I'm not sure what the Swissicon used as a finish for their wood, but you may be surprised at how close the handguard and stock match up once you get the stock hydrated and coated with the correct finish. The other option is to strip both pieces down to the bare wood and start over with the finish you prefer (RLO, BLOicon, stain, etc.). I have a feeling that you are going to have a great looking K11 that shoots well when you are done.
