I have had this bow for a while now, and I will not be posting instructions for it as I am using parts from it to make my emplacement gun bigger. It shouldn't be too hard to make from the pictures. Sorry about the shoddy pictures, when I post my emplacement gun I will use my digital camera.
My new and comfy handle, with anchor points for a monopod
Sturdy and robust design
Fires 45-60 feet
A hybrid system; the bow flexes, providing some power as well as the rubber bands.
