FN owns both the desings and such for the Winchester firearms as well as Browning. as mentioned above, simply making the actiona dn sticking the Winchester rollmarkings on them doesn't make them the same thing as before. Could be as good, better or worse. I do NOT see how they'll be worth the prices they are getting as a MSRP. they'll sell for less of course but even then there's other makes/models I'd go for before one of these.
As for them being made here in the States, remember it was the greed of American union workers that killed them before.
