Completed lower storage

[Gundiver]

I bought a completed lower before the deadline to stash away just incase my other ar 15's got stolen or vaporized. Does this lower need to be treated as a RAW and stored in a safe that only i can open? I'd need a separate floor safe or something since the whole idea was to not put all my eggs in one basket and hide this one away.

Also, this is so stupid but if i stash it under a floorboard or something along those lines would it still need a cable lock through the mag well? Hahaha - absurd but I really need to know.

Someone please correct me if I'm wrong... but I don't think there's anything to worry about until it's attached to an upper receiver. It's my understanding that a lower receiver, in any state, while NOT attached to an upper receiver is not a complete firearm and by logic cannot be an AW.

Depends on what kind of upper you have in your possession.

Right now, nobody really knows. Until the DOJ releases the regs, an overzealous cop could charge you with construction.
Play it safe.
