The most critical difference is the diameter of the area where the stock slides onto the tube. The mil spec buffer tube is about two hundredths of an inch smaller than commercial. This may not sound like much, but it's enough that buttstocks designed for one standard will not be compatible with the other.

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
