Welcome to FlyerTalk.
Seeking legal advice on an anonymous Internet forum is a bad idea. So is looking for advice on how to beat felony charges.
Just remember that making a false statement in writing on a Customs declaration or orally to a CBP Officer is a 5-year felony. Usually dealt with by a massive fine and a lifetime on a watch list.
There is also a very simple process for registering an item with CBP before leaving the US so that you have CBP receipt for the item upon return.
