Sorry for the bad pics. Here's mine. It's a DPMS in .204 Ruger with a 24" fluted barrel. For a more in-depth analysis read the review I wrote in the Gun Reviews forum.
Wow, there's a can of worms my friend. I have the infamous quad rail AND a bad lever (crazy I know). Anyway, I like the FDE look. If I had the funds I'd go with a Free float hand guard (troy), VLTOR stock and an FDE AFG (I already had the black one). All of the manufacturers you named are excellent... Be ready to spend some money

Noveske N4 Match grade upper and lower.
ARMS front and rear flip up sights
Aimpoint Micro T-1
