you might could find one on the internet somewhere just do a search theres bound to be someone who sells them on there but i doubt its legal to use on anything unless you own a zoo or something and i know its illegal here in florida to hunt with one. and useing it on people is a big no no so you probably do have to have a reason or permit or something for one like a regular gun because it can be used for wrong to i mean whats to keep you from poisioning people getting the kids to settle down or useing it to drug and rape women and all
