Non-shooters who overpaid for ARs won't be in a big hurry to take a loss, that's for sure. A few things have to happen before all those new gun owners start putting their shiny new EBRs back on the market: (1) The legislative push to outlaw EBRs has to pass; (2) those folks have to realize that ARs aren't actually going to be impossible to get; and (3) as to each one individually, something has to happen so that a particular new owner needs the cash more than they need the gun.
A gunfight is not the time to learn new skills.
If you ever have a real need for more than a couple of magazines, your problem is not a shortage of magazines. It's a shortage of people on your side of the argument. -- Art Eatman
