my brother and i just threw this thing together today. the video explains most of it. the battery pack is temporary and will be replaced with a few trustfires very soon. we're also thinking about using some leather or something to pretty up and smooth out the final product.(Firing Video) http://www.youtube.com/watch?v=c5ER0hQS6ss&feature=youtu.be
we're also working on a swarmshot (longshot/swarmfire) and a full sized swarmpede which should be done pretty soon. oh and probably a right handed wrist cannon.
heres a pic of the gun, swarmpede (speedswarm/stampede), and my new blowgun.
