Most Helpful Positive Review Best optic for the AR platform!!!!
This optic is by far the best for the AR-15/M-16 platform. I was issued one in the Marine Corps and used it through 3 tours in Afghanistan. I now own 2 ACOG TA31RCO models, and have this model with the green reticle on the way to me for another rifle! The Bindon Aiming Concept (BAC) makes this optic...

Most Helpful Negative Review Tritium completely dark out of the box
Received the ACOG brand new, and immediately noticed that any glow from the tritium was completely absent even in pitch black settings. Not just 'dim', or 'low light', completely dark. Luckily OpticsPlanet makes it easy to return for free, but still makes me wonder whether this is an issue with Tr...

Great optic period

by Digger, from FL, United States Written on October 13, 2025
If amazing glass and battle proven durability, with no battery and electronics to go bad is your priority, then this scope is worth every penny. An A+ for SHTF dependability. Mount a small reddot to it and it is and will always be all you ever need for a 5.56 platform AR-15 battle rifle.
Pros:
  • Glass, 4x, durable, no battery or electronics
Cons:
  • eye relief a bit short, a bit heavy
Best Used for:
  • Any AR-15 rifle except long range accuracy over 600 meters
Would recommend: Yes

Acog opinions

by Logan Wright, Verified Owner from KY, United States Written on August 10, 2024
I got the ACOG because it’s something h am familiar with and comfortable with. These are some of the best scopes you can get, very durable and you know what you’re getting with it. The only flaw is that it is an outdated scope and expensive. There are options out there that are much cheaper and work just as well. The durability is definitely what gives the acog the advantage over others for me personally.
Pros:
  • Durabilaty
Cons:
  • price
Would recommend: Yes

Trijicon ACoG 4 X32 Scope, Green Chevron.

by Steve, Verified Owner from IA, United States Written on October 31, 2023
Excellent product. The Chevron is bright and sharp in all light conditions. The green color is easy to pick up. I was concerned it I would need the battery backup of some models. I do not use it at night so that has not been a problem.
Would recommend: Yes

Can't get good help!

by Tap em, Verified Owner from OH, United States Written on February 23, 2022
I'm giving this a 3 because the scope has not been tested and proven yet. It could go lower. The optic arrived on time. Upon opening - everything looked fine. Then I opened the Trijicon hard case. The lid fell off in my hand. So, I thought OK. Then I unpacked the scope. Hmmm - where's the scope cover? ---- Broken case. No scope cover. The scope has been mounted and I'm waiting for the weather to see if it is also damaged. Trijicon is great. One phone call and they replaced everything but the scope.
Pros:
  • Trijicon
Cons:
  • damaged on arrival
  • shipping damage
  • used possibly
Best Used for:
  • You gotta ask?
Would recommend: Yes

Nice sight, poor eye relief

by Chris, from TX, United States Written on October 31, 2021
This was my first acog and to be honest, I was disappointed at first. It took some getting used to because I was so used to red dots but I love it now. The 4x31 definitely isn't the best for fast target acquisition up close and if you try it out for the first time indoors with little space you will have a hard time focusing in on the reticle. I actually thought it was broken at first because it didn't know how to use it and the reticle was so blurry. My suggestion to anyone new to this sight would be to mount it before you judge it and get it out doors to look at objects at further distances. Once you learn how to focus your eye sight you will be able to use the sight at closer distances. I only gave it 4 stars because of eye relief and the learning curve of using the optic but overall it is a very nice optic that I have learned to love.
Pros:
  • Solid, very clear, good looking
Cons:
  • eye relief
Best Used for:
  • Mid range to long range
Would recommend: Yes

Finally bought one!!

by Jester, from VA, United States Written on June 13, 2021
Been a long time waiting for this and it was well worth it. Crystal clear glass and easy target acquisition. Spend the money and do it right once. Having gone through numerous other optics I can say this is the last one I will buy for my AR.

I love this ACOG

by Noah, Verified Owner from VA, United States Written on June 11, 2020
The green reticle is bright and no matter the light conditions, target acquisition is fast. The glass is flawless. This was a great choice for me and I have no regrets. It's an ACOG, so it also has a solid reputation and a cool factor.
Would recommend: Yes

ACOG 4x32 Scope Kit

by G, from KS, United States Written on April 24, 2019
This is a great optic but the mount isn’t the best. Still recommend but purchase a better mount. I prefer the green chevron and it can clearly be seen even against a backdrop of trees or other objects.
Pros:
  • Clarity
  • Quality
Cons:
  • Mount
Would recommend: Yes
