So here is my question...in a MOUT setting, would the 5.56 be the preferred platform since it is more "shootable" AND the lanes of fire are limited enough to make the extended ranges a moot point?

(And as far as extended ranges are concerned, I realize that you would be able to extend the range, based on the vantage point, but lets assume a city setting where all the buildings are about the same height...or maybe that wouldn't even matter for my question above?)

Follow on question: If the 5.56 "RECCE" is the chosen platform, would the optic remain the same (around 10X on the high side)? Or would a 1-4X be preferred?
