I contacted leupold about swapping the mil/moa setup I have on my mk 4 for a mil/mil setup with the M5 knobs. They replied:

There will eventually be an M5 adjustment retrofit. I cannot say at this time if your scope will accept the M5 adjustments as not all older Mark 4 scopes have verified that the M5 adjustments will work properly or not.</div></div>
So, no new info but I thought I would share since there were some old threads about conversion that died a while back. Guess it's still in the works at least.
