Im thinking a lot of these guns and much of this ammo might find its way to the secondary market when this dies down.
In practice this doesn't happen because most of these people overpaid for their shit and they don't want to get hosed..... so it sits in a closet somewhere. I didn't see a flood of stuff come back in after obamascares 1/2/sandy hookmaster. It's probably still collecting dust in closets.
