I just bought this new upper, it is a RRA midlength, with a DD rifle rail installed.
Taking a close look at it while comparing it to my other rock river, I found that it has this stamp/print mark on it:

whereas my other rock river has nothing there.
Also, when looking at the feed ramps(milled into the upper, the midlength looks like they were dremeled, whereas my original looks like they were cnc cut.
