About: I paint, write music, and used to build knex guns. I have a Bachelor's Degree in Studio Art. - updated 5/7/2014
Semi-Auto Pich Fire Rifle: Uses the firing system from this gun, but instead of pulling a trigger to fire, the operator pushes the gun into their shoulder, which forces the stock forward and fires the gun. Could probably get 30+ feet with gray connectors. -by Oblivitus

I'm busy with another gun right now, but this is a really exciting new idea, and it's fairly simple. Would someone please build it?
