Exactly. I know a guy who lives in the San Diego area, who had a large collection of AR-15s; different manufacturer, different configuration, caliber, etc. He sold them all, every last one, for fear of running afoul of the CA Ugly Gun Ban.
This guy is a former Naval Officer, with security clearances up the ying yang, and his son is a Cop! (well deputy sheriff I think).
Now he's got a large collection of double barreled shotguns... different manufacturers, different barrels, different locks, hammers, hammerless, etc. Sick, just sick. (He really enjoyed shooting the M1919A1 and M-2 Carbine belonging to a coworker of mine when he came to "consult" on a project we were working on in San Antonio.
