I asked him if it was always like that and he replied that it was--that it was first come, first serve and with folks always waiting on the shipments they handed out numbers when someone came in early and waited. On a hunch, I asked him if it was always the same 3 people waiting and he replied: "Pretty much."
I got pretty much the same information from the sales guy at Academy Sports. He said they put the stuff out each morning and folks are lined up before the store opens to buy it. So, they started limiting purchases to one box per individual and folks started showing up with friends. He speculated that they were from smaller guns shops attempting to augment their supply.
