Ahhh the old 'torque it till it strips, then back it off 1/4 turn' lol.
To be honest I've never stripped any mounts and the BKLs are usually very good. Have they changed the specs at all recently?
I suspect you are referring to Moa and Mrad.

They are just different units of measurement for achieving the same result (hopefully). Mainly depends on your own personal preference for base 10 or imperial.
