I would say that:
-Sub-MoA rifles are uncommon
-Sub-MoA ammunition is common, but only in handloaded rounds
-Sub-MoA shooters are rare indeed.
For the rifle, the best out-of-the-box rifle that's actually useful (read: good for more than just taking three or less shots at an animal in the woods somewhere--e.g, an "evil assault weapon") is a DPMS Panther .308. This thing is easily capable of 3/4 MoA, and possibly even .5, out of the box. Of course, using handloads for any shooting in which extreme accuracy is required is essential...
