Since he was running the S-corp as a sole proprietor, gross receipts gets reported on Schedule C of his personal 1040. These numbers are before "cost of goods sold" is subtracted. But while there's money involved in 3-8, I would be more concerned about the first two. I've dealt with ITAR restrictions, and you really don't want to export controlled items (firearm parts) without the appropriate licenses from State.
Guess I won't be building that G3 kit I had my eye on.
