"Vetted? What does that matter if the mfr provides Lifetime Transferable warranty and does warranty repair in KS?"

This attitude drives me nuts. I've had scopes die on a couple different hunts and the warranty meant nothing at the moment (I've been packing backup rifles, bows and optics on my trips for decades now). Most of the low end optics we've been inundated with carry lifetime warranties.... The scopes I've had go bad were immediately sold after repairs because nothing would restore my confidence in them. Sorry for venting but I buy things banking on their functioning.

I've looked into some of the higher end new brand scopes and view them like new model American made vehicles: I'll let others help the company work the bugs out for a year or two before sending my money their way.

Yes, all things mechanical can break--I've had it happen even with some top shelf optics.
