I was in Vegas a couple weeks ago and the place there would rent me a full auto subgun to go.
I'd pay the rental fee and leave a deposit and lots of documentation, but they would turn me loose with an Uzi to take to the range or home or wherever.
Never heard of such a thing, but I asked in depth about it. They said their (indoor) range would not handle the full auto guns, but I could rent it up to 24 hours and take it to the range to shoot.
We were there on business and I was just touring the shops I drove by. But, I guess you can bring some rentals home.
I only live 75 miles from Vegas. Sure would surprise the guys at the IDPA match if I showed up with a sub-gun. Have to give it some thought.
