For my last build I used an Aimpoint Comp M2 with a LaRue Tactical Mount. I am very happy with this set up although the LaRue mount brought the sight up a bit higher than I prefered and that took a little getting use to. This time I am seriously considering an ACOG for the Colt 6920 that I am planing to buy.

I have 0 experience with ACOG's so I apologize if these are newbie questions but I have to ask.

1. How do ACOG's compare to my current setup as far as rapid target acqusition?

2. How do ACOG's compare to my current setup as far as field of vision?

3. How are they for night time use?

Thanks!

I'll speak for the models with the BAC, since that's all I can comment on.  Rapid target acquisition is easy with both eyes open - one eye on the scope and the other open and looking around normally.  The beauty of the BAC is that the only thing that your brain recognizes (and therefore, the only thing you see) from the magnified eye is the glowing red chevron which indicates where your gun is pointing.  The best way I can describe what I see when I'm looking through both eyes would be superimposition of the chevron on my normal field of view, very similar to what you would see if you were playing a computer game and it had the little crosshair on your HUD.  This changes when your unmagnified eye and your scope (and magnified eye) focus on the same place - your brain switches almost immediately to your magnified eye, you get the full reticle, and you're seeing through your scope.  It's a bit difficult to explain, but it's a total head-trip when you actually experience it.

Field of vision is going to depend on what magnification you get, and whether or not you get an ACOG with the BAC.  If you've got the BAC, field of vision really isn't that much of an issue anymore because you've got both eyes open and even if you're looking through your scope, you're still aware of what's going on outside of the focused areas.

I can't say I've had much experience with night use on the thing yet, but the chevron is definitely visible as the tritium does a good job.  Of course it's not as bright as daylight, but it gets the job done, and it's a huge weight off your shoulders when you don't need to worry about electronics breaking, batteries failing, or having to carry/pay for batteries in the first place.  Real nice.

ACOG is a great choice.  ACOG with BAC is better

Ive used mine for rabbit hunting at night(TA31F) and it lights up well. With a weaponlight you are good to go and siting targets is cake

Bindon Aiming Concept

ETA - it's great, and took very little getting used to, but I understand that if you're right handed and left eye dominant, it can be difficult, or impossible.

Can anyone else confirm this?  I would love to get an ACOG at some point, but I am left eye dominant, but right handed.  Can't shoot left handed though, since my eye dominance switches to my right (wierd, I know, but I have confirmed it many times)

I have a TA01 mounted on my AR.
Have not had any problems using it. Both eyes open and on target or can use it like a scope, left eye closed for me.
Not sure how it would work with left eye dominant.

Hard to take a good picture but here is a night picture.
11:00pm in town, target is headlight of a car ( 61 yards)
Street light/ house lights are 91 yards away. I had some people come out of the house next door and hurried up and took a picture. Might cause them some concern to see someone in a kneeling position with a rifle of a night time.

Im glad someone posted this question, cuz now I have an Acog question.

Im getting one next month for a 3 gun rig I am currently building.  One thing I cant decide on is this, IF I was to narrow my buy to a TA31DOC or the TA31ECOS, is the ret the same (on the site it just says 223 ret but I know triji has a few different ones...)? I was looking on SWFA.com but I did not see a reticle ref and for some reason I cant get trijicons website to load.  Thanks for any input from those who have em.

This is all very useful info. I think that I will certainlt go with the ACOG. Is there a particular BUIS that you guys would suggest for use with ACOG?

About the same reticle, just a small difference.
The TA31ECOS bullet drop compensation out to 800 meters
The TA31DOC bullet drop compensation out to 600 meters

Trijicon site is working for me.


"Is there a particular BUIS that you guys would suggest for use with ACOG?"

Since my ta01 is mounted on the carry handle I have the stock iron sights in place.
But I did change my iron sights over to trijicon front and rear night sights.

Silentbushmaster:

How do you like that  TA31RCOM4? Can you give me the pros and cons (if there are any) on it? Do you have any experience with TA11 or TA33 and if so how do they compare? Lastly how does it compare to Aimpoint for rapid target acqusition at close ranges?
