I went to Sacramento (SMF) yesterday to get updated 4457’s for 3 of my rifles. I had filled the forms out ahead of time to save the CBP officer the trouble. When I handed him the forms he noted that I did not have the scopes listed. I told him I’ve always been told by other CBP agents to not to bother including the scope. This agent said I needed to have the scope on there for my own benefit and he wrote them in for me. Even doing that for 3 rifles, I was out of there in about 5 minutes.
The CBP agents in Sacramento have always been easy to work with. Good guys, friendly and efficient. You have to make an appointment, no walk-ins, but I’ve never had any issues getting in & out quickly.
