Gator,
It was me. The good news is, you don't have to register any of your weapons with CA except ones they consider to be assault rifles ie. AK and AR patterns. You also don't have to worry about the Hi-cap mags for your non-assault rifle weapons. They are legal as long as they are legal in your state of legal residence. I'm not sure about Hi-caps with the assault rifles as I don't currently own one. Here's the e-mail I received from the CA DOJ Firearms branch with contact info.
This is in response to your recent correspondence to the Bureau of Firearms, regarding handgun registration requirements for active duty military personnel stationed in, but not a resident of California. Indeed, as long as you do not become a California resident (defined as possessing a California street address and a California driver's license or California ID card), the requirement to register any legal handguns you transport into the state would not apply, until such time as you become a California resident, as defined above. Bear in mind that any handgun transported within California without a concealed weapon permit must be unloaded in fully enclosed locked container.
I hope this information is helpful to you. If you have any further questions or need further assistance, please contact the Bureau of Firearms at (916) 263 - 4887, or via e-mail.
Sincerely,
Brent George

If I were you I would call them before you get here and find out what you need to know. Brent is former military and another guy, I think Bill or Bob, was as well. Brent said there wer quite a few of them in the office. They were courteous and very willing to help. I made the mistake of calling them after I got here having left most of my guns in Kentucky.
Are you coming here instead of Korea now? If so, where are you all looking at being stationed?
Take Care,
Bill
