Factors to Consider When Buying the Best Red Dot Magnifier for AR 15

You can spend between $50 and $1,000 on a magnifier, so you can want to make sure to make most of your hard-earned money. You need a magnifier that will deliver value for the money you spend.

Therefore, the price should not be an obstacle if the magnifier offers reliable performance for your shooting needs.

In this section, we will share some of the important aspects you need to keep in mind when buying the best red dot magnifier for the AR-15 rifle. The main aim of this section is to help you make a well informed purchase.

The following are some of the key elements to look out for in the high-quality red dot magnifier:

Size and Weight

When it comes to magnifiers, please choose a smaller and lighter design. This can help you reduce weight and maintain the balance of the rifle. The increased length will also affect your eye relief.

Eye relief

Eye relief is one of the ways that modern magnifiers are superior to old magnifiers. The two-inch eye distance used to be good. Now you can get an inexpensive magnifier with an eye distance of nearly 3 inches. Getting a magnifier with a longer eye distance is good when all other options are the same.

Short eye relief is more difficult to use and may put your eyebrows at risk of being hit when the gun is back seated. Please note that when comparing magnifiers of the same technical level, extending your eye relief will usually result in a smaller field of view. However, for the red dot sights and magnifiers, a little smaller FOV is not a big problem.


Magnification is the most important aspect when choosing a magnifier. Occasionally, you will look at magnification options, with 3x being the most popular option. This is because 3x is the best choice for most rifle shooters.

For this reason, we recommend 3x, unless you have other special needs.


Please check the construction of all your shortlisted magnification red dot sights. The prices of these accessories range from two to four digits. This means that you may invest a lot of money to make a purchase.

The last thing you want is a fragile model. You need a product that can withstand the wear and tear of shooting activities and reliably serve you for many years.

In this regard, it is always worth checking the warranty of the magnifier.
