Take a look at AR-15 Performance for any everyday, no frills, decent shooting barrel.

AR15 Performance^^^^^^
x3.
I have two of their barrels (a 12.5" 6.8 SPC-II and a 16" .223 Wylde) and with handloads, I've found sub-.5 MOA loads for each of them. I have had one of these barrels (the 6.8) for a few years (the other is new), and it has shot sub-MOA with every factory round I fed it. Plus they're a great deal at about $180 each. Hope this helps, but YMMV.
