Best Scope for AR-10 Buying Guide

When it comes to firearms, having the right accessories can significantly improve performance. This is especially true when it comes to scopes for short to long-range rifles like the ar10 because, although the rifle can aim accurately long-distance, you might not.

Using the right scope will immediately upgrade and boost your performance, helping you hit the target more times than not! The general rule for scopes is that the more expensive they are, the better and more precise.

However, there are plenty of accessible options that are ideal for beginners or for those that don’t want to spend so much money, and the quality doesn’t necessarily drop, you just need to know what features to look out for.

If you’re new to this world, you might struggle with finding a good scope for your ar10, especially with all the options and all of the technical features listed in the product descriptions. Here is a small and simple guide to the main factors to consider when buying a scope for your ar10:


The magnification of your scope is determined by the use you are planning on giving it. What shooting activity are you going to use it with?

If it is mid to long-range hunting, what kind of game are you hunting, and during what time of the day? These are all questions you need to consider as they affect your choice.

The zoom capability of the scope, along with the clarity of the image at higher magnification is a big factor to consider, especially for longer ranges. 

If you are a beginner or want more of an all-rounder option, we recommend you go for a versatile magnification option. 

Focal Planes and Reticles

You can choose between a first or second focal plane when it comes to scopes, and what you go for depends on the use you are wanting to give your ar10 and personal preference.

In the first focal plane, the reticle increases in size as the magnification increases. In a second focal plane, on the other hand, the reticle remains the same despite the changes in magnification. 

As for the reticles, the more variety the better. If you’re planning on hunting in low-light conditions, we recommend you look for illuminated reticles. 

Clarity and Image Quality:

If you can’t see through the scope properly, your aim isn’t going to be as good, that’s pretty obvious, right? That is why you should definitely look out for superior image quality and clarity.

Glass-etched reticles tend to be a lot more superior, so we recommend looking for them if possible.

You should also ensure that the reticles are well-protected against weather conditions, so that image and performance aren’t affected. Make sure the reticle is sealed and nitrogen-filled so that it is fog-proof and water-proof. 

Construction and Durability:

A good scope should be able to last quite a long time while remaining at top operating quality to enhance your performance during continuous use.

It is important that the scope is sturdy and durable, preferably shock-resistant too. However, beware of getting a scope that is too heavy, as it will be less easy to manage and might even hinder your shooting performance in certain situations. 

Frequently Asked Questions

What distance is a 10X scope good for?

The standard 10X scope is, generally speaking, the ideal magnification for a target at medium to long-range.

The distance it is best suited for is 250 to 1000 yards. You should note that when shooting at a lower distance than the one indicated as ideal, the 10X scope is more of a disadvantage, as the range of view is decreased.
