Please reconsider - why can't you ship Stags (or other off-list lowers) to California? [Some/many Rock Rivers may be listed in CA so we'll stay away from talking about those for now.]
Why are you volunteering for voluntary gun control that's not mandated by any law?
If you talked to Ca DOJ (or are relying on what Stag said) you were likely talking to a DOJ agent by the name of Dana McKinnon. He's been the bad boy doing scary phone calls to vendors.
Fortunately many vendors are ignoring him since they know the law and the 2001 Harrott decision.
In summary: any AR-type lower that is not on the DOJ Roster of AR15 and AK Series weapons nor in PC 12276(e) or similar Calif. Code of Regulation sec 979.11 is good to go. This means make AND model.
So no Bushmasters, Colts, Armalites, ASAs - but newer brands that came out since 2000 like Stags, Fultons, SunDevils, etc. are fine.
DOJ phone folks - esp Dana - appear to be quite unfamiliar with details of California's assault weapon laws, and/or insists to non-Californians that the law disallows things it actually doesn't. And they haven't told you at all about the CA Supreme Court's 2001 Harrott v. Kings County decision, which says that AR and AK lowers are not illegal/banned unless first declared as such by DOJ and then added to California Code of Regulation sec 979.11. (Of course, these couldn't be built into working rifles w/detachable magazines after 2000, but they can get pistol grips put on them if they use 10rd fixed magazines so they don't violate SB23 'evil features' rules. These will likely be declared AWs in future and after registration can have evil features attached + detachable mag.)
CA DOJ is very embarrassed as they had a chance - for FIVE YEARS - to update this list (called the Kasler list, or the AR/AK Roster) and they did not do so.
Several thousand "off-list", non-Kasler lowers - including Stags - have already been LEGALLY brought into CA and have been legally sold to individuals. DOJ agents have even stopped by gunstores doing this business and have acknoweledged it's legal. (If it weren't, many FFLs and gun owners woulda been arrested over the last month.) The DOJ agents are even gathering DL info from the bulk off-list lower vendors to send out registration cards.
We have enough trouble in CA without having our 'friends' help the gun controllers.
Just remember this: you're doing what Sarah Brady wants you to do.
And you are not required to do what the DOJ 'asks' you to do.
Stag itself is unclear on this.
If this was illegal, Californians who know the laws would not be doing this, and people (customers AND CA FFL dealers) would be arrested already
