I have a magnetic gun rack that sticks to my truck fender. I stack hot guns there with open bolt. After I've shot a couple of others, I can start over with the rotation.
Just gotta keep good records as you go.

Just don't back the truck up too.
No, gotta leave it where you park it.
I have a better bench, this one is easier to set up. I even redesigned this one. Have a better version.
