The Best AR-15 Scope for Your Needs

As far as guns go, the AR-15 ranks as one of the most popular. It is lightweight and easy to move around. It also shoots semi-automatic, so it is very reliable. Plus, it is very modular, which means people can add different parts to it. There are about 15 million of these rifles in the United States alone.

Shooters love the AR-15 because it is so customizable. Many options are available for customizing it, including handguards, grips, bipods, and rail coverings. However, the most important accessory you can add is a quality optic.

There are a lot of different optics that can be used with an AR-15. But not all of them are scopes. If you’re unsure what kind of optic will help you meet your shooting goals, we can help you figure it out.

As we explore the world of modern optics, you will learn about how to choose the best optic for your needs. By the end, you should understand what is available and how to pick the right one for you.

Quick Picks:  Best AR-15 Scope for Your Needs

Types of AR-15 Optics

There are several different types of optics that can be used with modern sporting rifles. Let’s have a look at the many lenses available to photographers.

Variable Power Scopes

Variable power scopes let you see things close up and far away. This makes it good for when you want to shoot something from a distance or when you want to shoot it close. Variable power scopes are among the most versatile types of scope available for your AR-15.

People who like to shoot for sport choose a variable power scope for their AR-15. This type of scope can be used by hunters, 3 gun competitors, tactical shooters, and casual plinkers.

The downside to this type of optic is that it is bulky and heavy. This is because the lenses and internal structures for variable magnification need more space.

Fixed Power Scopes

Most current fixed power scopes use a glass prism to enlarge the sight picture. This makes them more compact than variable power scopes, which can be a good option if you have a carbine-length A.R. or if your rifle has limited rail space.

A fixed power scope limits the magnification level of your weapon. This can make it difficult to engage close-range targets.

Red Dot and Holographic Sights

Both red dot and holographic sights have a brightly lit reticle that makes it easy to see. They both have a wide field of view, making it easy to find and target fast-moving targets. They are both good choices for close-range shots.

These sights are very easy to use, so they are good for new shooters. They can also be helpful in home defense situations, where someone who is a good shot may not perform as well because of the fear and adrenaline.

These two types of sights use different technology to provide a similar shooting experience.

Holographic sights use lasers and mirrors to put a reticle (a kind of crosshair) over the target. They offer more detailed reticle configurations than regular red dot sights. They are also good for shooters with astigmatism.

Costs associated with holographic technology are high. These optics are more expensive than regular red dots, as a rule of thumb.

A targeting point is projected onto the mirror using light-emitting diodes (LEDs). The red dot is reflected in the shooter’s eye by the mirror. The reticle is typically a simple red dot that the shooter needs to align with their desired target to fire the weapon correctly.

Many astigmatic shooters have difficulty focusing their eyes on a red dot sight. This is because they instead see a blurry or fuzzy red smudge.

Digital Scopes

Digital scopes are high-tech options usually used for shooting in the dark. They use thermal imaging or digital night vision technology to help you see targets in the dark. Many models also offer cutting-edge features like ballistic calculators and recoil-activated video recording.

The Special Competition Reticle (SCR) is found on scopes in the First Focal Plane, and they are effortless to use. They have XT-100 click knobs, so you can make 100 clicks per rotation. The Zero Click Stop will let you return to zero precisely. The mil-based scope has 0.1mil adjustments, and the moa scope has ¼ moa adjustments.

The 34mm tube means adjusting it to shoot further than 1000 yards. But it costs more because you have to use rings that are 34mm wide. The XTR II is a heavy scope, weighing 32.10 ounces, and is 16.31 inches long. It takes a CR2032 battery to power the illumination, but you can see the reticle without the light on. Its minimum focusing range is 50 yards via the stiff side focus that will break in after a short time.

There are many good things about the Burris competition and tactical scope. It has a Forever No Questions Asked Warranty, which is excellent. You should consider getting it if it is under $1000.

What Does an AR-15 Optic Do For You?

Installing an optic on your AR-15 can be helpful because it offers you something that standard sights cannot. They can help you engage man-sized targets at distances up to 500 yards. However, you can still hit far-away targets without using an optic with the right skills and practice.

An optic lets you shoot targets faster, more accurately, and precisely than iron sights. A variable optic gives you the ability to see your target at long distances. You can see and shoot smaller targets out to 500 yards with ease.

The modern magnified scope makes it easier to compensate for windage, elevation differences, and bullet drop.

If you don’t want to shoot very far away or shoot under 200 yards, BUIS (backup iron sights) will work. But a reflex picture will work better. Reflex sights are faster, more precise, and easier to use in low light conditions than BUIS.

Dot sights help you take shots more quickly and easily. They also help you transition between targets more quickly. Additionally, they can be used with night vision devices for better accuracy.

It is always faster and easier to use a reticle than line up BUIS. Reticles are also easier to focus on than standard sights. They can do a lot, and I believe every AR should have a set of iron sights as a backup option. However, modern optics really are the way to go.

An optic can help you hit your target better than iron sights can. However, you’ll still need to have the skills and know-how to use them to hit your target.

Best AR 15 Scopes Buying Guide

1. Magnification

Scopes are often marked with numbers. How large the number of objects will look to you and how big the lens is. The bigger the lens, the lighter it can let in, and the better the image will be.

You need a scope with a magnification of 9x or more for shooting over long distances on open ground. This should be teamed with a lens that lets in a lot of light so you can see clearly over long distances.

Image clarity is more important than magnification in close-quarters tactical settings and shooting at point-blank range. A 1-4 magnification will be good enough for these situations. These scopes meant for close-range encounters are smaller and have a low profile.

2. Shooting Distances

  • Ranges are classified into three broad.
  • Close – up to 150 yards
  • Medium – 150 to 350 yards
  • Long – 350 to 800 yards

3. Reticles

  • Duplex

    There are different types of reticles, which are markings on the eyepiece of a scope. The magnification of the AR-15 affects what kind of reticle you should use. A duplex reticle is familiar and easy to use. It has a cross with thick and thin lines at the intersection location. Some scopes incorporate a duplex reticle for long-range shooting to correctly estimate distances.
  • Mil-Dot

    The duplex reticle is quite similar to the mil-dot reticle. The only difference is that the mil-dot reticle always has markers to help measure distance in both horizontal and vertical planes. Marksmen and hunters who like to shoot long distances prefer the mil-dot reticle.

  • BDC

    The BDC reticle helps you figure out how gravity affects the bullet. For long-distance shooting, you need to aim higher than usual. The BDC reticle tells you how much to adjust your aim based on the shot’s distance. All scopes designed for long-range shooting have a BDC reticle.

    Illuminated reticles are used to help you find your target more easily in lowlight conditions.

4. MOA or MRAD

You must calibrate your scope to get the most out of it. You must know how much an inch of coverage motion equates to a specific distance on the field. Once you know this, you can use the minute of angle equation to figure out distances more accurately. It may be complicated at first, but the benefits are worth it!

The first step is to divide the circle into 360 equal portions (degrees). Each degree can be subdivided further into 60 equal parts called minutes. This becomes very important when you are sighting your new scope. You need extreme accuracy because any error will be multiplied.

The MOA dot in the scope will enlarge to 1-inch at every 100 yards. The knobs on the scope can help you adjust it so that the dot is on target.

5. Objective

The objective lens is the lens on the scope’s outside. The larger the lens, the more light it will let in. This improves the clarity of the image, especially in lowlight situations. Larger lenses are heavier and bulkier, but they provide a broader field of view.

The exit pupil is crucial because it affects how much light gets into your eye. The objective (the size of the lens) divided by the magnification (how much the lens enlarges what you see) tells you how big the exit pupil is. Usually, people have a pupil size of 2-4mm during the day. This rises to 5-9mm at dawn and dusk. So in low light conditions, it is good to have a large exit pupil so that more light gets in.

6. Focal Plane

The etching of a reticle can be in the first or second focal plane. In the first focal plane, it is close to the objective lens. The second focal plane is close to the ocular lens and eyepiece.

When the magnification power of your scope is adjusted, the reticle (or aiming point) becomes magnified along with the image. This means that when you zoom in on something with a mil-dot reticle, the small markers will become enlarged and more accurate over long distances.

The reticle in the second focal plane behaves differently from the reticle in the first. The reticle’s size will stay the same, no matter what magnification you use. People can choose which configuration they want to use based on their needs and preferences.

7. Parallax Adjustment

the scope at a range of 100-110 yards. After looking at the target, move your eyes around and look for any image movement. If you see any difference, then parallax is present.

You can fix this problem by using the adjustment on your scope. If your coverage doesn’t have a separate parallax adjustment, you will need to sight the area again. The disadvantage is that you can’t correct parallax in the field if your scope has it.

8. AR-15 Rifle Types

  • Marker-Based Augmented Reality
  • Markerless Augmented Reality
  • Projection Augmented Reality
  • Superimposition Based Augmented Reality

9. Eye Relief

The distance at which a scope can be comfortably held from the eye is eye relief. This varies with the power of the scope.

If you need more space between the scope and your eye, you can adjust the mounting to get a better view. 3-4 inches is average, but for larger rifles with more recoil, you might want more space.

10. Accuracy and brightness

Some shooters think it’s not worth using if a scope isn’t clear. This is especially evident at sunrise and sunset when the light changes dramatically. The brightness of the scope is also essential.

When hunting for a big game, it is essential to be accurate with your rifle scope. You only get one shot, so make sure it counts!

Cleaning & Maintenance Tips

The most common way to damage a lens is by dropping it. The second most common way is water, dirt not being removed or removed improperly. To clean the lenses, you will need:

  • Lenspen and
  • Spudz microfiber lens cloth

Tips for Servicing and Cleaning

  • Prevention is always better than cure.
  • Cleaning your scope takes only a few minutes.
  • Implement a plan to regularly maintain your scope.
  • Breakage is the most prevalent type of damage.
  • Remove any water or debris from the lens as soon as possible.
  • Use high-quality lens cleaning materials such as lens cloths or brushes.
  • Clean the lens with a cloth before using the brush to clean it.
  • When not in use, always keep the lens cap on to safeguard the lens.


  • Tap the lens with the optic facing down to allow dust to fall off.
  • Consider getting a lens pen, a lens brush, or a soft-bristled brush.
  • Clean the dusting brush of dirt and oil.
  • By softly brushing the lens, debris may fall off.
  • If you’re using a lens pen, allow for a tighter bristle group by retracting the brush to loosen up hard buildup.
  • To remove smears, use the microfiber cloth in a circular motion.


  • Don’t use your shirttails to clean the lens. They’re abrasive, so they’ll scratch the lens.
  • Because your handkerchief may be contaminated, don’t use it.
  • Don’t use your sleeve to wipe off the moisture.
  • Avoid applying spray cleaners directly on the lenses.

Final Thoughts

Almost all modern sporting rifles have a flat top, so you can install an optic. A good optic will make your shooting experience better. But you also need to know how to shoot without one.

No matter how good your AR-15 scope is, it won’t make up for deficits in your shooting skills. If you want to improve your shooting skills, you need to practice. Make sure to go to the range and shoot some lead downrange with your new rifle/optic set-up.

Frequently Asked Questions About Best AR Scope

What scope does the military use on AR 15?

To mention a few, red dot sights are routinely used by the United States’ top military groups. They have previously and currently employed the Aimpoint Comp M2 & M4 EOTech 553 Holographic Sight.

Should You Put a Scope on an A.R.?

It depends on what you will use your gun for. If you only shoot close-ups or use your gun for defending your home, then a red dot is good. It is lighter and faster to use. If you shoot from far away, then a magnified scope is better.

What Red Dot Scope Does the Military Use?

The United States military typically uses the red dot sight is the M668CCO Close Combat Optic. If you utilize an M16 rifle or M4 Carbine weapon, this optic is the most convenient, highest quality, and fastest target speed.

What’s Better Red Dot or Holographic?

Red dots use power-saving LED, and holographic sights require lasers to power their holograms. This is how a couple of red dots have battery power of up to 50,000 hours. Compared with holographic sights that usually offer 500 to 1,000 hours of battery life, red dots are the clear winners.

What Scopes Do SEAL Snipers Use?

The Marine Corps has chosen a scope for their newest sniper rifle. This new riflescope is called the Nightforce Advanced Tactical Riflescope.

Which Is Better, Green or Red Dot Sight?

The main difference between green and red dot sights is personal preference. Some people like green better, and others like red better. Green may be easier to see in daylight than red, but red is easier to see in low light.

Can You Put a Regular Scope on a AR 15?

With the AR 15 placed level in the shooting rest, take the scope mount and put it on top of the upper receiver. Each scope mount has a different torque level, so be careful not to over-tighten it. Third Step – Add the Scope. Once you have the scope mount, secure it in place before attaching the optic to your rifle.

Can You Co-witness a Scope?

When setting up a rifle with fixed iron sights and a scope, red dot, or laser, it is important to ensure it is aligned properly. This is called co-witnessing. When done correctly, the two sets of sights will work together.

Which Is Better, Aimpoint or EOTech?

If you want a lighter optic, Aimpoint is a good choice. EOTech will work better for you if you have astigmatisms in your eyes. Aimpoint has 3X and 6X options when using magnifiers, while EOTech has 3X and 5X options.

What Does MOA Mean in Red Dot Sights?

The size of the red dot on an optic is measured in MOA. This stands for “minutes of angle” and is a unit for measuring angles in a circle. A smaller red dot will cover less of the target than a larger one.

Do Soldiers Use Red Dot Sights?

Aimpoint red dot sights are popular for hunters, sport shooters, military members, and law enforcement officers worldwide. Millions of these sights have been supplied to the United States military since 1997.

What Scope Does the Military Use on AR-15?

Some of the United States’ most elite military units commonly use the Aimpoint and EOTech red dot sights. These sights are used by both past and present members of these units.

What Ar Sights Do the Military Use?

Aimpoint red dot sights are very popular with hunters, sport shooters, military members, and law enforcement officers worldwide. Millions of people trust these sights. They have been used by the United States military for over 20 years.

Should You Put a Scope on an AR?

If you have an AR-15 in your gun collection, like the SAINT, and want to use it for more than just target shooting, adding a rifle scope can be really helpful. Riflescopes can give you more distance when you’re shooting and can also help you get closer shots. If you’re worried that the scope will be too powerful or that it will take away your ability to shoot close-up, don’t be. There are scopes for every need.

Do U.S. Soldiers Still Use Iron Sights?

Yes, iron sights are still used in the military. Even if a soldier has an optic on their rifle, they need to use iron sights as a backup if something happens to the optic.

What Optics Do Army Rangers Use?

The Rangers carry the M4 and use the new SOPMOD 2 package. This includes the EO Tech 553 holographic reflex site, LA-5 infrared laser, foregrip, M3X visible bright light (tactical light), and associated accessories.

Should I Put a Red Dot on My ar15?

It depends on what you are using your gun for. If you are only shooting close-up (between 0-50 yards) or using your weapon for self-defense, go for a red dot sight. It is lighter, faster, and easier to use. But if you are shooting long distances (over 100+ yards), go for a magnified scope.

Should I Get a Red Dot for My AR?

Red dot sights are suitable for shorter-range shooting. This is because they are lighter than scopes and easier to get targets quickly. There is also no ‘tube effect’ like with scopes. This is because people have different eyes, so the relief on scopes changes how people see them.

What Is Red Dot vs. Scope?

Red dot sights are more accurate and quicker than iron sights and magnified scopes. There are different terms for red dot sights. A “sight” optic without magnification, while a “scope” is an optic.

What Does MOA Mean on a Scope?

The Minute of Angle (MOA) is how we measure angles. It is related to the minute hand on a clock, 1/60th of a degree. Even a slight angle can make you miss the target when you are shooting, so it is essential to be precise and use the MOA to get the angle exactly right.

What Is a 3X Scope Good for?

Your 3X and 4X magnifiers can be used for close shooting situations like CQB or in an urban area. Hunters might also use these magnifiers to take down feral hogs or deer when they are under 200 yards away.
