Top 5 Best Acog Scopes on the Market Reviews:

 1  ​Trijicon ACOG 4 x 32 Scope Dual Illuminated Cheveron Reticle

Trijicon ACOG 4 X 32 Scope Dual Illuminated Chevron .223 Ballistic Reticle, Red

First up, is the Trijicon ACOG 4x32. You should immediately notice that it has an illuminated reticle. This helps you acquire and recognize your targets faster. It works great in a low-light situation. Whether the sun is going up or coming down, you’ll have a reliable scope. After all, most hunting successes do happen in low-light conditions. A lot better than sitting all day and waiting fruitlessly, right? The illumination is battery-free, so you won’t have to carry extra batteries. It has a combination of tritium and fiber optics inside the reticle. You will never struggle to see it.

The housing is made from super durable 7075-T6 aluminum. Essentially, this scope is indestructible. You’ll also be able to acquire your target much faster. You'll love using this scope in a CQB situation.

This scope will work at most distances, but the CQB setting is great. The scope is mostly calibrated for 5.56 NATO AR-15 rifles. It will even work with .223 caliber rifles. Either way, you’ll have a scope that gets the job done. Its accuracy stays the same up to approximately 900 yards. Once again, this scope has the ability to go distances and be reliable in CQB settings. There's a reason it is one of the highest rated ACOG scopes on the market.

The high quality is reflected in the price. People on a budget will likely not be able to afford this one. But it’s worth every single penny. It has a chevron style reticle. That style allows you to precisely aim.

One of the advantages is the picture quality. The image is perhaps the clearest of any ACOG scope on the market. Don’t be shocked if the image isn’t grainy or blurry. You’ll be amazed by what you’ll be able to see. The construction is also super durable and quite solid. You will never have to worry about your zero being thrown off because of recoil. The scope is even shockproof. Nothing will threaten your settings.

One major disadvantage is that the eye relief is quite shallow. More specifically, it’s measured at 1.5 inches. Follow-up shots will be suspect. Another disadvantage is that it needs specific rail systems. It may fit on some Picatinny rails, but not fit some Weaver rails. If you’re a fan of the Picatinny rail, you probably won't have any issues.

If you’re looking for an excellent ACOG scope, the Trijicon is for you. If you can swing the price, it will be the best use of your money.

 2  ​​Trijicon 4x32 Scope Dual Illuminated Crosshairs

Trijicon TA31RMR-G ACOG 4x32 Scope, Dual Illuminated Green Crosshair .223 Ballistic Reticle, 3.25 MOA RMR Sight

Now we’ll be taking a look at the Trijicon 4x32 Scope with dual illuminated crosshairs. The dual crosshairs allow for both daytime and nighttime settings. In other words, you have one reticle that you can use during the day and another for low-light and nighttime hunting. If you’re looking for something that can do it all, try this Trijicon ACOG scope.

Both reticles are green illuminated to give you a great view. Plus, green sticks out better than any other color. No matter the condition of your eyes, the reticle will be bright enough to see without glasses. The high-quality aluminum construction is solid and durable.

This scope will be best used for AR-15 rifles chambered in .223 caliber rounds. You’ll be able to hit your targets from over 800 yards out. This scope is ideal for accurate long range hunting. For example, you can use this on a 6.5 Creedmoor rifle if you’re more of a long range hunter. The Creedmoor is an AR-style rifle that is the standard for long-range shooters. It’s the kind of rifle that is higher-quality than any other long range rifle. ​

Like the Creedmoor, this scope is proven to be much more effective at long range than any other. Yes, we’re talking about the ones that would cost you thousands of dollars. Even this scope is expensive. The money is well spent if you’re looking for something that works for hunting and range shooting. This Trijicon scope can work hard no matter the time. You have something that’s reliable and sharp that can last you a long time. If that’s exactly what you’re looking for, take a closer look at the Trijicon ACOG.

One major advantage is the image quality. It is crystal clear (and perhaps even rivals the other Trijicon scopes). You’ll get a crisp image every time you look through it. The 32mm objective will give you plenty of focus. You will never struggle to quickly acquire your target.

But there are a few disadvatnages. One major disadvantage, of course, is the price. Its cost may not be ideal for those on a budget. Keep in mind that there are some ACOG scopes similarly high in quality but more affordable. This one is expensive but is worth the money.

If you’re looking to turn your AR-style rifle into a long range force, try this ACOG scope from Trijicon. You cannot go wrong no matter the day or time.

 3  ​​​Trijicon ACOG 3.5 x 35 Scope Dual Illuminated Crosshair .308 Ballistic Reticle

Trijicon TA31RMR-G ACOG 4x32 Scope, Dual Illuminated Green Crosshair .223 Ballistic Reticle, 3.25 MOA RMR Sight

Trijicon TA11J-308 ACOG 3.5x35mm Dual Illuminatedx 40mm, Red Crosshair .308 Ballistic Reticle with TA51 Mount, Black

Now let's look at the 3.5x35mm version of the Trijicon ACOG scope. This one, in particular, is specific for .308 caliber rifles. It is probably one of the best on the list in terms of eye relief. The eye relief measures at around 2.5 inches. It will be a little more forgiving than some of the other scopes that we’ve reviewed. Need more eye relief? Then try this Trijicon scope.

The magnification level goes up to 3.5x with a 35mm objective. Your field of view will be a good size. It will allow for quick target acquisition. You’ll get the same accuracy in a CQB setting as well. The reticle is illuminated and doesn't need batteries. You can use this in low-light conditions without worrying about the batteries.

On top of that, this puppy is as indestructible as it gets. The high-quality aluminum housing protects this scope from all kinds of shock, water, fog. The Trijicon ACOG scope will likely be reliable for years or even decades to come.

One major pro that we’ve already mentioned is the eye relief. It is a little less shallow compared to other ACOG scopes. You will get over an inch more in eye relief. This will make target acquisition a little quicker. Plus, you’ll be able to see better without the use of batteries. Long eye relief is quite a convenience when you using an illuminated reticle. Especially when it’s either dawn or dusk.

One con is that the crosshairs to tend to get a little blurry. It's likely not just your eyesight failing. Some have complained that in the dark, the reticle is not as bright as expected. But this could vary from user to user.

If you want an illuminated reticle, then you can’t go wrong with this Trijicon scope. You can hit just about any target up to 1300 yards out. Enjoy this scope if you get it. Because it will stay with you for a long time.

 Trijicon TA02 ACOG Battery Illuminated LED Scope, Black Finish
