I recently bought an ACOG TA01-NSN for my Rock River M4. It has the standard front sight post & a flattop upper. I want a buis behind the ACOG that will line up with front sight & not hinder eye relief on scope. Which models work in this situation?

Thanks you,
HS

You can't use a magnified optic and iron sights at the same time. You need a rear that will tuck under your ACOG. To use your irons, the ACOG will need to be removed.

Yes, that is what I meant. If I need to pop off the ACOG, then what would be ready to go & line up correctly? I'm guessing all the flip up rear sights allow enough space to have ACOG mounted in front of them?

Thx

ARMS 40L ought to work. It mounts low enough that it should tuck under the eyepiece.

Check out the big bad BUIS faq for some photos.

There are a few I'd recommend before ARMS.

Well, since the thread author's asking that very question, and you seem to be in the position of one who ought to know what'd work, why not offer up some suggestions? Everyone wants to rain on a parade and not pass out umbrellas.

LMT rear does not fit under my TA-31.

Both the ARMS #40 and #40L fit under mine (just barely)

I love my ARMS #38, because you can get the ACOG up and over the front sight, yet have a standard BUIS.

That is another option I was considering. For $40 more & the buis already there. I wasn't sure what other advantages the #38 offered until your post. I have a long face & raising the ACOG eyepiece a tad more might make it even more comfortable. Thanks for the idea. Anyone have a pic of a #38 with ACOG mounted. I'm interested in standard A4 length #38 mount.

Thanks all,
HS
