What is the Best ACOG Scope?

1There’s no argument that Trijicon produces some of the best scopes around and their ACOG range is extremely popular.

These were designed originally for the military m4 carbine andm16 rifle but thanks to mounting hardware and accessory upgrades there’s now a host of other firearms that can hold an ACOG.

The line has magnification from 1x to 6x powers and all their sights are illuminated at night using phosphorescence.

The scopes are made with some of the best glass but use no batteries thanks to tritium, though there is a battery version for daytime illumination available on some models.

Optional ACOG features you can find include ghost ring iron sights or another secondary sighting system, Picatinny rails, caps and bullet drop compensation.

The Top 3 Best ACOG Scope Reviews

Let us take a look at the three best ACOG scopes that you can seriously consider in the market today!

Trijicon ACOG BR .308 – $XXXX.xx

Acog 3.5 X 35 Scope Dual Illuminated Crosshair .308 Ballistic Reticle

Rated 4.9 out of 5 stars from 22 customers. Click the image for prices and reviews!

Probably the best Scar 17 scope out there the ACOG is popular with the military but on a .308 the bullet drop compensation is null without the ballistic reticule (o be sure to get that model if you choose this).

It’s designed specifically for the .308 and has a battery free reticule that is illuminated with tritium and fiber optics. It does weigh a bit though and it’s 9” long.

Trijicon makes good quality optics and this is definitely one of them.

These have been around for  30 years now and these are the favorite for many when choosing a combat scope.

They’re not that expensive over all, the cost simply relates to how much the optics themselves cost to produce.

  • 5x
  • 35mm lens
  • shockproof, waterproof, fog proof


So durable it’s practically bulletproof these are meant to stand up to the toughest combat environments, It has a red or green reticule (green is more expensive marginally) option and the glass is super clear. The tritium lasts about 14 years before needing replacement. The


The fiber optics can get a bit bright when in full sun, making them difficult to see and cause a bit of a glow halo and the tritium could be brighter since it’s not great in low light. The eye relief is only about 2” which means your face has to be pretty close.

Trijicon TA31F 4×32 ACOG with Dual Illuminated Chevron .223 Ballistic Reticle – $XXXX.xx

Trijicon TA31F 4x32 ACOG with Dual Illuminated Chevron .223 Ballistic Reticle

Rated 4.3 out of 5 stars from 78 customers. Click the image for prices and reviews!

This is a medium range scope that is much slimmer than the .308 version.

It’s very light and much more simple which makes it better for an AR15 set up.

In fact, it only weighs 10.9 oz and is only 5.8” long.

This ACO scope features the added bullet drop compensation which also works as a simple rangefinder.

The 4×32 power allows great versatility and accuracy over longer ranges up to about 800 yards.

This is another tritium scope that’s battery free and has dual illumination with fiber optics for daylight use.

This reticule is deigned for .223 and the chevron design zeros at 100m when using the tip.

The lenses are coated for clarity and to reduce reflection as well as letting in the maximum light.

  • Waterproof
  • BDC
  • Nitrogen anti-fog
  • 7075-t6 aluminum housing


With about 1.5” of eye relief this means you’re going to get a better cheek weld and better view. As a small and lightweight scope this is an accurate piece of equipment that does its job well. The large eye volume helps you acquire targets quickly and gives you a better field of view. Made of aircraft grade aluminum this is also a pretty indestructible scope and it will stand up well to knocks and bumps without needing to be re-calibrated.


Trijicon deals with a lot of “fakes” and this is the most common model. Look for serial numbers, a statement on the side about Tritium, and raised letter forging for the brand on the housing among other features. This is a real issue as these knock off scopes do not perform even close and often don’t work at all. On the actual scope the eye relief is rather poor and it won’t give you a lot of space if that’s important.

Meade Wilderness Spotting Scope 20-60x80 mm

Trijicon TA31RMR ACOG 4×32 Scope – $XXXX.xx

Trijicon TA31RMR ACOG 4x32 Scope

Rated 5.0 out of 5 stars from 30 customers. Click the image for prices and reviews!

This is a great close combat scope that delivers quick precision.

These are designed for the Bindon Aiming Concept and the RMR helps with rapid engagement.

This means you’re also getting two optics which is perfect for home defense.

This uses both Tritium and fiber optics and has a 3.25 MOA dot.

There’s an option for a red dot or green chevron as preference but that’s semantics.

This is incredibly similar to the F, with the only real difference being that the F model is aimed at more military application than simple home defense purposes.

  • 25 MOA
  • 5” eye relief
  • Waterproof, shockproof, nitrogen treated fog proof
  • RMR


This is a pretty standard ACOG and it’s ideal for someone who likes the F or prior military who is comfortable with the F bu perhaps doesn’t want to spend as much. This is slightly cheaper which is the main draw bu essentially it’s the same scope.


The RMR is a bit high which can affect your cheek weld but it’s a minor issue The position needs nose to charging handle position which means you’re not getting much field of view and won’t be ab;e to move far from the scope. If you want a generous eye relief the TA11 or TA33 provides the best of the line and you’ll get better peripheral vision from it.

So what is the best ACOG Scope?

Actually, it’s none of these! All ACOG scopes are pretty good but as an overall favorite the TA33  has to stand out.

The reason for this is that it’s lighter than all but the TA44-C, has the best eye relief of all, an impressive field of view that’s about 3.7 degrees, and better peripheral vision which makes it better for engagement since you can see around the scope.

This is the most versatile ACOG for fast shooting on a light rifle so you can focus on the target and works well in awkward angles.
