what i failed to see is who made you the "moral" police? and whos to say the "fools" (you called them) wont sell it at a higher price next year?
What a puerile argument.
Flippers, like scalpers or pay day lenders, are still scummy. Legality does not infer morality. People are right to look down on them and avoid such practices.
If you feel like paying $2000+ for a 6 MOA rifle that sort of looks like an AK, have at it. Just don't complain when you go to buy ammo, only to find that the fat p.o.s. in front of you has bought up 20 crates of it, only to sell at a gunshow at huge mark ups.
