Your going to see scopes going over seas as labor cost will mandate them to doing so. Burris is in Greely,CO I believe yet the fullfields are made in the phillipines.Labor cost, that is where it is at to be competitive in most markets. You can use quality parts and save on the labor making the end product high quality or equal to those with higher labor force cost.
I think you see those American scopes like Leupold going cheaper on glass and parts lately to offset labor cost, that in my mind isn't going to do them a bit of good. I like Leupold and have a vari x 2 3.5x10 great scope, but I went with a Burris 4.5x15 on a new rig I'm putting together, many say the adjacent other parts are of better quality than that of Leupold when comparing scopes in the same price range. I compaired the fullfield II's with a vari X 1 and II and nikon and found the Burris to have better guts and just as good a warranty and lonegivty from them as well. Time will tell if I made the right purchase.
