Well, as dumb it is, it’s not legal to sell large volumes of guns and ammo without a federal license. Especially where the guns sold were not acquired for the personal use of the seller in the first instance.
Also, the bigger problem is—you’d assume—promo stuff that’s not put back into T&E circulation would end up on a prize table or raffle for the benefit of the org.
Not sold on a local gun forum under some guy’s personal account.
