What Aspects to Consider When Buying the Best AR10 Scopes?

Before investing in a good scope for ar 10, you must be wary of certain features. These will give you a clear idea of what would be the best option based on your needs.

 Shooting Range

The range of an ar10 scope is divided into three sections based on the gradual increase in zoom. While the close-range scopes do come in handy when hunting, we found that the AR 10 is more well-adapted in long and medium-range encounters.

In most cases, the regular iron sight should be enough for close-range shootouts. Fast and small targets like rabbits and squirrels are the ideal targets when you’re looking to test your short-range shooting skills.

When you increase the distance from the target, the difficulty of getting an accurate shot tends to increase. And so, you will need an appropriate scope to aid your shooting process.

If you’re hunting within a 500-yard radius, you should be using a medium-range scope. This is usually a hunter’s favorite zone as they can easily take down larger targets like caribou, moose, or oxen.

For anyone shooting at a distance over 500 yards loves to challenge themselves. Using long-range scopes will aid your precision, but not by much. Your own skills will determine your accuracy when it comes to larger distances like this.

Depending on the distance, the magnification power of these scopes will range from 6x all the way up to 12x!

Take some time out to think and decide on your preferred target size and distance. This will help you invest in a scope that you will use more frequently.

 Multi-Coated Glass

Since scopes are considered quite expensive, you should always invest in one that will last you for ages. Other than just being able to last for long, it should also provide consistent performance.

The best scope for ar-10 will come with a multi-coating that is bound to survive whatever you throw at it. Shooting is an outdoor activity by nature, which will lead to excessive wear and tear on your optics. If it isn’t well-made, you will soon find yourself investing twice the money you initially had.

Multi-coated glass is preferred over others mainly because of its ability to withstand abrasion or scratching. This keeps the glass fresh for clear shots and a clean view even in dusty conditions.

In addition, the multi-layered coating of the glass keeps fogging at bay. Good quality scopes will have a tight seal around the tube, usually purged with nitrogen or argon. This prevents any moisture from seeping in and clouding up the glass from the inside.

 Magnification Power

This is one of the most crucial aspects you need to consider when choosing the best ar 10 scope. To determine the proper magnification power, you need to lay out your usage scenarios first. The distance range you will frequently fire at and the type of targets you will shoot influence your choice in magnification power.

For long-range shooters, a scope that has 8x or above powers of magnification should suffice. It will allow you to accurately aim at your target over a 600 or higher yard radius.

On the contrary, the 8x zoom would be too much for shorter distances as the target will barely fit into the frame. That is when you need a 2x or higher magnification power to get yourself a wider field of view.


Using a scope isn’t just about performance; you need to be comfortable when aiming as well. Remember those round black rings you see when looking through binoculars? The same happens when you use certain scopes that don’t offer eye relief.

Without proper eye-relief, you will be straining your eyes when aiming for long periods. Other than that, the black ring tends to limit your field of view, further reducing accuracy.

When it comes to purchasing ar 10 tactical scopes, eye-relief is very important. High-quality scopes will offer eye relief up to a certain amount, which will enhance focus towards the target.

 Water and Shock Resistance

When you take your AR10 out into the wild for hunting, it is bound to come in contact with bad weather. And so, it needs to be equally resistant to such situations.

Always look for scopes that come with a fog-proof design and are water-resistant. As mentioned before, modern optics have tight nitrogen purged seal around them to prevent any sort of moisture from clouding up your lens.

Furthermore, your desired ar 10 scope should be able to handle the recoil of your rifle. You need to hold the gun steady to control the kickback. The scope you choose needs to be able to withstand the shock to last you for the long haul.

What Magnification Do You Need for the Typical Use of the AR 10 Rifle Scopes?

The thing about ar 10 sights is that they offer a wide range of magnification settings. Your ability to fire accurate rounds will be primarily determined by the distance from your target and the magnification of your scope.

There is no right or wrong when it comes to choosing specific magnification settings. You could require anywhere from 5x to 25x, depending on your range of shooting.

Since the AR 10 is best used as a long-range shooting rifle, you should look into sniper scopes that offer 12x to 25x magnification. But that is only the case when you’re planning to fire at targets over 800 yards. These scopes are specialized for quick aiming and ensure accuracy across a large distance.

Other than the distance itself, the size of the target also matters. If you’re far out and the distance makes your target appear small, then these long-range scopes should work wonders.

If you’re more interested in taking mid-range shots, you will need to invest in a scope that caters to that. There are tons of medium-range scopes for ar10 rifles that will let you shoot targets within a 500-yard radius. They usually have magnification levels ranging from 5x to 12x.

These medium-range scopes are ideal for hunters looking to target big game. If you use a long-range scope within a 500-yard distance, you will barely be able to fit the entire target into your line of vision.

Advantages & Disadvantages of Using a Scope for AR-10 Rifle

When investing in ar10 optics, you need to be aware of the benefits you will derive from it. While being aware of the advantages is essential, you should also be concerned about any drawbacks you might face.

This will allow you to prepare yourself for any setbacks you might experience during your shooting session.


Enhances Precision

The main motive of any scope is to ensure your shots are well directed towards the target. Using a good scope will let you adjust yourself to reticles and further increase your skills as a shooter.

Low-Light Shooting

Imagine if you had to go hunting in the dark; the lack of light will make it harder for you to locate your target for the perfect shot. Using the right scopes with adjustable reticle illumination settings, you can take advantage of the light transmission to see better.


The AR 10 is a high-quality rifle that can shoot across long distances. It would be a waste if you never use it to its fullest. By attaching a long-range scope, you would be able to zoom in on your targets across hundreds of yards to line up the perfect shot without startling them.


Hard to Master

One of the disadvantages of using a scope is that you have to be very patient with it. Shooters often need extensive hours of practice until they can finally learn to use a scope over a range of distances.

Frequently Asked Questions

1. Where do you put the scope on an ar10?

Follow these steps to mount your scope:

  • Align the scope base with the receiver’s mounting holes. Tighten each screw individually for a secure clamp.
  • Now, mount the rings. Next, evenly turn the windage screws found on the base. In the case of a dovetail ring, using a dowel can be helpful.
  • Check that the rings have a secure fit; if not, some light filing may be required. For a tighter fit, rosin or electrical tape is your friend.
  • Ensure proper alignment of the rings to prevent damage to the scope. Alignment rods can come in handy in this step.
  • After positioning your scope, your reticle and eye relief should be adjusted. Make sure your reticle is level, and your field of view is full.
  • Check if any of the horizontal rings’ screws need to be tightened. If so, follow an X pattern for a secure and even tightening.
  • Once the scope is attached, don’t forget to zero it for the highest shooting distance.

2. Is an AR-10 a good hunting rifle?
