I really wouldn't get my hopes up on either gun, not because they are bad guns, because I haven't been able to find anyone who imports them anymore. Any CA MP5's that is. Mabey I've just checked in all the wrong places (but still a hell of alot) but I still haven't found anyone who currently can get these.
That doesn't mean you won't though.
If you do find someone who can get the MP5 series, give me a PM.
