While they are supposed to start assembling them in Portugal, I've not seen any put together there yet. Not a huge deal either way.
Out of the box they are probably the best USA made rifle right now, but there are a few minor issues I would change. The FN guns have one of the better feeling triggers made, but I prefer the rugged simplicity of the older design. It was not as smooth and crisp out of the box, but could be worked over to be as good as anything else. Only the Ruger trigger is as rugged and dependable as the old style. So far the new design is proving to work, I just trust the older style more. That is the only real design change from older guns.
Some of the newer guns have wood stocks that are not quite as well finished as on older guns. Others are just fine so the problem is inconsistent. There are some subtle differences in shape and feel. At a glance it is almost impossible to notice, but hold 2 side by side and the differences are there. I've read, but cannot confirm the stocks are made overseas, shipped here, and assembled. The B&C synthetic they use on the Extreme Weather just plain feels awful. I replaced mine with a McMillan Edge and it made a huge difference. The cheaper stock on the Ultimate Shadow is far better in my opinion.
I have 3 older New Haven made Winchesters and 1 FN produced gun. All are excellent and I'd highly recommend any of them to anyone looking to buy. Even with minor concerns.
