I agree with jwc007. Send that puppy home! Even if you could fix it, it would be better for them to fix it because they need to know such problems exist so that they can prevent it from happening in the future. You'll want to eliminate the "we shot two rounds through it and couldn't get it to malfunction" excuse, so definitely send the video along with it. Ask for them to let you know what repairs they had to do. Let us know how it works out.
