Scopes aren’t electronics. The are steel, glass, brass, aluminum, glue, screws....
First off, the market for a simpler, less feature rich and reliable scope is much smaller than you think. Almost laughably small. How may conversations have you heard from normal hunters where they talked about the unreliability of scopes in general? Probably none. Until the general hunting/shooting population starts realizing that the reason that 600 yard shots are “hard”, whybthey hve to check and change zero every year, and that some of thier misses are optics failure- you’re not getting manufactures to change where the focus. The only way that people will recognize there is a problem, is if they start shouting and practicing like a dedicated bow hunter. Until then, they’ll kill deer at 200 yards, they’ll miss some, they may even have a scope failure. But as long as they have that great warranty- who cares....
I’ve talked with one of the best scope manufacturers about a lighter, less feature rich scope. There isn’t a market for it. Even if there was, they could get a simple 3-12x40’ish scope to be reliable enough to meet their standards at about $2,000. And..... it would still be 17-18 ounces. You show me a group that will spend $1500 more an a scope to save 1-3 ounces with less features, less mag range, no illumination, etc.
