Hey Lloyd,
From what I found out from my optics buddy is this. He said prior to 2009 Pentax glass was made in Japan , and assembled there.
From 2009 on, the glass for the higher end Pentax is still made in Japan and assembled in one of 6 places. China, Vietnam, England, Phillipines, and I forgot where else. He said there are only about 12 places in the world that assemble scopes, even Leupold is assembled in Phillipines. He said about 80% of all scopes are assembled in the pacific rim, which I guess is Asian countries. Then you have the European stuff, He said even Burris models below the signature and diamond are overseas. He said there is very little made and assembled here anymore.
