If your base commander and the armorers will sign off on it, I'm pretty sure you can store your personal NFA weapons in the base armory.
Then you should only need to do the nfa interstate travel notification form when you move them into and out of the base.
I don't think you would be able to use them outside of the base within the state of CA.
I doubt your base commander and armorer will sign off on it though.
Are you military? While it might be true that military bases are federal land and etc etc, Base COs still want to adhere to CA laws. I don't know with Army or Airforce bases but with the Navy and USMC your weapon have to be CA Compliant when you register it.
