About those illegal blank firers - Has anyone tried to do a chargeback?
I think there is a limit of 120 days for a credit card chargeback, but if I had bought one of those blank firers within that period, I would at least try.
Whoever you bought it from sold you an illegal Section 5 firearm, misrepresenting it as a legal replica. It was then confiscated from you by the police. Seems like a chargeback would be a slam-dunk.
