Preserving an all-matching Kar98k

[Singer B]

Applying a “coat” or two of linseed oil isn’t a bad idea. Remember to coat the inletting as well.
Keep in mind the oil doesn’t go deep even in solid wood. Even less so on laminate stocks because the doesn’t penetrate the first layer of epoxy.
No reason not to oil your stock though.

Thanks, I didn't consider the epoxy for the laminates. Is it better to clean it with warm water or Hoppes prior to the linseed oil? I just want to remove the grime and crud so the arsenal markings in the wood will stand out more.
