2. Nightforce Optics Rifle Scopes for AR-15 – For Extreme Long Range

The durability of this product is a bit on the weaker side as it’s made out of plastic, so it might break somewhere down the line when you’re using it, and the screws maybe loosen up after a few shots, so it’s best to strengthen the bond with an adhesive, and it’s no surprise given its price point.

But other than that, it’s quite an okay scope to use. It’s equipped with an MOA reticle with a center dot and 3 other dots to determine the range, which makes it a lot easier to aim. A 65 MOA ring for more versatility in your configurations.

How To Choose The Best AR 15 Rifle Scope?

Rriflescopes, thermal cameras, night vision goggles, long-range scopes, and thermal binoculars are coming up with advanced technologies, well-built construction, unique features, and several functions to deliver the best results. Likewise, ar 15 scopes are equipped with top-notch features and functionings.

AR-15 scopes and optics, in general, are a very complicated piece of equipment. And lucky for the users, selecting one isn’t as complicated as the instructions on how to use one. There are a few factors that need consideration when looking around for an AR-15 scope, and that is to ensure that you get the best out within your budget.


We’ll start with power. When choosing a scope, one thing that you need to take into account is the magnification. If you’re a beginner, you might think that the more magnification a scope has, the better, but if you’re purchasing a scope for hunting, or using it on a moving target, too much magnification might cause a problem. It may be a nuisance when location or trying to zero in on a target.

The higher the magnification, the more impaired your sight is, and the further you see – so keep that in mind. If you’re just going out to a shooting range, then having a long-range magnification is a good thing, and that’s because you have all the time in the world to find your target and align your shot properly.

Some scopes that are available in the market have variable magnification and will allow you to adjust it accordingly to your target, allowing you to cycle through various different magnification settings. This comes in clutch when you’re trying to scout a target and then zoom in more to focus on your target once you find it.


Some people won’t even consider the weight of scope, especially if it’s unattached to the rifle, but those little things add up and may affect the overall feel of your rifle. If you’re used to having a lightweight scope attached to your rifle, then go for a lightweight one. If you suddenly equip a heavier one or used the iron sights, the changes will throw you off and will greatly affect your performance.


An inexperienced shopper or a newbie may not care much about reticles, but if you’re investing quite an amount on a scope, then you should definitely care about it, especially in achieving a great shooting experience.

Reticles have different variants, and different people will prefer different reticles. A dot or a crosshair in a reticle may not matter much how your rifle will perform, but when it comes to the user, it definitely will, depending on your preference and eye conditions.

Some reticles are even equipped with advanced features meant for professionals, and if you become familiar with them, you might become on as well. Such feature is called a bullet drop compensator.

Those little lines or dots indicate the different levels of range. Usually, you use the center dot or the crosshair to locate your target, and once done, you adjust it accordingly with the use of the lines. These lines are best used on targets that are of considerable range, mostly for moving targets – and that’s why it’s imperative that you get the best scope that’ll match your preference if you’re a hunter.

Effective Range

You may have seen the movie about snipers killing a target far away, and shooting a target from a mile away definitely sounds cool, but only if there’s a bullet capable of traveling that far. Since this article is all about AR-15’s, which only fires a .223 or 5.56 NATO round, it’s impossible for that kind of bullet to reach that far.

The maximum effective range of an AR-15 bullet is only 500 meters away for point targets and for area targets, 600 meters which means that buying a scope that has a range of further than 600 meters will be totally unnecessary.

Most experienced hunters or professionals will use their AR-15 rifles to shoot down a target that is more or less than 400 meters away, even less. Make sure that the scope you choose is that within the range of your usual target is.

How AR-15 Scopes Are Better Than Red Dots?

Since we’re talking about short to mid-range optics, why not go for a red dot instead? Usually, a red dot would be better, but there are circumstances where an ar-15 scope would be a better option than red dots.

If you need further details of how to compare different types of scopes for rifle, check this WikiHow guide.


Red dots are great for fast target acquisition, but that’s about it. Its a downside is that the further your target, the more obscured your vision is, and that’s about it. You can’t do anything about it because a red dot isn’t that flexible compared to an ar-15 magnified scope.

While an AR-15 magnified scope, on the other hand, is perfect for short, mid, and long-range shots. You can easily adjust it to your preference, and overall just presents more accuracy, clarity, and precision.

Shooting distance ranges of AR-15

You have to choose the perfect distance range for your rifles according to your needs.

The following ranges based on the .223 ammo or (5.56 NATO)

Close RangeMedium RangeLong Range
< 150 yardsIn between 150 to 400 yards
More than 400 yards

What Magnification range you need for AR-15

Most of the beginners confused here to choose the right magnification for their scopes. They choose too high or too low magnification because they don’t know what the magnification is and why it is used for.

If you’re a beginner in using the scopes, then we recommend reading our perfect review of riflescopes to know more about scopes.

Close Range (<150 yards):

If you have a close-range shooting distance, then you have to choose this level of magnification.

Magnification: 1X

Most of the people use this range for small hunting game or target shooting. 

Medium Range( Between 150 to 400 yards):

If you have a medium-range,then you can choose this level of magnification.

Magnification: Between 5-9X

This range is perfectly suitable for hunting, so most of the hunters use their AR-15 to hunt the coyotes, foxes, and other varmints to protect their homelands.

Long Range(More than 400 yards):

This range is not suitable for hunting because the AR-15 is not built for this, but if you want that, we recommend the long-range magnification.

Magnification: 9X and up

Types of Optics for AR 15

It classified three major types that are, Red dots and reflex sights, Holographic sights or Holo sights and Traditional optics.

Red Dots and Reflex Sights

AR 15 Red Dot Sight&AR 15 Reflex Sight

Red dot sight is a family sight which includes reflex, prism, and holographic sights. Reflex sights are the type of red dot sight. These sights are very small and exposed sights.

It uses a small illuminated dot for aiming the object. It doesn’t have magnification, eye relief. These sights are very fast when compared to the red dots. It helps to improve the shooting speed.

To know the complete history of red dot check this Wiki page.

Holographic Sights

Holographic sights or holo sights are a more complex pattern with unlimited eye relief. Most of the holographic sights are illuminated.

Much like the red dot sight, the holo sights also helps to improve the shooting speed.

AR 15 Holographic Sight

Traditional Optics

All the optics offers many features you can choose as per your needs.

AR 15 Traditional Optics

How to Use This Best AR-15 Scope – For Beginners

Step 1: Mounting and Understanding Your Scope 

Most AR-15 rifle scopes will come with a mounting system or a way to attach it to your rifle. If not, it’s important that you purchase a mounting system that would fit your rifle and your scope. If you’re having any troubles, a gunsmith will help you with the job.

Step 2: Align the Reticle and Adjust Eye-Relief 

A reticle on a scope is the image you see on the lens, which indicates where you’re aiming at, usually a cross or a dot, but there are many variants in the market. Tighten the mounting rings until the reticle is right side up, and once that’s done, adjust the distance of the lens to your eyes accordingly in order for it not to get hit when the rifle recoils.

Step 3: Familiarize Yourself with The Scope
