Check this link. Ammo to go usually has good prices. I would stay away from all the steel cased stuff in an AR (all cheap russian zoo animals (wolves, bears, tigers) and hornady training steel cased). All of the brass cased stuff should cycle fine. The surplus stuff will be cheaper, but the groups may show it. Its fine for shooting, but if you want match ammo, you'll have to pay for it. Check out the DRS reloads. Its reloaded using once fired lake city brass and hornady fmj. You'll get decent accuracy... but like I said if you're looking for sub MOA you should really be going with match ammo, or roll your own.

Really? A Rock River?

I always thought that was one of the better brands. I know the on I fired had a sweet trigger and no problems with what we shot, but we only put a couple hundred rounds through it one day. Sorry to hear it. Or, read it. Or - ah, forget it.
