I guess I'll have to break ranks.
My PWA lower was purchased from a board vendor not long ago, its serial 505xx.
Functionally, I have only two reservations; the lack of a weephole in the front pivot pin, and a magwell that won't let some of my mags drop free.
Cosmetically, I have more gripes. There are very visible mill marks on the front of the magwell, and on the rear strap. Also, there are some notable imperfections in the aluminum forging itself. The magwell "lips" are also gouged and dented in the aluminum. My Tangodown Battlegrip does not seat correctly, and is not flush with the rear of the receiver, because the grip area on the receiver is not milled well (this could be almost a functional issue) .
My friend's PWA also shows the same problems as mine.
The PWA isn't a bad choice, but bear in mind that other receiver makes are cheaper, have correct specs, and are cosmetically quite good. I recommend RRA personally.
