I just bought a ten point cross bow, and the first thing my stupid boyfriend did was dry fire it. It's been shooting fine, but I just noticed what appears to be a chip in one of the limbs. I can't tell for sure though. I don't know what to do. I don't know if the warranty will cover it because some idiot dry fired it. Also, I can't figure out how to change the battery for the scope. It's a quad 3. Can anyone help?
