Beat me to it.Well, here you go. Tightest Tol (I did not look super hard) was .0015" (Fifteen ten thousandths). Far from a Millionth.
If there is no tolerance on a dimension, than that dimension defaults to either .005" if three decimals, if two decimals, than .01"
I know some of the boutique lowers are built to a better tolerances as I have seen other prints where .001" was used much more than on this one...
