I received the same message on the status page but wasn't too upset as I didn't know about the rebate when I purchased the gun in December; I wasn't counting on it. I didn't pursue the issue and was surprised when the rebate check arrived this week.

I have not taken my new Supernova down yet, but I have seen a youtube video of the takedown. There are two pins. You should be able to get one of the pins out with the cap. Then, use that pin to push the other pin out after you have started it with the nub on the cap.

I have a new Supernova tactical shotgun. It has about the same round count as yours; I shot 10 rounds through it two weeks ago and about 60 rounds in a shooting competition yesterday. It performed flawlessly with absolutely no misfires. I have never cleaned mine but shot it right out of the box. I will probably disassemble it today for cleaning. There is a youtube video that shows how to take it apart for cleaning. Sorry, I don't have the link. My gun's bolt exhibits the same 1/16" play that you described so I don't think that is the cause of your gun's misfiring problem. The pump action seems to be improving as the gun is being broken-in. One of the observers at the competition yesterday told me that the action appeared to be very smooth while I was shooting.
