Ok, let's rethink this. I think fancy carvings look great on longrifles. They almost look unfinished without them.
This is different. This is a plains rifle owned by a grizzly old mountain man. He's a simple sort of guy. His gun gets banged around and is sometimes used as a club in a fight. He's the type who might take out his hunting knife and carve his name on a gun. Who knows, maybe his nickname is Bear Killer. So, he carves it on his stock.
