Anyone run a RMR on a Ruger MK pistol?

Hoping to see if anyone machined the Ruger receiver to allow the RMR to mount low.

Curious if anyone figured out a cowitness with iron sights.

Not enough metal to cut into the receiver and then thread screw-holes. There are some low mounts out there (http://www.maddmacsprecisiontactical.com/trijicon-rmr.html) but nothing so low so as to co-witness.
