Info/Pics wanted on the KAC MRE Rail in use

[p712k]

I am working on a build using a Knights Armament MRE Rail and am looking for any info or pictures of this rail actually in military service. Especially interested in what optics and muzzle devices were used.

For those that dont know what this rail model is it is a KAC FF Rail with a cutout for the FSB, they were the high speed thing about a decade ago.
