OK ladies, thanks to a couple of jarheads emailing me and pointing me to a Wikipedia article, I can safely conclude that the AR's in the picture are indeed the new 7.62 x 51 NATO highly accurized semi-auto sniper system that is officially adopted by USMC. It is not a 5.56 weapon!!
In any case, I want one!!!!!
Check out his site. You may buy one, if you have the quals.

They have more rifles than you can imagine.
I looked all through that site and didn't find one...
