If you get us a link, I'm sure we'd be able to let you know for sure whether it's FN made or not. As far as whether their standard rifles are "better" than their stainless Freedom rifles, I think it's more that they're just slightly different, and that's just the barrel. Their Freedom stuff is usually midlength and 416SS, whereas their standard carbines are just that... carbine. I don't know if anyone has found out who makes the 416SS barrels for them, nor have I seen any reviews. I'd say they're probably pretty similar as far as accuracy goes, with the Freedom maybe slightly edging out ahead.
You really can't go wrong with either one, and if you're just plinking, assuming you take care of your rifle(making sure the barrel is dry so it doesn't rust), it's basically aesthetics.
