coated-MC, Fully Multi-Coated-FM/C) and construction style (may be "tube" or "offset") all influence the price of lenses.

Units with a fully multi-coated surface are often suggested for use in both low light and bright daylight environments because they provide the greatest amount of light transmission.

It's also important to evaluate if your magnifier allows you to maintain the unmagnified view field (real 1X sight) or if it just allows you to transition between magnified and unmagnified views when using it (magnifiers without Intensifier Tube).

When do we use a red dot magnifier?

As a general rule, a magnifier is employed for close-range rapid-fire shooting and for hitting small targets in low-light situations.

You can also use a magnifier with a red dot sight that does not have variable magnification or a view field that is not enlarged to get either a larger image of your target (magnification) or a wider view field (width of view field) (with variable models).

Both of these characteristics, on the other hand, will not make aiming any easier.
