Many of you will probably be reading this and thinking to yourself – what exactly is an ACOG scope, and do I need one?

Maybe you have one already, or you’ve seen an ACOG scope in action, and that’s what has brought you here?

Well, in this article we are going to run through 5 of the Best AR 15 ACOG Scopes that will fit well with AR 15 rifles. The AR 15 style rifle is ideal for combat scenarios, so a combat level scope should be a fitting addition.

However, before we shoot through the review items, let’s explain what makes these scopes unique and their defining characteristics…

What Is An ACOG Scope?

For those of you who don’t know, the ACOG stands for Advanced Combat Optical Gunsight. This basically means its a sight made for combat situations and therefore combat style rifles.

ACOG scopes are the brainchild of Trijicon, a company reputable for all their gun gear and accessories.

How It Started…

The original intentions of Trijicon were to provide a combat style scope for M16 rifles and M4 carbines – which they did. Now, however, they have developed a full range of ACOG scopes and accessories that will fit numerous gun types in a variety of ways.

We’ll obviously be focusing on the best ACOG scopes that will fit and work well on your AR 15 rifle. Additionally, though, we’ll explore which of the scopes are adaptable for use in the target shooting and hunting realms.

Anyhow, with several armed forces and military units around the world that have adopted these scopes as standard issue, there must be some strong reasons why…


If you want a scope that has proven combat capabilities, the ACOG really should be a number one choice. It has been used on countless tours by military personal, and some will even claim to trust their life with this piece of kit.

Strong in the field…

An ACOG scope stands out from the crowd because it is made to be incredibly sturdy and reliable in the field. The scopes are also designed to be very simple yet effective in taking out targets and to provide you with the powerful visuals you need when your life depends on it.

Most ACOG scopes utilize a non-battery powered illuminated reticle for use in both night and day so that the shooter will always have enough light to target effectively. Others, however, use batteries for powerful daytime illumination too.

Acquire targets Bindon style…

In fact, there is a special aiming style called the Bindon Aiming Concept that was specifically made for ACOG scopes. This concept allows the shooter to use both eyes for targeting and acquisitions. The idea is one eye is looking outside the scope, taking on a very wide field of view – which is for spotting targets easily and rapidly.

Your other eye will be looking through the ACOG illuminated reticle and will be able to acquire the target once you’ve lined up your rifle.

The Bindon Aiming Concept is one of the main reasons why many combat specialists are actually drawn to using an ACOG scope over other options.

Rugged and adaptable…

It’s also worth mentioning that ACOG scopes can be made waterproof to just over 10 meters in depth and they can withstand heavy shocks. Plus, they can be mounted in different ways, making them more adaptable for use in the field.

Many designs differ in magnification, size, reticle layout, pricing, and actual power of illumination. But in essence, they are all made to serve the purposes of combat, alongside the powerful weaponry they are mounted onto.

1 Trijicon TA02 ACOG Battery Illuminated LED Scope

First off, we have this Trijicon TA02 ACOG Battery Illuminated LED Scope, which comes in a black finish.


This particular ACOG scope uses one AA battery to power its illuminated LED set-up.

Given that only one battery is needed, it’s quite incredible to know that the battery will potentially power this scope for 12,000 hours. This timeframe can only be attained by using setting 4 on the scope.

There are six available light settings that give you different levels of brightness, so you’ll really have some nice control over your visuals.

Lightweight yet sturdy…

Because this scope is made from 7075-T6 aircraft-aluminum-alloy, you’ll be getting a super strong and lightweight scope that should really last the test of time. The spec on the aluminum-alloy used really makes this scope one of the sturdiest compared to other popular brands on the market.

Rapid targeting…

Another feature with this scope is that you can utilize the Bindon Aiming Concept for targeting and acquisitions. This is a special method designed to find targets and acquire them rapidly with both eyes open. One eye is used for the wider field of view and the other for aiming.

Finally, this scope used a specially designed ranging reticle which can allow for bullet drop compensation up to a distance of 600 meters.

Having a solid scope in the field should really be a must. The casing on this reticle is extremely strong and durable, using 7075-T6 aluminum which is claimed to be almost indestructible.

A reliable scope option…

A major plus point with this ACOG scope is that it utilizes a fixed magnification. With this feature, you have less moving parts than a variable lens, which can be an important factor for longevity, and a lifesaver in combat.
