I just bought a complete RRA upper from SABLECO.COM, for $380. It's the cheapest that I have found on the internet and the gun show. It should be in by Monday or Tuesday. Donnie Pridemore runs the business. His email address is on the web page and it appears that he checks it quite a few times a day. I emailed him twice in one day asking questions and received answers both times the same day. As a matter of fact both times I was at work and when I checked my email I had responses from him. How's that for service.
