It's not a bad deal, but they had a bunch of them sent back for reliability problems.
It seems like the guy is good to go though, so if there's a problem he'll hook you up.
Yesterday I picked up an Imbel FAL at a local shop for that price, but the guy ate the transfer/background fee and threw in 2 extra mags. On the plus side, I got to handle and inspect. On the down side, it doesn't have a FH and it hasn't been refinished. That's to give you an idea of prices going around.
I don't know, seems like a good deal but be prepared to send it back.
MGS has a great reputation, but century receivers do not. they are notorious for being out of spec straight from the factory.
just like with ARs and AKs, youre better off building your own.
