Quoting Chris Kweon
wait does that really shoots???
it doesn't shoot any bricks or rubber bands if thats what you mean, but if your asking if it would actually shoot shot shells well, I might be able to make a working mechanism but I doubt the plastic pricks could hold the pressure from the released gases, it would probably just explode the bricks would melt and there would be molten legos all over me and it would burn me and I would die, I hope that answers your question :)
