Some do and some don't, the one I had (traded for a Kimber)had a one peice stainless bbl,Guess it depends on whom you buy from, and how long it's been sitting on the shelf,I belive they went to a one peice bbl last year,However, Springfield says that the Mil-Spec will now be assembled compleatly in Brazil, Before, they were just buying the finished frames and slides and assembling them here in the U.S.So, ones marked "Brazil" on the frame are made there
