Just testing the waters, not really sold on the idea yet, but I'm looking for a 20" AR. Not really looking for a "target" type rifle; more of just a regular shooter rifle. Could be fixed A1 or A2 sights, could be a railed upper... I haven't really decided. What's out there? I'm not really looking to spend a lot of money, but it would be cool to try getting into the AR game.
