They're not that new; they've been on the Sako site for a few years. I have a Quad in synthetic, and other than a few things that needed correction (new bolt handle, new floorplate.........and the stock needed to be lengthened; yes lengthened), I think it's the best rimfire on the market.
Not that the synthetic parts would break, but at that price it feels wrong to have plastic in those places. There's a guy who is making aluminum bolt shrouds on another post on CGN, and I was going to send him my bolt shroud to see if he could duplicate it in aluminum, but when I took it off I realized that it was such a complicated part that there was a reason why they casted it out of synthetic..........even made on a grand scale they would cost upwards of a couple of hundred dollers.
