Looks like good stuff, but aren't they just a tad proud of their product... uppers STARTING at $1400.
Until now I had not heard of these guys, that obviously doesn't mean much. Other options I'd suggest you at least research would be POF and the XCR. Both are going to be right about the same cost for the whole rifle and in some cases more features for less.
Just an option, but to answer your question, it sounds like a fair combination if you want to drop that kinda cash. Then again you might consider just getting a whole rifle from them. Price wise, if you take out the $1400-$1600 just for the upper, their lower assemblies appear to use fairly high quality add ons like MagPul stocks and so on.
