I had the old Redfield Denver made scopes for a long time. I had over 40 at one time. Most were the accutrac models. About half 3x9’s and half 4x12’s.
I’ve slowly changed to Talley split rings and VX III’s. I have sold most of the old Reds here in the classifieds. Of the 40 or so Reds 3 have gone bad [ internal adjustments stripped] optics still clear. That’s about 8% failure, but all lasted at least 30 years. If a scope lasts that long and goes bad is it a failure or is it worn out? If my truck makes 160,000 thousand miles with no major BS I think it’s been great, but worn out. I took caps and dials off those three yesterday, threw them in trash.

So, how long does a scope need to last to be considered a good scope. Should it last forever?
