I'm not an expert, but I do know you can sell or gift a gun to anyone who has a valid AZ drivers license, and you don't have any reason to believe is a felon who hasn't had their rights restored or been adjudicated as mentally ill, so why would a loan be any different? Unless of course you knew in advance that they were planning to use the gun in a criminal way. I've heard that it's illegal to kill bears for any reason in some state parks though. They expect you to carry non lethal weapons like bear mace or stay out of the bears woods. I believe I heard about Alaska state parks on TV a while back. A park ranger stated it. I would get in touch with rangers to the area your friend is going camping in to make sure. It would probably have more to do with hiking into remote areas than state camping parks.
