Ok guys, take off the tin foil hats...real simple its just a part, its not even some sort of "suspect" conversion device (unregistered drop in auto sear) it just an "factory" AK auto sear, go buy an AK parts kit and unless the importer/distributor pulled it, you'll have one too. Is it of any use to most people, nope...but nothing I see even remotely illegal about it...A bit over priced for what it is, unless you have a registered AK, no reason to waste $25 on it...but relax...no different than the regular M16 sears which range from free-$10 all over the place...
Hell even the "shadey" "pre81 AR DIAS's" are perfectly legal if you don't have an AR, and this isn't even in that "shadey" catagory...Don't know why you'd want one, but if you want to waste your $$$ on it, go ahead, no one will be kicking in your door (unless you have done something else)...
