Shooting targets at long ranges is not an easy task. It becomes even difficult to get a clear view of the target if the lighting conditions are subpar. However, having a long range scope will help make your shooting or hunting expedition simpler and rewarding in any environment and lighting condition.

First, having a long range scope will help you spot your targets with ease, in spite of their size or how far they are. With the right scope, you will also be able to engage fast-moving targets quickly, easily and more accurately.

Criteria for Choosing the Best Long Range AR-15 Scopes

Choosing the best long range AR-15 scopes is not something to do on a whip. Whether you are looking to upgrade your AR-15 scope or you are in the market buying a long range AR-15 scope for the first time, these are some of the important factors you should put into consideration.

With the high magnification power, you will be able to spot the distant targets easily and bring them closer. This will increase your odds of accurate shot placement. Most long range shooting activities will require a scope with at least 10x magnification power, although it can stretch out to 15x or 20x for extreme long distance shooting.

Image Clarity

Image quality is important for optimal accuracy. For a scope to provide maximum image clarity, it should have high-quality glass and proper lens coatings. With so many scopes to choose from, go for models that either have ED or HD glass. Such scopes offer high resolution and color accurate images. To add on that, make sure that you select a scope that has fully coated lenses or fully multi-coated lenses.


When it comes to long range shooting, reticle selection matters a lot. Different long range scope come with different reticle shapes and styles to meet the different needs of users out there. If you are a beginner, make sure that you get a scope whose reticle is simple to use.

You will also have to choose between a reticle placed on the first focal plane or second focal plane. If you can afford, go for a first focal plane reticle scope as they offer more advantages when shooting at long ranges than their second focal plane counterparts.


The other important thing you should consider when looking for the best long range AR-15 scopes is the housing quality. Generally, the better the housing, the more reliable it will be. Scopes made of aircraft-grade aluminum or magnesium alloy are the most sought after for long range shooting with the AR 15. Such scopes are able to stand every kind of abuse they receive. In addition to the quality housing, make sure that you pick a scope that is fully sealed and filled with either nitrogen or argon gas so it will be fully waterproof and fog proof.


If you will be shooting your AR-15 from a bench or on a constant position not far from your vehicle, the weight and size of the scope should not be a big concern. However, if you are going to use the scope primarily for hunting where you will be required to maneuver from one point to the other looking for game, both the size and weight of the scope are of the utmost concern. In such a situation, you should get a scope that is lightweight for ease of carrying and compact in size for convenient packability.
