I have found a way to build my own for less than $650 !!! I found a Wilson Arms mil spec complete upper with 16" chrome moly barrel. It comes fuly assembled with complete bolt and carrier assy installed, and includes A-2 or A3 stock and parts kit a lower. $485 + shipping no FFL needed. From the same company I can get a DPMS stripped lower for $110 + shipping + FFL (approx $145 total). Or Bullseye in Lawrenceville sells stripped Stag lowers for $130. Richard at Bullseye in Cumming told me that he will assemble it for $20. Any idea about which lower I should get? And what's the differece between an A2 and an A3? The ads give the option of .223 Rem or 5.56 NATO. I thought they were the same? Who locally has a good price on AR mags? If I wait for the next gun show I won't be able to shoot it on the 16th.
