California is absolutely coming for workarounds like this next. Look at where we are now where California is at the point where it is pivoting to stop people from assembling firearms (sometimes 3d printed) using parts from online retailers and controlling barrels.It's telling that the only badge-verified FFL to post in this thread about all the things that will now be subject to new restrictions came here to reply to the citizen's workaround with 'no u can't do that!'
Probably speed dialing lobbyists in Sacramento to go after virtual mailbox shipments to California now.
The state will sue gun retailers based on the idea they are selling to California residents through proxies and retailers will start doing stuff like refusing to ship to any virtual mailbox or process any orders with a CA billing address. Maybe they sue virtual mailbox companies over use taxes. They will extend California jurisdiction as far as they can.
