when I was disassembling the gun and taking pictures of it I forgot to make some important pictures for the instructions,my bad, in my oppinion it's a real cool gun, I invented the mechanism myself and the gun itself looks really badass. to load the gun you just put the rubberband's on top of the barrel and all the way back to the wheel and then cock the wheel back for the next rubber band. if it is really needed i will upload some more detailed instructions and/or video
Step 1: Step: 1 Mechanism and Internals
it hard to see how it al works and I forgot to make a picture of the side plates so i hope you can figure out how it works. :)
Step 2: Step: 2, Grip
not much to say about this.
Step 3: Step: 3, Barrels
in the next step you might be able to see where to put the barrels.
Step 4: Step: 4, Pump
hope this is enough.
