Found a source for 5.56 & 9mm ammo...

[Feldgrun]

I'm not sure if this is the best place to mention this, but after searching 5 local gun stores in the Fredericksburg area I finally found one reasonably well stocked with 5.56 and 9mm ammo - SSG Tactical (https://www.ssgtactical.com/default.asp?) (no affiliation). Also many M4-type rifles and various handguns. Maybe it's because it's fairly new or that it's tucked back in a business district, but it's almost as though the onslaught of gun and ammo buyers passed it by. There are no super deals, but many things available.

They aren't new been there for a few years as far as I can remember anyway. However it did take me about a half hour to find the store front and I was using GPS. Good people there, couple of guys in my unit use them for nfa stuff. Thanks for the info though.
