I just won my first auction on GunBroker. Long story short, GunBroker states on their website that a FFL, signed in red or blue ink is required to complete a transaction. My FFL holder emailed a PDF copy of his FFL to the seller. My question is a emailed PDF copy going to be acceptabled? FFL holder says yes, haven't heard from seller yet. Just wanting to know where I stand here, as I don't want to get jammed up trying to complete the transaction. I have never used this FFL holder before, found him thru GunBroker.
