I did a quick search but didn't find anything, and I'm @ work so I don't have time to pour through every old thread.
I know CA doesn't have constructive possession laws, but we do on the federal level. And it's been discussed here many times "blah blah yes it's legal to own a short barrelled upper sin SBR paperwork if you don't have an AR lower blah blah."
What's the legality of building/owning an AR pistol if you already own AR rifles? Is there a loophole there or are the feds going to say "you can readily combine upper from pistol A with lower from rifle B and construct an illegal SBR, therefore you are a felon here are some bracelets."
