Things to Consider Before Buying the Best AR-15 Scope

We said it once, and we will say twice that you need to make up your mind and ask yourself some questions before confirming your purchase.

“Why do I need an ar15 scope?”; “What kind of tasks will I be performing”; “Am I going to use it frequently or occasionally?”; “How skilled am I?” “How much magnification is enough for this distinct task?” Once you unravel these questions, you will be sure of what you require and what to buy.  

Now, novice shooters are more likely to buy the wrong scope in exchange for a big fat investment because they don’t know what exactly it is that they want.

That’s why we have curated an in-depth buying guide where you will find what you exactly need to decipher before making a purchase.

The Purpose

First things first, you need to acknowledge that every rifle scope has an individual purpose of service. One might be specialized in distance shooting, while another can be ideal for close-range shooting.

On the other hand, some rifle scopes are incomparable in glass quality and light transmission but don’t work well when making adjustments. So, the point being, they aren’t created the same.

Each of them has its specific standards to suffice. And if you are sensible and lucky enough, you can get one scope that meets various needs, just like the Vortex Optics Strike Eagle, which also happens to be the best choice for today’s review.

So, let’s say you want a scope for close-range shooting with maximum magnification caliber and easy turret adjustments. In this case, your objective is to opt for a rifle scope that is specifically made to cater to these requirements. And if you get other features too then, it’s undoubtedly a surplus.

Shooting Distances for AR-15 Rifle

The second most important thing is to consider various shooting distances, such as how many yards are regarded as close range and how much magnification is needed. So, basically, there are three shooting distances based on how many yards they can reach.

You have a close range which is <150 yards; then you have a medium-range which is 150 – 400 yards; and finally, you got a long range which is 400+ yards.

Now it might drive you to ponder that which one is going to be your shooting distance.

Well, see if you are target shooting or target practicing in addition to hunting small games with your ar-15 rifle, then close-range shooting distance sounds like your thing. The magnification needed for this range is 1-4x caliber.

Check out UTG 3-9X32 1″ BugBuster Scope for your close-range target accession.

Moving on, if you are concerned about saving your homeland from untamable animals like coyotes and foxes, then you will need a scope with 150 to 400 yards of target acquisition capacity.

In other words, a medium-range ar-15 rifle scope is what you need. So that you know, ar-15 rifles are specially made for medium-range shooting.

And they are immensely popular because of their performance in medium shooting distance.

Shooters have a remarkable winning history with their ar-15 rifle scopes. Here the magnification you will need is between 5 – 9x.

Lastly, you have a long-range shooting distance that requires more than 9x magnification.

As we have already said, ar-15 rifles aren’t designed for shooting in 400+ yards, and professionals don’t recommend it either.

Yet if you are optimistic about some long-range target practicing, then just make sure to have enough magnification with the illuminating facility, like our premium pick: Vortex Optics Viper H.S. Second Focal Plane Riflescope.

It is strategically made for long-range shooting. So, depending on the distance range, you should choose the ideal scope for you.

Light Transmission

Your scope comes with an objective lens that allows the light to come in so that you can see the target clearly. Here you will find a label “x” that defines the diameter of the objective lens in millimeters.

Notice the end of the scope where the objective lens is located. It’s usually bigger than the entire scope.

You can call it the heart of the rifle scope that facilitates a sharper, brighter, and clearer field of view.

Mostly when you are shooting in a low-light environment, you will find 50mm objective lenses, which are deemed as one of the most common lens diameters for shooting at long-range distances—the bigger the lens, the better the image.

Now the question is how much light transmission you need for your type of shooting.

If it’s close-range combat, having a 50 mm objective lens can be overkill. In contrast, when you aim at a distant hunting object, you will need a larger lens to let the light penetrate your eyes to brighten the view.

It would help if you stuck to the one that is not less or not too much for the operation you are planning to perform.

Also, larger lenses have some downsides when it comes to maneuvering since it increases the overall weight of the scope. It will cause some discomfort like shoulder strain or wrist ache due to the tension it distributes.

On top of that, a heavy scope requires you to mount it higher than usual since aligning the height proportionate to your cheek weld with proper viewpoint, and peripheral sight is necessary.

And to be honest, that will give you a hard time in terms of obtaining accurate and fair adjustments.

Hence, before determining the ideal lens diameter, you should consider all these underlying facts so that it doesn’t end up causing trouble than benefiting you.

If you want something for your medium-range distance shooting, then use something between 35mm-50mm. It would be enough and maneuverable at the same time.

Finding the Right Reticle

Sure enough, there is a wide range of reticles available, but while choosing the suitable one for your task, you need to see whether it accommodates your rifle or not.

Since we are discussing a semi-automatic gun like the ar-15, the rule of thumb of getting a well-fitted reticle is to stick to the one with brightness adjustability and illumination for all kinds of environments.

Be it a sunny morning or after sunset.

The gradual distance reticle depicts different tick marks for each distance so that you can adjust as desired. It can be red, green, and even black with diverse parameters. Now, let’s have a look at the different types of reticles we often come across while choosing an ar-15 scope.

Duplex Reticle

First, you have one of the most common and primacy type reticles called the “duplex.” See, we will avoid the jibber-jabbers or too much detail and cut to the chase.

A duplex reticle comes in handy when you want to pinpoint a certain target, make adjustments according to the distance and shoot your shot.

Make sure you know that duplex reticles are for stationary targets like a still target in the specific distance which you want to take down with your shooting skill.


Then we have a mil-dot reticle which is perfect when you are rooting for a moving target. You will find a lot of similarities here with the duplex reticle, but in contrast, it has rings, for instance, the vertical or horizontal marks depending on the distance distribution.

What it does is help you with fixating your gun towards the moving target. Then you use your estimation skill to determine the target’s speed, adjust your reticle, make amends if needed, and finally shoot with accuracy.

BDC Reticle

So, basically, BDC refers to Bullet Drop Compensation, and it’s known as an extension of the duplex reticle. However, it’s ideal for long ranges where you can reach up to 600 yards. If you are a tactical shooter or work in the police force, then choosing an ar-15 rifle with a BDC reticle would be the right choice.

First Focal Plane vs. Second Focal Plane

Simply put, the first focal plane reticle changes following different magnification levels, whereas the second focal plane remains the same size regardless of magnification level.

You will notice the image expanding when you increase the magnification in your first focal plane reticle.

On the other hand, the reticle gets narrower or shrinks while the image gets smaller due to the decreased magnification. In contrast, the second focal plane reticle stays where it was positioned, whether you zoom in or zoom out.

Now, if you want to make a quick target acquisition and use the windage and elevation lines at the same time, then the FFP reticle will outshine any other reticles existing.

In contrast, A SFP reticle works wonders when it comes to hunting game animals at the highest magnification setting.

Remember that it will work just fine if you dial up on the turrets on an SFP riflescope. Ensure aiming at the center dot of the reticle despite any magnification you put on.

Parallax Effect

You need to bag a riflescope that comes with zero parallax error. This misalignment of the focal plane gives you an inconsistent field of view. You can fix this if your ar-15 scope rifle comes with parallax adjustment.

For the most part, parallax adjustments often arrive in fixed yardage. We think it works, too, if you are frequently shooting at the exact distance yardage. However, if your scope doesn’t come with this feature, you have to continuously sight your rifle.


Always inspect the overall construction of the scope. The tube should be made of quality materials that can withstand tough situations. Also, choosing a waterproof, fog-proof, and shock-resistant scope material is undoubtedly a sensible decision.

We suggest you scope tubes that are machined from aircraft-grade aluminum with purged nitrogen since it’s proven to secure your scope from any adverse conditions.

Eye Relief and Eyebox

You want a scope that has generous eye relief and a promising eye box where your eyes can sit comfortably and look through the scope effectively. We believe that you already know what’s eye relief stands for.

The distance between your eyes and the scope to have a clear view is deemed as eye relief. The wider the exit pupil, the more amiable it becomes.

The standard eye relief is 3.5 to 4 inches, which is handy for long-range shooting and offers the highest magnification possible.

In contrast, the standard measurement is more than 4.5 inches for long eye relief, and it’s ideal for close-range shooting or where the highest magnification is required.

As for the eye box, you should go for the most forgiving one for placing your eyes with ease and accuracy.

Capped Resettable Turrets

Check if the scope you are willing to buy comes with capped resettable turrets or not because resettable turrets ensure you a great return to zero advantage. And holding the zero after sighting in is a vital factor when you want to dial under the pre-set zero.

Who and Why Own an AR-15 Rifle?

If you are wondering who should own an ar-15 rifle and why then the answer is any civilian can own it for safety purposes. You need to go through all the legal procedures to become an authorized gun owner.

Now, most people always talk about the American civilians, as over 5 million fellow Americans own an ar-15 rifle.

But what about the other countries? Well, you can own an ar-15 rifle regardless of the country you are residing in as long as using it for defense is permitted in your region.

There are countries where ar15 rifles are legal, but the using principles are different than others. Since ar-15 rifles are primarily used in the military, you naturally feel a little intimidated.

But the best part about the military rifle is that it’s examined in the real world, so you don’t have to stress over its reliability and effectiveness. It’s easily adaptive and available for civic use.

You will make a joke out of yourself if you think that having a gun makes you a shady person. Because we have met many people who think only the overseas smugglers keep military-grade combat weapons.

Worst case scenario, gun owners are often deemed as drug dealers or some mentally unstable person.

But trust us when we say this; the fear of invaders, thieves, enemies, and even varmint is real. You would be pointing your gun at the assaulter with one hand and calling 911 with another. Yes! An ar-15 rifle is that flexible and easy to operate!

So, the point being, there are people who own an ar-15 rifle to protect their homeland and valuable assets, while some people use it to hunting game animals.

As the most debugged firearm in military history, this is at the shooters’ disposal, from hunting to home defense purposes.

Principles of Use- AR 15 Scopes

The prime objective of using a scope with your ar-15 rifle is to increase the accuracy range of the weapon.

The best range for an ar-15 rifle is 500 yards; however, it’s around 300 yards in practical aspects.

Now the thing is, your ar-15 rifle scope might be capable of hitting 500 yards if you are too lucky, or it’s a perfect day out. Otherwise, it’s like a dream come true or once in a blue moon case.

But hitting 300 yards won’t be an issue; in fact, making 300 yards shots is quicker than reaching 500 yards. If anything, it works more effectively and guarantees satisfying results.

Shooting for a target that is located within 500 yards of distance should be assigned to high-powered rifles, including heavy ammo and optics.

Another principle is to retain the same speed on the way to the target. The scope is prone to hold the speed rather than drastically lowering it so that you shift from one target to another.

That being the case, people prefer red dot optics with their ar-15 because it moves from one target to another faster with utmost accuracy.

But since the red dot reticle size isn’t precise enough, it cannot shoot past 100 yards. To conclude, if you want to shoot for a 100-yard distance, then equip a red-dot scope for your AR 15.

On the other hand, if you want to reach above 300 or 500 yards, then opt for heavier rifles. The standard niche for an ar-15 rifle scope is between 100-400 yards. Keep these principles in mind before using an ar-15 scope, and you are good to go.

Technical advantage and disadvantage of Having Quality AR 15 Scopes and Optics

Undoubtedly ar-15 scopes and optics are the best when it comes to precision. Not only it enhances your shooting skill, but it also improves your overall experience. You just need to ensure the ideal ar-15 scope for you and the gear to get the most out of it.

Now, since we are talking about the technical advantages and disadvantages of having a quality ar-15 scope and optic, let’s talk about the perks first.

Advantages of AR-15 Scope and Optics

  • Widely versatile in terms of optics and shooting purpose
  • The brightness can be increased
  • Zooming in and out facility
  • Crosshairs and dot colors can be personalized as you desire
  • It offers different intensities which are highly adaptive with an optical range
  • Incomparable accuracy in constant shots despite the range
  • Quick target acquisition speed
  • Incorporates capped resettable turrets for effective return to zero performance
  • Clickable reticle adjustment

  • Affordable price yet the best quality

Disadvantages of AR-15 Scope and Optics

There aren’t any default downside of ar-15 scopes and optics. The issues are fixable for the most part, and the manufacturers offer return policies or lucrative warranty plans. However, sometimes the users receive faulty scopes.

Some of them reported that the scopes were broken when they arrived, or the sights weren’t tuned adequately.

There are also some issues mentioned that the advertisement claimed to provide enough magnification for 100 yards distance shooting, but it barely made it to 100 yards during the practical use.

We believe that these problems can be fixed if you are more cautious about your purchase, as in the “seller’s reputation, the customer’s review, the warranty plans, whether they are responsive to their customers or not, etc.”.

AR-15 Red Dot Sights vs. Scopes

If you are a newbie and are thinking about mounting an optic on your ar-15 rifle, you might debate between red sights and scopes.

The thought of whether to go for a red sight or a magnified scope for your ar-15 is very reasonable since both are widely used and appreciated.

And we agree that both of these are great options as long as you use them for their own unique strength and weaknesses.

Also, it depends on the primary purpose of your rifle. So, without further ado, let’s compare these two optics based on 4 categories: speed, accuracy, weight, and reliability.

CategoriesRed DotScopes
SpeedRed dots are strategically built for speed. At first glance, you will notice that they come without any sort of eye relief which gives your eyes enough leeway to sit anywhere and see clearly through the optic. Also, the reticle design is very straightforward. The bright and visible red dot is sometimes explicitly designed for maximum speed. Moreover, red dots don’t have any magnification and can be beneficial if you want to shoot with both eyes open.Scopes are habitually slower than the red dots. And we believe that two main defining factors contribute to this. First, it requires eye relief, so unless you put your eye at the correct distance away from the scope, you are going to have trouble seeing through the optic. The second factor is the magnification. If you are using a scope with “one power” setting then it’s worth mentioning that they arent truly “one power”. Oftentimes they are 1.1 or something along those lines; just not accurately “one”. So, using them with both eyes open can be tricky for you. And these are two reasons why your scope is a little slower than red dots.
AccuracyIn terms of accuracy red dots lag as it doesn’t come with magnification.Scopes outshines any other optics in terms of accuracy as it comes with different magnification levels. And since accuracy depends on “seeing,” and magnification allows you to see smaller at-distance scopes win this category.
WeightWhen it comes to the weight comparison, generalizing doesn’t really work. Because it depends on the type of optic you are buying, but we would go for the popular opinion which says red dots are lighter and easy to carry.With scopes being attached to your ar-15 rifles, they are mostly heavier than red dot sights. Thus, in comparison to red sights, they are hard to maneuver and cause work fatigue too.
Reliability  Here again, reliability differs from one optic brand to another. Still, for the sake of the comparison, we need to generalize. And that being said, red dots aren’t the most reliable when equipped with ar-15 rifles. Why? Because the reticles here require batteries to run, which can die anytime and stop your operation.The scope’s reticle doesn’t rely on batteries, and even though there are many red dot sights with extreme battery life, you still have the possibility of the battery dying. But here, the reticle is etched into the glass, so even if your scope does use batteries to light up the reticles, it doesn’t matter if they run out because you can still use the optic.

Frequently asked questions (FAQ)

Are AR 15 Scopes Worth It?

Yes, they are worth every penny if you want quick target acquisition with increased accuracy. Through their magnification power, scopes allow you to have a clearer, bigger and sharper field of view than any other optics.

Also, scopes that come with an etched illuminated reticle ensure you have an extended hunting session.

Because you don’t need to stop your task during dawn or dusk time, the illumination brightens the image so that you can see through even in a low-light condition.

Besides, scopes often feature multi-coated objective lenses for maximum light transmission, which is one of the very reasons for installing it on an ar-15 rifle.

Other reasons like the zero holding capacity, brightness control, parallax adjustment, reliability, etc., make ar-15 scopes wholly capable of giving a shot.

Why Your AR-15 Needs an Optic?

Ar-15 rifles are known for their fast action and easy adaptive nature. Using it for close combat and primarily for medium-range target acquisition has proven to be supremely effective than any other semi-auto rifle.

But it works best and serves you the most satisfactory result when attached to an optic. The combination of an ar-15 rifle with a competent scope is deadly.

The magnification, quick adjustment, generous eye relief, zero retainments, and compatibility despite any condition; all are things that advocate the whole concept of needing an optic for your ar-15.

Will I Have to Settle for a Low-End Scope?

No, you don’t. You might have heard it from your friend whenever you are lowering your guard that “Don’t settle for less.” And here we would tell you the same thing.

No matter what your budget is, you can get the best quality scope in that price range. If you wade through all the products from today’s list, you will notice that we have curated them by a low to high price spectrum then in different ranges – because we want you to settle for a high-end scope regardless of the budget and requirement.

What Kind of Scope Goes on an AR-15?

Scopes with zooming capacity with a low-to-maximum magnification of 1x-to-4x power go perfectly on an AR-15, especially if you are supposed to use it for mid-range shooting.

Should I Put a Scope Or Red Dot on My A.R.?

If speed is your only concern, then red dot sights are worth the shot. For improved accuracy and reliability, scopes reign over.

Is an AR-15 Good for Home Defense?

Yes, they are. They are fast and easy to operate; hence in times of emergencies, they come in handy.

However, owning an ar-15 doesn’t mean you can operate it. Ensure taking all the shooting classes or skills required for using a weapon like this.

Because let’s face it, ar-15 rifles are deadly. It can literally kill people. Thus, knowing how to honor the ownership of an AR-15 is necessary.

What Scope Do Navy SEALs Use?

The Navy SEALs use the Aimpoint, Bushnell, vortex, and EOTech red dot sights.

Can an AR-15 Kill a Bear?

It can if you are professional or have skilled eyes, better reflexes, and accurate shooting caliber. Grasping the distance then using your skills to hit the bear multiple times would work.

However, a semi-automatic AR-15 rifle would be barely enough to take down an animal like a bear or cat.

What Optic Should I Put on My AR-15?

It depends on the shooting you are on. There are red dot sights, holographic sights, magnified scopes, etc.

All of them are great as long as you are using them for the right reasons. Find out each of their fortes and use them accordingly with your AR-15 rifle.
