If it is a so-called a-salt weapon, then you can only sell it to a CA a-salt weapon dealer or to someone out of state. I think that the law says that only a so-called a-salt weapon dealer can ship it, but a person from the CA DOJ said that you could ship your personal so-called a-salt weapon out of state.
If it is not a so-called a-salt weapon, then it is just like any other long gun.
