If you have ever seen a soldier or law enforcement officers tactical weapon, chances are you saw an ACOG scope. If you look around at civilian tactical weapons chances are you saw an ACOG clone.
The ACOG (Advanced Combat Optical Gunsight) were designed and built with the purpose of a scope that increased hit potential in the lowest of light settings. The ACOG clone is a financial easier decision to make, and there are still some good performing ACOG style scopes on the market.
In this scope review article, we will take a look at the best ACOG clones that are affordable but will still perform well in the field and discuss the features that make them worth your time and money.
What is an ACOG Scope and ACOG Clone?
These scopes were designed and made popular by the optics company Trijicon.
These are mostly fixed scopes although you will sometimes come across variable power models. ACOG are extremely compact scopes designed to function in bright to low/no light conditions. They also utilize a Bindon Aiming Concept which allows a both eyes open aiming concept where you can maintain a full field of view while utilizing the scope optics.
The real deal Trijicon ACOG scopes utilize an illuminated reticle that is powered by a phosphor system. This involves the radioactive decay of tritium which offers incredible lasting power (tritium has a half-life of 10-15 years). During the day, these scopes utilize a fiber optic light pipe that captures and funnels the natural sunlight for reticle illumination and help match the brightness of in the scope with surrounding light.
If you look at a Trijicon ACOG replica, the illuminating power usually comes from a battery source. Your ability to use a both eyes open aiming concept is also limited with a Trijicon ACOG clone.
There are hundreds of Trijicon ACOG clones that are on the market. Some are completely worthless although, as we will see, there are several ACOG alternatives worth looking at and considering for your ACOG scope.
You might be wondering why you would even bother with a Trijicon clone when the name brand models obviously offer superior body construction and technology.
Well, the reason is an actual Trijicon ACOG scope is going close to a grand for the cheapest model. If you want the best, you better be ready to drop close to 3 grand.
That’s a steep price for most tactical weapon users, especially for those not having to take their weapon into the rigors of combat. Because of this, you might be better served looking at a replica ACOG, and our next section is a short buying guide for what components and features to look for in an ACOG clone.
ACOG Replica Buyers Guide
- Material: ACOG scopes, regardless of Trijicon or some ACOG replica, are designed to be compact and rugged. If you are mounting an ACOG scope on any tactical weapon where the chance of the scope getting knocked around is possible you need a material that is going to stand up to the abuse- including weather abuse- while remaining relatively lightweight. Aircraft grade aluminum alloy or magnesium alloy are the only materials you should ever consider your ACOG clone to be built from.
- Magnification: Most ACOG clones are fixed magnification given their intended role as an all lighting environment combat scope. The magnification level on most ACOG clones is 1X. There are several models out there that have higher power magnification, but it hardly ever goes beyond 5X. What you will want to purchase all depends on the situations you think you and your firearm will find yourself in. If shooting is going to be up close and personal, a 1X is best to give you a wide field of view. If medium to longer range shots are going to be the majority of the shots taken, you will probably be interested in higher magnification ACOG.
- Brightness/Battery Life: ACOG replicas are not going to be using tritium as their power use to adjust brightness levels. Their power source is usually supplied by some form of a lithium battery. It’s a good thing if you want to save money. Just be aware of the manufacturer’s listed battery life. Most clones worth buying have a battery life between 100-500 hours when managed properly. Battery life is extremely important as the illuminated reticle is one of the most important features of the ACOG. If the clone does not have a reticle with a range of brightness settings that lasts for a reasonable amount of time they are not worth buying.
- Rail Compatibility: There are several different rail styles that are used on rifles, shotgun, and handguns. Some of these scopes come with integrated bases for mounting, or you may have to shell out some extra cash for a base not offered with the scope. Be sure that the ACOG knock off you are looking to purchase will mount to the type of railing on your weapon.
- Price: As we have mentioned, these are ACOG knockoffs, and you shouldn’t be dropping more than $500 on any ACOG other than the real deal scope with the Trijicon label. If you’re paying more than that for a clone, you might as well splurge and get the real thing.
The 5 Best ACOG Clones And Alternatives
In the following section we will review a few great options and let you know what in particular makes them a good buy.
This ACOG replica is a 1X magnification optic that was designed for incredibly fast target acquisition in the field. You have the ability to pick and to switch between a 3 MOA red or green illuminated T-dot reticle.
This scope features five different brightness settings for effective use in any lighting condition. This scope is battery powered with a high battery life with proper and responsible power usage. Obviously, if you leave it on high power settings at all times, you’re going to have to change out the battery a lot more often.
The Bushnell AR also has an integrated rail mount for quick and easy installation to any weaver style railing. The base provides a secure and durable locking system that keeps the scope zeroed and on target throughout its use.
It utilizes a 32mm objective lens that has been amber coated for high contrast visual ability as well as excellent light transmission and quality sighting. This contrast is extremely important in low light environments where colors and outlines begin to blend.
This Bushnell model features a useful zoom dot option that allows the reticle to zoom in from 1MOA to 10MOA for long to close quarter shooting accuracy.
The scope housing is waterproof, fogproof, and shockproof. All three are characteristics needed in a workhorse ACOG scope.
The scope is 6.75″ in overall length and has a weight of 15.6oz, which is a little on the heavy end, but not enough to throw off the balance of your rifle.
The FOV (field of view) is rated at 44ft at 100 yards. This is a fantastic FOV for a scope designed for fast target acquisition.
- Excellent brightness adjustment settings
- Integrated rail mounting base
- Excellent lens technology
- Zoom dot option
- A bit pricier than other models
- Little heavy
- 1 x Megapixel
- Red/Green t-dot

The overall weight of the Sightmark SM26021 is just 10.3 ounces, making it one of the more lightweight red dot sights on the market. Despite this fact, it’s also built out of 6061-T6 aluminum with additional rubber reinforcement to help with shock should the sight be dropped. While there are more durable red dot sights on the market, that’s still not at all bad, and it will be suitable if you’re going to be putting your red dot sight through poor and adverse conditions.
Furthermore, the lenses of the Sightmark come with a scratch resistant coating. This is a major plus, because scratches on the coating of any red dot sight can dramatically throw off your aim. Furthermore, the interior of this red dot sight is purged of all nitrogen and is also fully fog proof, which is another major benefit.
The Sightmark is also designed to be attached to a Picatinny rail system, which is one of the most common rail systems in existence and is commonly found on many modern day tactical rifles such as the AR-15.
The main plus to the Sightmark SM26021 Wolverine Red Dot Sight is the 4 MOA red dot reticle it comes with in the twenty three millimeter objective lens. The adjustable digital switch on the side also makes it easy for you to adjust the brightness controls.
Power consumption of the Sightmark is also designed to be very low, which extends the overall battery life greatly. Speaking of the battery, the SM26021 utilizes a single AA battery. This is another plus because not only are AA batteries very cheap, they are also very common and can be found just about anywhere. This stands in stark contrast to many other red dot sights that only use proprietary batteries that are both expensive and difficult to find.
The waterproof rating of the Sightmark SM26021 is set at IP67, meaning that it can resist water when submerged up to a maximum of three feet. Finally, this red dot sight can also function in temperatures from negative twenty two to one hundred and twenty two degrees Fahrenheit.
Overall, the Sightmark Wolverine CSR Red Dot Sight is a great sight for any AR-15 rifle, in addition to other shorter barreled rifles and even shotguns. It’s a compact and lightweight and yet high quality red dot site that offers you a good overall value for the money.
