Most tactical shooters employ various red dot technology on their tactical firearms. For the most part, these sights simply function as iron sights and do not provide any form of magnification. The red dot magnifier allows the shooter to add magnification to his red dot sights and gives the versatility of more accurate long range shooting.

In this article, we will take a look at some of the key aspects of the best red dot magnifiers that set them above other products. We will also discuss some of the pros and cons of mounting a magnifier with your red dot sights. Finally, we will take a look at four models that impress us with their performance and discuss why you should seriously consider using them on your tactical firearms.

Breakdown of the Red Dot Magnifier

As we stated in the introduction, the function of scope magnifiers is to provide magnification to a sight system that functions as an improved iron sight with a true 1X sighting. Most tactical rifles are accurate up to distances much greater than can be achieved simply using a non-magnifying red dot sight and scope magnifiers give you the ability to fully utilize the rifles range.
Not only do they provide the ability for long range shooting but they are also designed to allow you to quickly switch between close range combat orientations to long range marksman settings.
Not all red dot sight magnifiers are equal, and we want to list some key components that go into the best red dot magnifiers.

  • Durability: Tactical weaponry goes through some pretty rigorous shooting exercise and are usually exposed to less than ideal weather conditions. Like any piece of equipment on these firearms, the magnifier scope must be able to perform in these conditions as well as it does right out of the box on the range. Magnifiers should be of a compact design to be able to fit on the rail system at the proper position behind the red dot sight while maintaining the correct position for comfortable shooting position.
  • Magnification Power: It’s important to fully understand the purpose of a red dot magnifier. This red dot/ magnifier combo is not meant to replace a variable scope by any means. Most magnifiers are fixed and are generally in the 2-3X magnification range giving you more accurate shooting at distances of 200-300 yards.
    There have been some improvements in red dot magnifiers technology, and some variable red dot sights have come on to the market. There are pros and cons to the variable magnifier scope, and we will cover these in the Lucid magnifier review.
  • Flip Mounts: When using a scope magnifier, it is critical that it is mounted to your firearm with a flip mount. In true tactical situations, having a red dot with magnifier on a fixed mount can lead to serious problems when facing targets at close range. You will have a horrible field of view and picking up targets quickly becomes extremely difficult.
    To remedy this, magnifiers should be used with a flip mount system that allows you to quickly move the magnifier out of the line of sight and allow you to utilize the red dot. The following products that we will discuss may or may not come with a flip mount, so it is important that you keep this in mind when preparing to mount your AR 15 magnifiers.
  • Eye Relief: Like with any scope, you should be highly conscious of the eye relief provided by magnifiers. When using high caliber rifles, you need a generous eye relief of several inches for comfortable shooting. When mounting your magnifier to your rifles rail system is also important that the magnifier is mounted so that you have a clear image through the red dot glass while still maintaining the proper distance to keep a clear image of the field.

This is a tight, compact scope that is water, fog, and shockproof and can withstand any tactical situation you might find yourself in. It is also lightweight weighing only a little over 7oz. It has a very generous eye relief of 4″ on the lower magnification settings, but you need to be aware of the shorter eye relief at higher magnification settings when mounting this magnifier on the rail.
The ocular focus ring is easy to use and will not slide through normal magnifier use once the image has been focused. The lenses on this scope are fully multicoated to giving you excellent light transmission for the compactness of the magnifier.

If you are in high light environments, it might not be too noticeable, but in low light settings, the higher magnifications are difficult to use.
