John, I just had a good one happen. A new scope had foreign material on the internal glass surfaces when I took it out of the box....looked like oil spots, likely from assembly.
I got the authorization to send it back and did so along with a detailed explanation. Two weeks later it came back with a work order that stated 'Replaced erector assembly and reticle."
'Ya gotta' laugh. But at least the spots are gone!
Good shootin' -Al
