Good news! M1 Carbines dodged the bullet.
Information only for M1 Carbine owners in California. I don't want this to turn into a political firestorm so Mods plese lock thread, but leave up for information.
Gov Brown sign a bill making almost all centerfire semi-autos as registerable Assault Weapons effective 1-1-2017. The M1 Carbine (and Mini-14) ARE NOT included because they have no "evil" features.
All magazine of any type greater than 10 rounds, however, have to be turned in, except for active and retired LEOs. If you have a carbine in California, pick up some 10 rounders.
