What Is an ACOG Scope?

ACOG scopes are among the most popular options for rifles. Frequently used in law enforcement and the military, These scopes have become the standard for reliable performance. The ACOG comes with fixed 4x magnification, a battery-free illuminated reticle, and a completely waterproof design.

Advanced Combat Optical Gunsight (ACOG) refers to a series of sights developed and manufactured by Trijicon. Based in Wixom, Michigan, Trijicon specializes in the manufacturing of optical sights and the ACOG line is their most popular option.

The company started in 1981 as Armson USA. The company was the sole importer and distributor for Armson OEG gunsights in the United States. The company was reorganized and renamed in 1985, two years before developing the first ACOG scope.

The TA01 4×32 ACOG was developed for the US military for use with assault rifles, including the M4 carbine and M16 rifle. The company has since released multiple configurations of ACOG scopes for use with different rifles.

While it was originally developed for the military, ACOG scopes have become a favorite for all types of marksmen. No matter if you are a casual shooter or a hunter, the ACOG offers reliability in the field.

The one limitation is the fixed magnification. The standard ACOG comes with 4x magnification. However, different configurations and clones come with other magnification levels.

Four times magnification is mostly used for close ranges, between 25 yards and 100 yards. You may stretch your range to 400 yards, depending on your skill and environmental conditions.

If your hunting plans require you to shoot at different ranges, then a magnification that is fixed is not ideal. For everyone else, the ACOG is a superb option, especially in low-light settings.

The ACOG scopes come with Picatinny rails for mounting. ACOGs are mostly used on the M16 and M4. Trijicon has also produced these types of scopes for the Beretta AR70/90, HK416, Bushmaster ACR, SIG SG 550, and Enfield L85A2. These rifles all use 5.56 mm cartridges. However, some ACOG scopes work on .233-caliber rifles, such as the AR-15.

Trijicon ACOG 4x32 Riflescope

Trijicon ACOG – What Makes it the Standard?

The Trijicon scopes stand out for a variety of reasons, including dependability and clear optics. The scopes are built for use in rugged environments.

Trijicon manufactured the original ACOG scopes and continues to manufacture a variety of ACOG configurations for the M16, M4, and AR-15. The high price of the scopes has led several other riflescope manufacturers to start producing ACOG clones.

Over 30 years after the company released the TA01 model, Trijicon ACOGs remain the standard for ACOG scopes. One of the best-selling Trijicon ACOGs is the 4×32 Dual Illuminated Horseshoe Dot .223 Ballistic Reticle Trijicon ACOG.

The 4×32 ACOG includes many of the standard features found on most Trijicon ACOGs, including:

  • Battery-free illumination
  • Rugged aircraft-grade aluminum housing
  • Bullet drop compensator reticle
  • Wide field of view

The main feature is the battery-free illumination. Instead of a battery, the illuminated dot is powered by internal phosphor illumination. Tritium contained in the scope slowly decays, which creates light without the need for battery power. The tritium lasts 10 to 15 years, ensuring a long service life for the ACOG scopes.

Eliminating the need for battery components allows Trijicon to use smaller dimensions for the scope. ACOGs are lightweight and relatively compact.

As the military requires a scope that can withstand the recoil from 5.56 rounds and rapid shooting, the Trijicon 4×32 ACOG is durable. It features aluminum-alloy housing and completely fog proof, shockproof, and waterproof design.

This model comes with a horseshoe reticle for bullet drop compensation and ranging. It ranges out to 800 meters, which is further than most shooters will need with an ACOG.

Other highlights include a wide field of view and easy to adjust knurled turrets. The field of view is 36.8 feet at 100 yards. With the 32 mm objective lens and the reticle that’s illuminated, you get a clear view of your shot in most lighting conditions.

Unfortunately, Trijicon ACOG scopes are designed for a limited selection of rifles. They also come with an expensive price tag. Due to these limitations, you may need to consider buying an ACOG clone for your rifle.

ACOG Clones – Are They Any Good?

ACOG clones are scopes that are based on the design of the Trijicon scopes. The best ACOG clone often includes many of the same features at a fraction of the price. However, when it comes to rifle scopes, you tend to get what you pay for.

The first noticeable difference between a true Trijicon model and a clone is the clarity of the optics. The lower price point of the clones may result in lower quality optics compared to expensive Trijicon scopes. This is not a major issue for the average person. Several of the best ACOG clones come from trusted manufacturers and offer decent sharpness in low light settings.

Even with a quality clone, you may notice a difference when focusing on your target. Trijicon has refined its scope over the years to make it easier to shoot with both eyes open. Shooting with two eyes open allows for faster target acquisition and tracking while helping you remain aware of your surroundings. These are important features in a combat situation, but not essential for hunting.

Budget ACOG clones are less likely to include the brightness and clarity needed for shooting with both eyes open. Instead of fiber optic illumination, many knockoffs come with battery-powered illumination and need for example an aa battery. The clones that come with fiber optic illumination still lack the brightness provided by a true Trijicon scope. They do leverage the fiber optic component to improve over many standard LED-based red/green dot sights.

The next difference is the magnification. Trijicon scopes come with magnification that’s fixed. Four times is the most common configuration, but you can find lenses ranging between 1x and 6x fixed power. Some of the best clones provide different power ranges to suit different uses. If a real ACOG does not offer the magnification needed for your typical shooting situation, you may prefer a clone.

The durability is another differentiation between a real Trijicon and even some of the best ACOG clones. Trijicon ACOGs are built to withstand the toughest environments and heavy recoil.

Overall, the best ACOG clones provide a budget option for those that do not want to spend $1,000 or more on a scope. They may lack some of the features that help ACOG scopes stand out, but they save you money.

Who Makes ACOG Scopes?

The original ACOG scopes are made by Trijicon. You can also find a variety of knockoffs featuring similar designs and features. Most of the best clones are made by budget manufacturers, such as wipboten, Ozark Armament, and Monstrum. These companies are known for manufacturing low-cost scopes.

The budget ACOG clones tend to offer decent performance for their price ranges but may not hold up to rugged use and heavy recoil.

Several midrange scope manufacturers also offer their own design of the best ACOG clone, including Sig Sauer and Vortex Optics. Sig Sauer is a German and Swiss manufacturer of firearms and firearms accessories. The company is known for its SIG P210, P220, P230, and P320 pistols. Sig Sauer has over 70 years of manufacturing experience and offers quality products at reasonable prices.

Vortex Optics is an American-owned company. Founded in 1986, Vortex Optics has earned a reputation for manufacturing a wide range of midrange scopes. As with Sig Sauer, Vortex offers reliable scopes at decent prices, bridging the gap between budget scopes and high-end scopes.

What Makes an ACOG Scope So Good?

The military prefers these scopes due to their durability and performance in low light conditions. The scopes are compact and available with thumbscrews for mounting on the carrying handle instead of the Picatinny rail.

These scopes are made to provide superior dependability in the field. It can take a beating and continue to deliver clear optics. With the waterproof design, it can even remain submerged in water up to 10 meters deep without allowing moisture to penetrate the interior. 

With such an optic, you can focus on your target while remaining aware of your environment, making it a great scope for tactical situations. However, the feature that stands out the most is the illuminated reticle.

Many scope manufacturers offer illuminated reticles. Trijicon sights rely on fiber optics to eliminate the need for battery power. The fiber optic and tritium combination are what make the Trijicon optic a one-of-a-kind. ACOGs also adjust the brightness automatically to enhance your ability to lock on your target in the dark.

What ACOG Does the Military Use?

The military still relies on true Trijicon scopes. The company has expanded its line to include 12 different ACOG models. You will not find the military use an ACOG clone!

The TA31 model with 4x magnification and a 32 mm objective lens became the preferred choice for the United States Marine Corps (USMC) and the US Army. The TA31 comes in several variations.

Trijicon developed the TA31RCO (Rifle Combat Optic) for the USMC. There are two variants, including the TA31RCO-M4 and the TA31RCO-A4. The USMC bought over 100,000 TA31RCO scopes in 2003.

The Army also uses the TA31 model. However, a different model was created for the Army. The M150 includes the same features found on the TA31RCO, but with the parallax set to 300 meters instead of 100 meters.

Some Marines may use the newer TA11SDO (Squad Automatic Weapon Day Optic). It is a 3.5x magnification ACOG based on the TA11 series and adopted by the US Marines in 2010. The TA11SDO mounts on the M249 and has a longer eye relief compared to the TA31 ACOG.

What Is the Best ACOG Clone?

Now that you understand the features that help set ACOGs apart from the competition, it’s time to find the best Trijicon ACOG clone. Here are seven suitable options of such clones.

wipboten 4×32 Rifle Scope

The wipboten rifle scope is a low-cost alternative to true ACOG scopes, featuring a BDC reticle with red illumination powered by real fiber optics.
