SBR lower receiver

Hey guys simple question for ya. I live in the wonderful state of California but also reside in Nevada where I do have an NFA trust setup. My question is can I get an SBR AR lower and bring it into CA if I configure it to CA law…sigh
16" plus barrel and a mag locking device?
reason being so that I could shoot here in CA and when I get back into the land of the free (Nevada) I can swap the upper and remove the maglock.

Probably sounds stupid to a lot of you but unfortunately we have to be intelligently creative in this god forsaken place

If a given lower doesn’t have a barrel mounted that’s less than 16 inches, it’s not an SBR. The rules that pertain to it are the same as any Title II firearm. You can put a long barrel on it and do anything with it that you could do with any rifle that’s legal in the state where you are possessing it.

Other than the lower being engraved right?

If it doesn’t have a short barrel on it, it doesn’t matter whether the lower is engraved or not.

You could engrave the upper if you wanted. (I wouldn’t, just saying it’s an option).

Engraving it doesn’t change what it is. You could engrave your trust name and location on a screwdriver, and that doesn’t make it an AOW. It just happens to be a legal tool you engraved your information on.

Any reason why you wouldn’t just build a cheap lower to use in Cali? Seems like a lot of unneccessary trouble to swap parts back and forth.

Yeah it is but it’s a rare lower that is impossible to find that mates up to a specific upper. I know it sounds rediculous…

Then just have a Cali Compliant setup for it and accept that it’s going to look stupid (because that’s what Cali legal system does, makes things stupid), then be able to return it to a non-retarded configuration.

Lol good point, I was thinking about doing it as well as just wanted to know for gp
