best acog and mount for low applications?

[dvdcrr]

I was wondering for non ar applications where a low mount is desired to get the ACOG as close as possible to the rail, which acog model and mount would be the best.

As far as I know, this is a standard rail mount on my ACOG. I don't see the ACOG getting any closer to the rail.

I've seen another type with a somewhat low ring mount.
