That if you leave your gun at a repair shop or range for more that 24 hours that they have to log it in and that you have to go through a background check to get it back? Even if you own it! My local range just went through a ATF inspection this week and that is what they said. I left a pistol to be sold. If it does not sell, then I have to do the paperwork and go through another background check to get it back. So, before you leave that rifle to be sighted in or have gunsmithing done, be sure that you are "clean" so you can retrieve your own property.
