I have a few Burris scopes, and like them.
I think the Nikon Buckmaster and Bushnell 3200 are comparable to the Fullfield II's, and are all good values.
Skeet, almost every bit of raw optical glass comes from overseas. Some companies like Burris, Leupold, and I think Pentax grind them here, but I don't think any raw glass comes from the US, and hasn't for a long time.
BTW, when I say raw optical glass, I'm referring to a big chunk of glass that's chopped out of a huge slab of glass- it looks more like a rock than anything you can see through. For many years, almost all raw glass came from a German company named Schott- and much of it still does. A few Japanese companies now sell some, too.
