5 Best Red Dot Magnifiers- A Complete Detailed Guide


Red Dot Magnifiers are attachments that used with your non-magnifying red dot to lock your target during long range shooting applications. Generally, when you simultaneously use a good quality magnifier with your already existing red dot sight, you are assured of hunting success especially when long range shooting.

When using red dot sights for short and mid-range shooting applications, I would rate the optical performance of red dot sights at a hundred percent. However, I could notice some kind of middling performance with most of my red dot sights when using them for long range shooting applications. Most of the time I could not see my target clearly especially when they are moving at fast speeds. I came to realize that it was because they lack high magnification abilities. To improve their magnification, I have always opted for magnifiers which have made my existing red dot sight more versatile and ideal for long range shooting applications.

In this article, I have compiled a few of the best red dot magnifiers that dominate the optical and hunting market.

What should you consider when purchasing a magnifier for your red dot sight?

Before purchasing the best magnifier for your red dot sight, you would need to evaluate your overall activity needs and look into your personal preferences. Once you have established what exactly you are looking for, you should look into the following features;

Mounting Type

Generally, there are two major ways that you can mount the magnifier for your red dot; either flip or fixed. A flip-to-side magnifier is the most ideal option because of its versatile nature and it allows you to seamlessly swap across the magnification ranges on your magnifier. Fixed mounts, on the other hand, are not as versatile. You would either need to use the 3x magnification range as is or completely remove the magnifier from your red dot sight to shoot up close. Unfortunately, this would take up so much time and tamper with rapid target acquisition.

In this case, when you are looking for a magnifier for hunting and tactical scenarios, you would be impressed by the performance of the flip-to-side magnifiers but if you are heavily invested in competitive shooting, you would rather go for magnifiers with fixed mounts.

Eye Relief

The eye relief determines your eye comfort when you are trying to identify your target.  Generally, red dot sights lack any sort of eye relief and for this reason, it is important for your magnifier to provide you with a decent eye relief. In this case, whatever magnifier you choose for your activity gear would need to have an eye relief of 2.0 – 2.5 inches so that you can comfortably view your target across all magnification ranges.

Construction Quality

Aside from the mounting type and the eye relief, you would need to look into the overall build quality of the magnifier that you are about to purchase. The lens quality is important as it determines whether you would be able to access bright, clear and sharp views even when you are hunting in low light conditions.

Also, you would need ti check whether its internal housing is Nitrogen purged and O-ring sealed. Nitrogen ensures its fog proof performance when you are shooting across dynamic temperatures and the O-ring seals ensure its waterproof performance when you are hunting or shooting in rainy weather.

Field of View

The field of view on any magnifier determines how easy it would be for you to locate fast moving targets across the entire visible spectrum. A wider field of view would be better for all your shooting applications.

Final Thoughts

Red dot sights are ideal for up close and mid-range shooting applications. However, if you would like to hit your long-distance targets with more accuracy and precision, you would want to combine your red dot sight with a magnifier.


Is the Vortex Optics VMX-3T magnifier compatible with a 3X Spitfire?

No, it is not. Unfortunately, prism scopes such as the 3X Spitfire are not compatible with the Vortex VMX-3T magnifier.

Can I use the EOTech HHS-1 G33 magnifier with my Aimpoint PRO red dot sight?

Yes, you can. It works well with any red dot sight as longs as the mount you are suing puts it at the same height as the EOTech magnifier.
