I was bidding on one for $2850 with 7 minutes left and some azzhat clicked the "buy now" for $3100.. Argh.. I found another on gunbroker with a buy now of $2900 and just bought it. I've wanted another FDE for a while now and it probably won't be long 'til another azzhat goes on a shooting spree (we've made it at least 5 months now! yay!) and makes the supply disappear (or worse... get's them banned)... So I paid 100-$200 over what I should have but I got the damn gun I've been looking for well over 4 months now and am happy!
As the owner of both: the black is 0.000005% more accurate. In ballistics there is a concept referred to as HAATDAFDE (=Hot Air And Tragic Delusions About FDE) that leads to an unstable air mass and optical illusion when firing an FDE, with a corresponding, and utterly tragic, degradation of accuracy.
