Their quality glass starts with the elite 3200,4200,6500. Those are from japan, from there down it's made in china.
Having said that, i have two 6-18x50 banners that work great, up to 12-13x, after that i have to work a little bit to make them focus, that may be my eyes and age.
I also have two 3200 5-15x40 tacticals that just flat work great. Theopticszone has the best price i have found. Bushnell stands behind their products, but they are always 6-10 weeks behind. blue
