Who, other than Sun Devil, makes a flat top upper w/o an FA? I'm not sure if Sun Devil has feed ramps in their non-FA upper.
Assuming that you are looking for a light weight build I would stay from the milled upper like Sun Devil. I would look for a Rock River 9mm upper ( I think that ADCO has had them in stock yesterday).
