1.Trijicon ACOG 6×48 Scope – Best ACOG Overall
Once again, Trijicon has proven it is a forerunner for top-quality optics, with the Trijicon ACOG 6×48 Scope with Dual Illuminated Chevron .308 ballistic reticle. Trijicon developed this ACOG scope with military needs in mind.
Quick target acquisition
We found that the generous eye relief and Bindon Aiming Concept feature allowed for rapid target acquisition during center mass type shooting. You keep both eyes open when using this system.
The 6x magnification was suitable for out to 100 yards. Furthermore, the bullet drop compensating feature on the reticle was accurate for longer shots out to 800 yards, once the gun is sighted to zero.
Self-illuminating Chevron .308 Reticle
It was nice not to worry about needing batteries for this scope. That is because the reticle is self-illuminating. It uses fiber optics in the daylight and tritium in darker lighting situations.
We also liked that the red Chevron reticle was not so bright that it distracted from the field of view but allowed us to see our target in all lighting situations.
Additionally, we loved the adjustment dials used for sighting in the scope. When you pull off the caps, there are knobs instead of small annoying screw/hex heads, making sighting in considerably more straightforward and less time-consuming.
Compact & Lightweight
Other Trijicon ACOG scopes tend to be compact and lightweight. However, the Trijicon ACOG 6×48 Scope with Dual Illuminated Chevron .308 ballistic reticle is not like that. It has a bulkier build. This scope is 9 inches long and has a 2.7″ eye relief.

Buyer’s Guide: What To Look For
As a gun enthusiast that you are, you probably are aware that the AR 15 is one of the most versatile firearm platforms you can get today. One thing users love about this platform is the fact that it allows them to configure their guns per their preferences. As a result, you will find AR 15 weapons ideal for almost any user, including civilians, law enforcement, and military.
Based on your preferences and the intended use of the firearm, the AR 15 allows you to reconfigure several of its components. For instance, you may decide to upgrade the stocks, grips, or even the trigger on your AR 15 gun. However, almost any user of this gun will benefit from upgrading from iron sights to a great set of optics.
Yes, the right optics will enhance your accuracy, speed, and effective range whenever you are using the AR 15. However, you will need to choose from the numerous optics makes and models available today. To do this, here are some of the critical considerations you need to make:
1.The Type of Scope
You must have realized that the various options differ in terms of reticle pattern, magnification power, length, and weight. Despite these differences, these units may be classified into three main types. The choice of the right optic type should be determined by the intended application of the gun, as discussed below:
Telescopic sights, or scopes, are best suited for medium to long-range shots. These units are designed to offer magnification coupled to either dot reticle or crosshair. Based on what you will be using the gun for, you can choose to buy a fixed scope or one with variable power.
With a variable telescopic sight, you will be able to use the on-the-fly zooming to choose your preferred magnification level. Fixed models, on the other hand, only offer a fixed magnification power. If this is your preferred optic type, it is advisable to go for a magnification power of between 3X and 6X.
These are the commonest upgrades from iron sights in AR firearms today. Their preference by a considerable number of users today may be attributed to the fact that they are comparatively affordable. In their functioning, reflex sights project an illuminated red dot reticle on the FOV.
As such, these products are non-magnifying. If you are shopping for a reflex sight for your gun, you will need to consider the reticle size, objective size, battery life, length, and weight of the product. Regardless of the case, you will find these optics compact and relatively easy to integrate into your rifle.
In their functioning, holographic optics may be compared to reflex sights. However, holographic sights apply a different projection system in creating the reticle. Rather than using LED, these units rely on a laser diode to achieve this. By so doing, the reticle is superimposed to the viewing window of the sight.
Holographic sights do not require additional optical components for them to work, which makes them low profile and lightweight.
Once you have decided on the right type of optics you would like to have; you need to choose the right optical power. The correct optical power will be dependent on the distance you’re shooting. For instance, a person who will be shooting targets that are more than 500 yards away will need a more powerful sight than one who will be shooting at shorter distances.
Again, the optical power you go for should be in line with the capabilities of your firearm. For instance, using a 12X magnification scope on a rifle with an effective range of 500 yards will be of no help.
Different manufacturers of AR sights use different reticle styles in their products. Therefore, you will need to find out which of the reticle types works best for you. Each of the reticle types available today has its unique set of benefits and downsides. When shopping for the best AR 15 optics, here are some reticle types you should consider:
The dot reticle is one of the most straightforward reticle designs you can buy today. These reticles feature a single dot precisely at the center of the scope. If you are using your rifle for close-range shooting, you should consider buying a red dot reticle. Scopes with a dot reticle will also come handy in more tactical shooting situations.
Bullet Drop Compensation (BDC)
As opposed to Red dots, BDC reticles allow you to adjust aim with ease and faster, based on your rough estimation of the shooting distance. To achieve this, you only need to aim sown or up. Typically, such products adjust in 100 yard or meter increments. Most of the products within this category are availed as circles, lines, or dots.
Eye relief is another aspect you need to be very keen about when choosing the right scope for your AR 15 firearm. In this regard, you need to choose between the two eye relief options available today; the long eye relief and short eye relief. Most of the short eye relief scopes available today range between 1 and 5.5 inches.
Scopes with a short relief are considered to be best suited for long-range shooting. In such a case, the short eye relief of the scope will give you a relatively large field of view. This, in turn, will provide you with a clear and more concise vision at a higher magnification than you would get from a long eye relief scope.
Optics with a short eye reliefs offer some of the highest levels of magnification available today. Some of these products are also equipped with BDC reticles, which make them an excellent choice for long-range shooters.
The long eye relief sights, on the other hand, are best suited for short-barreled firearms. These are the sights that are longer than 6 inches. While such scopes will give you a narrower field of view, they are recommended for guns that generate a large amount of recoil. With such considerations in mind, you will find the short eye relief sights better suited as rifle scopes.
5. Illuminated or non-illuminated?
Illumination is another thing you should worry about when shopping for the right ACOG optics. So, when will you be using your gun; during the day or night? If you will be using the scope under low light conditions or at night, it is advisable to go for the scopes with illumination capabilities.
If you think that you will not need to shoot under low light conditions, you may go for the models that are not illuminated. However, some models allow you to turn the illumination on or off. Such models are considered to be more versatile as they may be used under different light conditions.
Regardless of your intended application, we hope this guide will help you choose the best ACOG Scope.
