Are automatic weapons legal?
Automatic weapons are legal to have under US federal Law. You can only buy one that was manufactured and registered before 1986. You have to go through a class 3 dealer and get it cleared with the ATF before you can buy one. This is the Federal Law. Your state law, since CA, most likely has their own restrictions on automatics. http://www.nraila.org/statelawpdfs/CASL.
