I'm building my first AR and doing it piece by piece for the lower but going to buy a complete upper.
Right now I have a .223/5.56 Stag Arms stripped lower, RRA lower parts kit and RRA stock.
Far as I know AR parts are pretty universal - but are there any complete uppers that won't fit well with that combination? I'm looking for an A3 upper of some sort, and have bene primarily looking at RRA, DPMS and S&W uppers so far...
