I've been told before that I must be charmed, as I've only ever gotten 1 lemon in my personal firearms history. Not a bad run since I've owned close to 200 guns over the years. I prefer to think I've got well calibrated eyeballs. My first personally owned AR was a collection of junk that I built, but it ran like a scalded dog. Didn't really like it a lot so after a couple of years I sold it, then came a PSA that I built from a kit, and it's still running hard, gets shot almost daily by the guy I sold it too. Assembled my nephews, assembled my BILs, both still running, but those were built from parts they could scrounge while living in the not so pro-gun state were they have to reside due to employment. They did listen as best they could while searching for parts. A good friend of mine, owns an Oly that he's had since the late 80s when that was almost all that could be found. We make fun of it as we are shooting it at the range. It's still chugging along.
