Yahoo!! Guns and parts will flood the market. Happy times for those guys looking for bits and pieced to force-match 1944 Winchesters to flip back onto the market. Aftermarket stocks, barrels and scope bases will be back on the market. If the ammo suppliers are on the ball, they will start the lines to load pallets and containers of 30-06 M2 FMJ. There will be A LOT of demand for shootable ammo that can be shot by newcomers without having to learn how to reload.
On a deeper level, this is a sure sign that the US sport shooting culture is thriving. The election of Obama changed ambivalent gun owners into enthusiastic gun buyers. As these people get guns, it stands to reason that another generation (or regeneration) of shooters and competitors will emerge. This is only a good thing.
