I think it was suggested earlier, but some kind of coating to kill the wood grain would make it look a *lot* better. Maybe a thin layer of bondo?
After that, maybe a bit more detail is in order..
One thing that could help is to cut off the laser pointer nub you have, drill a hole into the wood, and insert a real one. On a lot of the cheap little 5$ ones, when you screw the dome off they have a neat-looking machined head that would fit the aesthetics of the M6 pretty well.. and work to boot.
