Negative. The reason that people do not see issues with optics is because-
1) They don't test them for function.
2) They make excuses for why shots miss.
3) They change ammo constantly, always playing and therefore never could notice when POI changes.
And
4) The biggest reason is that very few actually shoot enough for it to matter.
I test optics initially upon mounting by zeroing correctly, testing tracking, return to zero, and drop "testing". I then confirm zero every time the scope is used with the exact same lot of ammo as it was zeroed with and log it. It is obvious when a scope loses zero or fails to adjust correctly.
Seeing as many optics as I do a year, with as many rounds fired... trends show quickly. And it's not just from thousands and thousands of rounds fired either. Lots of scope do not function correctly straight out of the box and/or fail within a few hundred rounds.
