Standard style upper (not a MUR)
Has ejection port cover
Flat top
No forward assist
Does have shell deflector
M4 feed ramps, not rifle ramps


Very simple, does such an upper exist?

I don't know of one off the shelf with the ramps; the closest would be the Les Baer with some DIY ramps.

Yep Yep!

The feed ramps are just a few fine round file strokes away. Its really that simple

Yes, they do in fact make that kind of upper, but they arent cheap. The only manufacturer I know of that you can buy direct from is Les Baer. They sell that exact upper.

It's kind of funny that you asked that question since they did an article in "Combat Guns" magazine that I was reading today where the author wanted the exact same thing. He also had the same problem, not a lot of people making them.

I was quite aware of the Les Baer for over a year... but they only came with rifle ramps.  Do they have M4 ramps now?

You could use an RRA 9mm upper receiver, send it to ADCO to have the gas tube hole drilled and the M4 ramps added.  
They already have the clearance cut for the cam pin.
Use it with a standard ejection port door.
