I copied this information from a post on RimfireCentral.Com & it makes for some interesting reading:

Most of us are at least familiar with the ultra quality of US Optics riflescopes (in the $2000+ range). Here is an edited quote from their catalog that should be interesting to US Optics freaks....
...........................................................
My name is John B. Williams Jr. and I am proud to say I started US Optics and I own and run the company proudly.
After working in the firearms industry for almost forty years, I recognized the need for an extremely high quality line of American made custom telescopic sights that would give shooters what they wanted and needed, not what some American, Japanese, or German company president (who usually didn’t/doesn’t even shoot) thought the shooter needed.
Today, most Japanese makers have gone to China for their lenses. Those lenses show up in Japanese scopes sold by many of our American and European competitors. No other scope company that we know of in the world today makes lenses for their scopes in their own factory, under their own supervision. Almost all of the scope companies have the entire scope made in the orient or elsewhere. Some of these companies have attempted to assemble the Oriental components here. Leupold and Burris build here and do a good job, for being “production scopes”. They do not build any lenses in their plants.
That is not to say that our custom made U.S. Optics scopes are made totally here. That is not true. Switches, springs, raw glass, pressings, lens coatings and anodizing are some of the minor things that we sometimes buy outside our plant. This does not necessarily mean offshore.
Let’s get some facts absolutely straight. Most of the German made Schott glass (Mainz Germany) is some of the very best in the world today but is not always available in some types of glass. If we can buy better glass somewhere else we will sometimes do it, because it simply does not matter in the way that some people think it does. Gentlemen, if a lens or lens system meets full and complete manufacturing specifications, from a technical point of view, it does not matter in the least where it was made. I have seen some types of glass sold by Schott offshore that is better than that of most optical glass makers. The Schott glass factory in Duryea, Pennsylvania (a subsidiary of Schott Glass Germany), makes fantastically good glass, but don’t let people tell you foreign glass is not as good as “American” or “German” glass. Ask them to prove it-as it simply isn’t true and all of those in the optical field know it (if they really know their job). Yet, you will hear the same old tired phrase, “if it isn’t German made, it isn’t as good”, or “German glass is the best”.
It is a well known fact that Leitz of Canada (formerly a German company, now owned by Hughes / Raytheon), uses Ohara Glass (a Japanese company) and produces some of the world’s best lenses (made in China). They were doing that well before Hughes took over, I know, as one of my people worked there.
Interestingly, you will not see lens grinding, polishing and centering machines in the other scope making companies. Most manufacturers either have their lenses or the entire product made by someone else. Most Japanese scopes with American names use Hoya Lenses made in communist China.
I thought this was interesting.
