Aero has a deal for upper and lower set for $220. That's a pretty good deal I'd say. It says gen 2, would that be a good set to go with?
Aero Precision is excellent quality. A lower is just a low-stress holder of parts, so unless you are looking for a specific manufacturer match or some such, an Aero Lower Receiver is all you need for a quality AR build. The standard Aero Lower even offers features that most name-brand Lower Receivers do not (eg. an inner tensioning system to eliminate Upper/Lower Receiver slop). A matched Aero Upper and Lower Receiver set is an excellent basis for a quality AR build!

Can this inner tensioning system be disabled or removed?
I dislike these gimmicky things that make takedown a pita with a 0 gain in practical performance.

RDSC.ca looks like they have some Aero Precision lowers and sets in stock. Not sure what quality they are.
