What if someone wants to move to CA and legally owns one where they currently live, are they able to register it within some time period upon becoming a CA resident???
sorry...illegal to import any already banned by name or having features that fall under the definitions.
if your's isn't banned outright, you can either go the featureless route or add a bullet button mag release.
my opinion is the the featureless route is easier and on more solid legal footing than the bullet buttion....and if you go with the Hammerhead can still be pretty good looking
