I've had zero problems with the 5 or 6 PSA lowers I've built. I remember reading somewhere that most brands are forged by the same company. I built my first AR in 1994 on a PWA lower and a Bushmaster upper. It's still my go to war rifle.
Some PSA lowers are made by Aero Precision and others by unnamed "mil-spec contractors".
