It is clear to me that those who wish to ban guns do not know what it is they are talking about. This is clear because they so often claim they want to ban things that are not an issue and base much of their demands on subjective issues (looks) as opposed to am argument based on the actual workings of the firearms in question. So, my idea: A gun maker should design an AR-15 style black powder rifle. Cosmetically it would would all scarey and subject to the ban the gun grabbers want. Mechanically it would be a black powder rifle. Then as it gets advertised see if it ends up subject to the ban, as I suspect it would. I do not have the means to make such a weapon. In payment for my idea I would gladly take one of these new rifle.
