Trijicon ACOG 4×32 Review

As everyone knows, finding a riflescope can be extremely difficult. They are expensive, and the number of features to consider makes it even more confusing.

In this article, we will introduce you to one of the toughest, highest quality riflescopes on the market. While there are many great options, we think that the Trijicon ACOG 4×32 is an excellent choice for most shooters.

Continue reading for a detailed review on the scope based on its best features, and to see our buying recommendations.

About Trijicon

Trijicon is an American company that is headquartered in Michigan. It has been family owned since the late 1980s. Their specialty is a variety of optics designed for weapons, most of which utilized tritium for lighting.

Their ACOG (Advanced Combat Optical Gunsight) series of scopes has gotten to be extremely popular, with over a million products sold. As most shooters are aware, ACOGs are used extensively in the military.

Trijicon’s sights are well respected for their quality and durability. The biggest allure of the ACOG sights is how tough they are. Another drawing feature is the fact that they don’t need batteries. We’ll talk more about that later.

While the ACOG is the most popular, Trijicon makes plenty of different sights, to include pistol night sights, reflex sights, and AccuPoint sights, to name a few.

Trijicon ACOG 4×32

For starters, there are actually quite a few different versions of the 4×32 ACOG. We will talk first about the primary differences between the three major varieties.

The TA01 and its variations are the “normal” ACOG, if you will. We will talk more about reticles later, but these have a very thin reticle.

The TA31 variety have what is called Bindon Aiming Concept (BAC), which allows for you to shoot with both eyes open. Different versions of the TA31 are used in the military.

The TA02 variety add a battery, and have user-selected levels of brightness.

Within these broad varieties, there are even more options, which mostly revolve around the specific reticle used in the scope.

Obviously, the scope has 4x magnification and a 32mm objective diameter, but what other features does it have? While it depends on the exact sight, here’s a general idea of the size and weight of the riflescope.

The scope measures 7.3 inches long and weighs in at 16.2 ounces. The eye relief is 1.5 inches, and the field of view is 36.8 feet at 100 yards. The adjustment per click result in a two inch movement at 100 yards.

Now, let’s talk about the pros and cons of the scopes.


When talking about ACOGs, the first thing that comes to mind is the durability. These scopes are waterproof, fogproof, and shockproof. They are made of an extremely tough aluminum and given a Cerakote finish, which makes the scope nearly indestructible. Literally.

Another excellent feature is that the scopes don’t require a battery (with the exception of the TA02 series). These scopes are illuminated entirely with a fiber optic cable and tritium, which eliminates the need for a battery. This increases the durability, but is also a great feature for survival rifles.

In my experience with ACOGs, I find them to be extremely enjoyable to shoot with. They are accurate, hold their zero, and are very easy to use. There are plenty of things to love about ACOGs, but most people really enjoy shooting with them.

Another pro worth mentioning is the number of reticles available. As previously talked about, there are plenty of different scopes available, and the primary difference between them is the reticle used.

There are horseshoes, basic crosshairs, donuts, triangles, chevrons, and more all available. All reticles also have a bullet drop compensator for increased accuracy at long range.

This variety of reticles allows you to select the exact sight that meets your needs. Some of the reticles will be better for close range, CQB type shooting, and others will be better at a longer distance.

We also loved how there are three different series (TA01, TA31, TA02), and each one meets a specific need.


There really isn’t much that we don’t love about the Trijicon 4×32 ACOG. It is an extremely durable, high quality scope. However, it is extremely expensive. The TA01 scopes are the cheapest of the lot, but they are still very expensively priced.

The only other con of this scope is the eye relief. As we talked about before, the eye relief of this scope is 1.5 inches. This is a very short eye relief, which can make it very difficult to reacquire targets. It also may be tough on your eyes. Definitely try and look down an ACOG before buying one.

Buying Recommendations

Now, we will make some basic recommendations for buying a Trijicon 4×32 ACOG.

If you are looking to do some precision long distance shooting, there are better scopes available to you. Some scopes that are designed for precision shooting can be adjusted much more precisely, and will have better reticles for this purpose.

However, if you are dead set on using an ACOG, the TA01 reticles are the best for accuracy shooting.

For a hunting rifle, the ACOG is an excellent choice, due to its durability.

For tactical purposes, the ACOG is a good option, dependent on the range. If you are expecting to use your rifle at extremely close range (20 yards or closer), like for home defense, you could probably do better than the 4×32 ACOG. The magnification and short eye relief will make it difficult for very close range.

However, if you are using it for tactical shooting at longer distances, there aren’t many scopes available better than the ACOG.

Obviously if you are trying to make a milspec rifle, the ACOG is a great choice, because of how prevalent they are in the military.

Lastly, of the three different varieties, we prefer the TA31 scopes the best. The fact that you are able to shoot these with both eyes open is a huge pro. The military chose these scopes for a reason.


As you can see, there’s a lot to like with these scopes. They are extremely durable, and are overall very high quality.

The best features of the scope are the battery-free operation, and the nearly indestructible performance. Seriously, you won’t be disappointed in how durable these are, and they are backed by a limited lifetime warranty.

While these scopes excel for hunting, tactical shooting, and for a survival rifle, they will excel in any role. If you are willing to pay the high pricetag, this scope will not disappoint.
