Do you really need to be 1.5 inches away, some have claimed that their 1.9 inch eye relief ACOGs actually were good up to 5 inches. Do a search, there are topics on this issue.

I've got 2 TA31 series ACOGS, and yes, the eye relief is a pain. The rifle I bought the first one for had an A2 stock on it too. That was a pain to use, so I moved it to one with a non-fixed stock. Get used to getting up close and be glad it's only a 5.56/.223 and not a big caliber that kicks.

Yup just learn to scrunch up on it, you should be shooting NTCH anyways. The way you have it mounted is much farther back than how I have mine since I have a Troy BUIS behind it.

However, if you just don't want to than Larue does have a solution. Because we all know if it's something you put your eyes against they'll be something amazing from Larue for it. You loose the ability to use a BUIS but your setup looks almost 3-guns-esque so BUIS probably isn't a big deal for you. Not to mention the Doctor on top.

Oh and if you MUST have BUIS with the above setup do what all the 3-gunners running ACOG's are doing and slap a short range JP sight canted about 45 degrees on there. It works great and is very fast for ranges where the ACOG starts to falter.

make sure your nose is touching the charging handle when you look through the ACOG.

Do you have an ACOG?

TA3x (4x32).... their eye relief is spec @ 1.5".... and yes, you would have to get up close and personal to use this optics.... you use it almost like how you shoot with a carryhandle.... nose touching the charging handle...

It is an amazing piece of optic tho.

PS. try to train yourself on the BAC.... if you don't have a Obj-len cover... try to tape it up with duct tape.... then open both eyes to aim and shoot (1x).... once you are very comfortable with that.... you can open your the duct tape, and now when you are moving quick between objects or if you are close in, in a house... you can aim/shoot with 1x... and if you want to engage far targets, you can aim/shoot with 4x

[TonyM]

Trying to figure out what BAC means? I get the point tho...use the red dot unless it's a longer shot and learn to switch between them in the appropriate situation.

Another question....what is the setup called and how does it work when you see what appears to be 2 scopes in line?

That's not what B.A.C. (Bindon Aiming Concept) is. Checkout the video on this page for a detailed explanation:

The "2 scopes in line" is most likely a red dot (1x, no magnification) with a magnifier behind it.

Good info! I just bought the mount and Im thinking about canting the troy sights like you mentioned.
Is there a reason that NTCH is important?

Consistent cheekweld.

Consistent cheekweld.

NTCH is important for use of irons. You should use a consistent cheekweld between your scope and irons.
