The K-mount registration distance is 45.46mm,
while the Leica R distance is 47mm.

So with a K-mount lens on the R,
you'd either lose the ability to focus at long distances,
or you'd need an adapter with internal optics
that would degrade the image.

AFAIK, the only way to have an FA 43 on a Leica
is to mount the Leica M version of the lens on a rangefinder body.
