If it helps in your decision I just built by first PSA lower kit. I purchased the Magpul CTR lower parts kit that includes the standard psa lower parts with magpul stock. I had originally purchased the standard psa lower as well and it looked very nice.
I decided go go the sbr route and since I am paying a stamp I wanted to buy a lower with a few more bells and whistles.I feel the psa lower would have been perfectly sufficient and would not think twice about using it for a non NFA build.
The PSA parts went together smoothly and arrived well packaged and oiled. I was a little disappointed in the stock trigger at first but after a few dry fires it is already smoothing out. I expect after a bit of range time it will be as smooth as any millspec trigger can be. I don't think you can go wrong with PSA parts.
