Interesting...Watched the video, so let me explain the quick dirty of it for those who may not catch the video.
Its basically an arrow tip for a bow, which threads on. The arrow head is basically a single-shot firearm (lack of a better definition) which is reloadable with either a 38 special or 357 mag cartridge. When the arrow head contacts a target, the energy in the arrow shaft causes the round to fire.
Things the video did not mention:
1. Is the device rifled, or smooth bore
2. No legal information on possession and purchase.
3. No talk about BATF approval.
Basically, from what I can see from the video, its like a zip gun, except for the energy in the arrow shaft is what fires the round.
With the above said, I plan on staying away from it, but will be watching to see how the BATF boys react to it.
One issue I see from the start is about hunting regs....Will this fit in to bow or gun season?
Question is though... Is it a firearm, or "other weapon" etc line of thought, or is it none of those things, and legal without any paperwork. I'm going to think on it and research a bit.
