Default Tolerances?

Iíve been reading about aftermarket bushings, trigger jobs, etc. Basically it seems to come down to this:

Tighter tolerances = higher accuracy but lower reliability in dirty environments;
Looser tolerances = higher reliability in dirty environments but lower accuracy.

Yes? No?

Pretty much.........

With a tighter fit there's no room for any debris.

You would be correct. That's why the AK 47 and variants work so well in bad conditions, because of the loose(r) tolerances.
