the manufacture, sale, or possession of imitation firearms, as defined, and that those provisions shall preempt and be exclusive of all regulations relating to the manufacture, sale, or possession of imitation firearms, including regulations governing the manufacture, sale, or possession of BB devices and air rifles, as specified. Existing law defines "imitation firearm" to include a 'BB device' and defines a 'BB device,' for specified purposes, to include any spot marker gun
it looks like De Leon is trying to follow NJ810
this is confusing though:
(b) Notwithstanding subdivision (a), the County of Los Angeles,
and any city within the County of Los Angeles, may enact and enforce
an ordinance or resolution regulating the manufacture, sale,
possession, or use of a spot marker gun that expels a projectile
larger than 16mm.

If you do a little search on the CA legislature info site, you'll see a number of bills that he's authored which are pushing (some appear successful) to impose more regulations and restrictions on gun owners of all types.
