It can be hard to choose a scope for an AR 10. There are so many good choices on the market that it get’s confusing and hard to choose. You may find yourself asking, what are the best AR 10 Rifle Scopes? I’ve done the research, came up with my top picks and now I want to share them with you.
My favorite scope for an AR 10, is the Bushnell Banner Dusk & Dawn Multi-X. This scope gives you really great features at a great price. That is the main reason it is my top pick.
The features are similar to a high end scope and the price is like a mid level scope. Bushnell has made their scopes to have crisp images, nice adjustments and this one has a generous eye relief to protect your eyes.
What To Consider When Buying AR 10 Scope
There are a few things to keep in mind while you are selecting a scope for your Ar 10. I’ve listed a few things here.
AR 10 Scope Durability
One thing to keep in mind as you are choosing your scope is that a .308 AR 10 has some recoil. It has enough recoil that you should look for a scope that is durable enough to withstand it.
Features such as the mechanisms inside the scope that move as you are adjusting, need to be able to withstand the abuse that comes from high caliber shooting.
Most known and established companies manufacture scopes than can take the beating a .308 AR 10 will give. You may want to stay clear of any company that you’ve never heard of or are brand new.
AR 10 Scope Magnification
You will need to consider your shooting distance. Think about what you will be using the scope for over the next several years and use that as your guide.
Since the .308 AR 10 has such an nice range, a 4-12×40 is the most popular scope for this rifle. The 4-12 is the magnification range. This scope has a minimum magnification power of 4x what is seen by the naked eye and a maximum of 12 times. The 40 is the size of the objective lens, in millimeters.
This scope gives you a lot of versatility. It is great for both hunting and target shooting. If you don’t think you will need this much power, the 3-9×40 is also another popular hunting scope magnification range.
Reticle Types for an AR 10 Scope
You will want to look at the different reticles on the market. They each have advantages and disadvantages, depending on how you use it.
Simple, but quick and useful. Duplex reticles works great in low light and will give you the ability to extend your range. Duplex reticle is two crosshairs laid out with four quadrants.
Mil dots let you range targets by using a mil-relation formula.
The ballistic reticle is great for medium range shooting.
This is just a simple sampling of the different types of reticles. You can check out all the different types as you are looking for your favorite scope.
AR 10 Scope Eye Relief
You really want to make sure your scope has enough eye relief, especially for high caliber rifles. You don’t want your rifle to jab you in the eye since it has a fair amount of recoil.
What Does Eye Relief on a Rifle Scope Mean?
Eye relief is the distance between your eye and the scope. There are two categories of scopes when it comes to eye relief. Short eye relief and long eye relief. Both kinds have a different design and use, and have advantages and disadvantages for the user.
Short Eye Relief
1.5 to 5 inches of eye relief, usually considered a regular scope
Most common scopes. Usually found on rifles
Only effective on long guns
Most powerful scopes
Mounted closer to the rear of the rifle
Give a wider field of view
FOV allows more to be seen at a magnified level
Easier to adjust
Clearer picture than long eye relief scopes
Balance the rifle better
Better level of magnification
Long Eye Relief
Generally, anything beyond 6 inches is considered long eye relief
Can be used on handguns
Prefered for hunting revolvers
Limited in magnification power
The most powerful are only around 8x
Better for large caliber rifles with a lot of recoil
Easy access to chamber on bolt action rifles
Certain weapons need a long eye relief just to eject rounds
The difference between a short eye relief scope and a long eye relief scope is pretty major. Short eye relief scopes work better for long range or precision shooting.
Long eye relief scopes are about hitting your target quickly.
AR 10 Scope Budget
I, like most people, enjoy finding the most value I can for my money. I don’t want to buy cheap stuff that will break after a couple of uses, but I don’t want to overspend for something that I may not need. This policy will allow you to get more gear for the same amount of money, which will make you happy.
There are a few companies who have really found how to balance quality and price. I recommend going with those companies.
This is another nice scope that is loaded with features. This thing is durable since it is crafted with solid, one piece design, aircraft grade aluminum alloy. Dead Hold BDC reticle is custom designed to keep guesswork out of holdover and windage correction.
This scope will give you longer range than the 4-12×40 scopes we’ve looked at so far. The lens is oversized and great for high caliber rifles. Of course, just like the other scopes listed, it is waterproof, fogproof and shockproof, and features multi-coated optics.
