It'll work just fine. All lowers are the same; except for color differences.

It will work just fine, BUT not all receivers are the same. There are some combos that will not work, for example, with certain Colts.

Please tell me WTH this respose has to do with using a Rock River lower and any current production upper?

Because your initial post was factually incorrect. If you said "all current production lowers are the same" then you would have been right. But you didn't.
