You can bring it there, your not going to get it back. in 06, one of our guys dad was a cop and sent him a glock, he kept it on the DL for a while, then got caught and go in trouble. bye bye glock.
If it has that much importance to you as a family heirloom then leave it here.
That being said, if you know a medic you can unscrew the tops to the oxygen tanks, wrap it in bubble wrap and seal it up on the tank on the way back. I know of an LT that owns a few AK's from doing that.
