I have 3. Dang good IMO. Sometimes the lower finish doesn't match exactly with the Anderson Upper, but that's true of most brands. The AERO I just put together was the same(finish wise).
Anderson makes decent LPKs as well. Their supplied SS trigger group will hang with much more expensive triggers with a JP spring set and a bit of polishing. One of mine is damn good after that treatment.
For $38-40, you can't go wrong with an Anderson lower.
