The standard VR80 is not CA compliant, but RIA makes the VR80CA which is compliant, they look the same at 1st glance but the CA compliant version has a fixed magazine that requires you separate the upper receiver from the lower receiver to remove/replace the magazine.
Copy and paste from the manufacturer
"The VR80CA 12GA shotgun is a semi auto magazine fed firearm that is legal for California. This gas-operated semi-automatic 12GA shotgun has an upper and lower receiver constructed from 7075 T6 aluminum similar to the AR15 rifle series. The VR80 CA Legal provides the familiarity of AR-15 ergonomics and controls. It's magazine fed firearm with 5 round capacity of 2 3/4" and 3" shells & you can legally use optional 10 round mags. For California legal Operation you simply pull the rear pin and this opens the gun allowing you to push the mag release and remove the mag. Insert a new mag and close the gun and you are back in action!! "

budsgunshop.com/product_info.php/products_id/124611 />This one has a standard detachable box magazine and would not be legal in CA
