Yet, it’s not on a par with the high-end military models.

Given that the magnifier is equipped with fully coated lenses, you will benefit from reduced glare and more light when using it in low-light conditions.

All of this makes it the best red dot magnifier within its price range. You can adjust it for both elevation and windage with no tools.

Things You Must Know Before Buying a Red Dot Magnifier

Despite the fact that many shooters use red dot sights, a lot of people do not know exactly what to take into consideration when purchasing a magnifier. This is why we want to point at the critical things of the best red dot magnifiers that have a strong influence on the overall shooting experience. That should help you in choosing the most suitable magnifier for your needs.


Since you are in need of a gear that can increase the magnification power of the red dot sight, the first thing to look for is logically magnification.

The vast majority of red dot magnifiers come with 3x zoom. This works fine for the most long-range shooting purposes. However, there are also models offering 5X or 6X fixed magnification. By making the targets extra large, those magnifiers enable you to aim more easily.

Although a better magnification makes them a tempting option, keep in mind that it’s not necessarily the best choice. This is because high-magnification models are prone to stretching the red dot reticles. For that reason, we recommend sticking with 3X magnification, especially if your red dot has a big reticle.

In contrast to scopes with long casings that house lenses which are capable of catching and redirecting the light almost immediately, red dot magnifiers feature a compact design and are fairly small. The smaller size means fewer lenses, which is why these devices redirect less light to light up the reticle.

While this is not an issue when you are using your magnifier in broad daylight, it can be a serious problem when you are shooting in low-light or dark conditions. Don’t be surprised if the reticle is not visible and you can’t acquire a target. That’s why you should go for 3x magnification. It will let you make quite accurate shots in low-light conditions at distances of up to 300 yards.

Mount Type

By switching from a magnifier to a red dot or vice versa, you can quickly alter your aim and thus acquire multiple targets in the blink of an eye. But in order to switch from close quarters to long- and mid-range shooting, you must have an appropriate mount installed on your magnifier.

We advise you to stay away from fixed magnifier mounts because they can be dangerous when shooting at close range. Instead, use flip mounts as they let you rapidly attach and detach your magnifier depending on the situation.

If a magnifier does not have a built-in flip mount, contact the support service or visit the manufacturer website to find out if that model can be used for your particular red dot sight.

Eye Relief

Depending on the rifle caliber and zoom capacity of your magnifier, you’ll likely need a few inches of the eye relief so as to shoot in comfort. Therefore, you should consider eye relief when setting up the magnifier behind your red dot sight.

A too short eye relief will cause eye strain when you’re aiming at targets. Besides, you will probably have problems trying to see out of your magnifier due to the extended stock. To avoid these issues, choose a model that offers a long eye relief as well as a crisp and clean reticle image.


The red dot magnifiers tend to be bulky when installed on the guns. It may take some time to get used to this, but after a while, you will not pay attention to it at all. Nonetheless, it’s a good idea to choose a lightweight model to slightly reduce the load and maneuver your firearm without much effort. Yet, bear in mind that the extremely light models are usually shoddy, so be careful.
