Red dot for ACOG

[frigzy]

Hi Everyone,

I decided to get a 4x ACOG as a main optic for an all-around ar-15 riffle. I’m going to add a 45 degree offset red dot for the close range encounters (which I hope will only happen during a training class). 2 questions:
1. My ACOG has green illumination. Should I get a green-illuminated red dot (green dot?) as well? Does it matter?
2. I’m looking at Trijicon RMR or Eotech. What would be a good match? Other brands/models are also being considered.

Thanks!

1) It shouldn't matter as long as your eyes can pick up the dot quickly.

2) What do you mean by Eotech? They don't make micro red dots AFAIK. You can go with RMR and experiment with mounting on the ACOG or mounting on an offset mount and see what your eyes (left v. right) prefer.

Look up Bindon Aiming Concept. It works for some people.

Yes, if you learn to use a prism scope like an Acog properly, you might not need an offset sight. It's harder to learn if you rely on the red dot as a crutch

In my experience with using ACOG's for a lot of years I do not need a red dot du jour for close targets. That's inside 35yds for me.

Just remember the POA is higher than POI up close. 2 to 3 finger widths.

This is what I run on several guns.. the placement is perfect and out of the way.. and it's adjustable.

You can run a holosun RMR or a Trijicon if you're Rockafeller.. lol -- I would HIGHLY recommend the Holosun stuff.. better features, better price.. great torture test reviews.. up side to others is "made in USA" which is a consideration.

I have an ACOG and it's harder for me closer than 50 yards.. they also start to stuck in low light.

Canting over to the RMR is so fast and I don't even have to break cheek weld.. only adds a couple of ounces. At the very least it's a back up sight.

I have an EoTech RMR red dot on my PS90... then again, maybe it was a prototype..

[Steve1968LS2]

Here is that EoTech red dot.. I got when working for Recoil.. did they ever go to market with it?



But you will want to go with Trijicon or Holosun since there are a billion mounts for them

Thank you guys for the input - really appreciate this!

I though EoTech is making compact red-dots similar to RMR. Please forgive my ignorance - I'm at the very beginning of my rifle & gear endeavor.

Look up Bindon Aiming Concept. It works for some people.

I read about the BAC. Never had an opportunity to try it. Many people on internet, including Garand Thumb are claiming that even using BAC, ACOG will never be as quick as a red dot at close ranges. That's why I started researching on offset red dots.

You can run a holosun RMR or a Trijicon if you're Rockafeller.. lol

I'm not Rockafeller by any stretch. However, I want all my gear to be absolutely rock-solid and high quality (hoping that it will compensate for low quality of the operator lol). I also like to support US manufacturers every time I can. Thank you for the information - I will do a research on Holosun. The EoTech on your picture looks absolutely gorgeous.

I wish I could go to a gun shop and try all those things out in different combinations. Unfortunately, that doesn't seem to be an option during this ongoing craziness. I probably picked the worst possible time for gear shopping

Wasn't EoTech part of some parent company at the time? I'm not sure, but it kinda looks like something that was offered by Insight so maybe the project was moved from EoTech to the Insight brand.

What dot size would be appropriate for the task? I mean, how many MOA? I really have no reference in this matter and swimming blind

[frigzy]

I ended up ordering a Trijicon RMR Type 2 with 3.25 MOA dot. Could someone please suggest a good picantiny offset mount to run it with an ACOG on AR-15 ?

[Rather Civilianized]

The MOA dot size is a personal preference. As you go up in MOA size, you gain faster target acquisition but lower accuracy because the dot covers more of the target.
As for the picatinny offset mount, Steve1968LS2 mentioned Arisaka. There's a height offset to prevent the RDS from being too low.
My personal preference is to mount my RDS above my scope, but to each their own.

I use the Trijicon offset RMR mount. It works great but it's quite expensive.
