I have to admit that I am also thoroughly puzzled as to why the VPC has an FFL . . . anywhere.
You're not alone in that. I became aware of it in 2008, and I contacted the BATFE. They acknowledged that it was valid, and that the records hadn't been audited since 2002. When I asked if they were in the business
of dealing in firearms, I was forwarded to someone who dodged my calls.
At the time, the phones at the VPC office were not operational.
