I shoot a lot of subgun matches and am happy to lend an Uzi out if someone needs one. Sometimes the person will be in a different squad. We always make sure we place shooters shooting an unfamiliar gun with our best Range Officers. Better safe then sorry. ATF has told me in the past that as long as I was on range property I could lend guns out without it being a transfer. Have they changed their mind and I now have to be the RO for anyone I lend an Uzi too.
