Member bafsu, no stranger to AR builds and components, and myself as well, have commended PSA, for staying within reason on pricing for quality stuff...the manufacturer, like gas prices, sets the price...
I paid $119 for a multi caliber POF stripped lower last year....for my Frankenstein build, with a Bushmaster lower parts kit for around $60.


One can still find DPMS stripped lowers for $70. +/-.....Which I also would be more than happy to throw two or three in the safe for a rainy day.
But PSA holds up...If demand is up,...prices go up.....I think Brownells has Armalite stripped lowers for $150 ish?
Easy on the turnip greens,....

The LaRue stuff, is off the charts for pricing, but IMHO, is not needed. Just comes down to preference.
