I NEVER buy into raffles. Aside from the fact that I suspect most are rigged... I usually can't stay for the whole event to see if I won. And it's usually a gift certificate to a bar or something... wow.
I would probably throw $5 into the raffle for a weapon like this. And it seems like it is worth it for the gun dealer, Atwood Armory, who just enjoyed national press as a result of their donation. It's a win-win.
