Yeah, and its always YMMV, I enjoy tinkering IE trouble shooting ARs... those are fun things for me. Not so much for others I get that but I forget that in comments often.
No denying, if you spend money on a known, the odds are always higher of working and accuracy.
OTOH you can get there other ways as I constantly say.
But then again I know whats important in an AR for match shooting, where I have to spend money and where I can get by with cheap...
We all have our nuts moments. I may have more of them than anyone else over here on 24 hour...
