I've faxed at least 5 multiple handgun reports to the ATF this week. I plan on doing another one tomorrow with 8 handguns on it.
I think the ATF would let me know if this was a problem.
It sounds like to me:
1. The dealer is using ATF to only sell one gun at a time.
2. The dealer really doesn't want ATF looking at his records which multiple gun sales COULD bring.
My thoughts.
