I believe having a rifled barrel makes it a rifle, not a shotgun. That is why the Circuit Judge is legal in CA, even though it has a "revolving cylinder."

Edit: I see, you are saying LEO "could" arrest you, "theoretically," if they felt like being jerks?

Runs into the fact that most CA LEOs are typically not knowledgable about firearms and CA firearm laws.

So, when they see a firearm that is commonly a shotgun, they tend to treat it as such. Because they do not know how to examine/check that the shotgun is not really a "shotgun", they fall back to the "hook & book, and let the lawyers figure it out" mantra of training when dealing with possible felony violations.


When they were first introduced there was some hand holding and CA DOJ admitting that the Rossi Circuit Judge was CA legal due to it not meeting the CA definition of a "shotgun", before vendors started to sell them in CA. Because initially, LEOs and vendors thought it was CA illegal as an assault weapon.
Back in 2013, the CA legislature even tried to amend the laws to make it an assault weapon (SB 567), but CA Governor Brown veto'd that attempt.

It shouldn’t need a fixed mag if it were used on a BBRAW. Also, if the receiver were a BBRAW, why couldn’t it be used with an adjustable stock and pistol grip?

Would it matter if the registration indicated multiple calibers?
