wooshna, we'd love to have you in AZ, that's for certain! As for various firearm models, I don't know if there is a Califonia Approved Roster for rifles or not. Pistols is there, so that would be easier to check for the Scorpion, which I do think is legal with the bullet button, and might stay that way being a pistol, don't know. Rifles, doubly uncertain, but I highly doubt there will be a CZ BREN Kali approved version, given the expense. CzechpointUSA MIGHT make a cali approved vz-58 rifle, as they have one right now they might be able to modify for the new rules.
Try CalNRA or other California firearms rights groups for specific answers - that crazy state's laws makes my head spin...and I work for the government!!!
