I saw one that was 1 MOA, with iron sights, in 223
Shooting that well at maybe 100 yards is pretty tough on the shooter. I wouldn't be able to tell how well a rifle shot at that distance without a scope these days. Maybe 20 years ago I might have stood a chance but no way now. That's some real shooting.
And of course real quality doesn't come cheap. I know people build some AR's that are mighty accurate. They don't come cheap either. And they don't spend much on making them have classic good looks.
