Palmetto has upper and lower FDE for $380 shipped...
+/- $400 with taxes to your FFL here in GA. A deal, but I still can't justify another plain jane AR.
I hate internet taxes 
Nah, thanks though. I'm a Fourth Armory kind of guy.
Again, for a little more money buy an M&P Sport II and actually know the specs of what you're buying.
Where's the fun in that?
