You note a significant difference. Those top brands are pretty much in-house controlling most if not all production. Leupold assembles their scopes from foreign sourced parts. I think the last to be in-house was U.S. Optics. All of the good glass is either German or Japanese these days. That said, modern production has made even lower end scopes quite good and robust. There is the old argument... if you are going to the moon, do you take one Rolex/Omega or two Timex?All the big optics manufacturers have some sort of lifetime warranty. I’ve had the opposite experience between the 2 brands and of the 15+ Leupolds I currently own including a couple that might be older than I am, a newer VX5 Firedot is the one I had to warranty. I’ve never had to warranty a S&B, Swaro, Khales, or Zeiss though
