UPS, not so good IMO. Ship USPS. No problems there. And as far as 'what's in the box' questions, firearms of any type are subject to theft. I would never say that a gun is being shipped. (Not saying you should violate any law), but if your actions are legal, why reveal to a stranger that a weapon is being shipped? The 'machine parts' reply is perfect. It is the truth, and keeps the nature of the contents of the package safe. Just my .02.
