Discrete import marks do not bother me. The Century Billboard is a little too much. I do however avoid import marked K98kicon rifles, but if the price was low and everything else was correct I would possibly buy one.

I'm sure plenty have bought rifles that the import mark was removed. It's unethical IMO to remove an import mark but perfectly legal.

I've purchased some rare South American Mausers that have German Proofmarks and then upon import my importer laser engraves their mark under the barrel to the minimum requirement by law. You can barely see it. The German marks stand out but I think they look kind of cool and they tell the story of where the rifle has been.

My understanding is Century puts the giant billboard because they are misinformed by their local ATF agent. The giant billboard on the receiver is only required for semi autos, not for bolt rifles.
