If I could find one of these at a gun show - where I could pay cash for it - with no names - I would get one and put it away for SHTF. Other than that - I wouldn't be putting my name on a list.
I'd rather have a Magpul stock and a decent trigger. This thing is a "fun range toy" but I don't see a practical application for it. It's the type of thing you would put on that bastard child AR that is sitting in the back of the safe that never gets shot.
