Why do people think that makes the rifle worth less? I am probably going to be hammered for saying this, but I don't really want to sell a firearm to anyone who can't pass the background check. We do exactly the same thing in person, I don't think most people here would sell a gun to someone they thought was a criminal or mentally unstable. So why is this an issue with my listing?
Some folks just don't want their firearm info available to the authorities OR the public. It's not a matter of passing a background check, it's more a matter of not knowing what may happen in the future. Remember, the authorities in 1920s/30s Germany had all sorts of seemingly logical law-abiding reasons for everyone to register their guns, with all sorts of promises that no one would lose anything.
I think we all remember what happened then.
In addition, the info is also available to the local gunshop hangers-on, some of whom WILL gossip about the valuable guns that old Joe is just BOUND to have squirreled away (grin). Some of this gossip may reach the ears of burglars, politicians and other lowlifes....
All in all, I personally much prefer as little notoriety as possible.
Regards, Joe
