I have lots of AR's that I've built, and generally I make them to be as accurate as possible as most of them I aim to get teeny weensie groups as far out as possible. Have lots of money in expensive optics too. Most of them are in fact very accurate. They also tend to be quite heavy with long, thick profile barrels.

The one AR I have that isn't all that accurate--about 1.5/2.0 MOA +/- at 100 yds--is a mil-spec grade lightweight carbine with chrome-lined barrel and a small red-dot on top. It is very light, very quick and I don't worry as much about problems with the barrel if the going gets hot. It's my go-to home defense AR. Accuracy is a matter of perspective depending on the situation I guess.
