This keyhole with three dots is on my A2 upper just forward of the rear sight windage knob. No other markings on the upper that I can see, just curious.

I have an A2 upper reciever that I purchased this past Spring that was advertised as an FN. It has the same markings as the ones you described. As Troy stated these are from who forged the assembly so it could be finished by any number of the AR makers. I have heard reference from sellers that these markings are showing up on a number of the AR15 makers guns. Mine seems to be of good tooling finish but a little light(black)on the color. Also the sight assembly is gray. Mantra

The A2 sight base and aperature are steel and have a standard parkerizing finish.

The finish on my upper is great, perfect match for my Oly lower, and the A-2 sight base is also gray. My front sight however is cast, not a problem since it doesn't see much abuse.
