This is my greatest invention yet.Its a pen gun version of a sniper rifle. It shoots very very far up to 45 ft. and is able to pierce shoe boxes very deep. I first made this when i was at my cousin's house as a prototype while we were testing out various pen guns with his friend. I have some blueprints that I'll post later on with this instructable.
To make this pen gun you will need a "pentel wow" click pen(or anything similar), a crayola twistables tube, the end of a click pen(green) or something similar, black peg with nail in it, a thin transparent pen tube, a fat pen tube, 4 rubber bands(3 thick and 1 thin), a paper clip, and duct tape.
Step 2: The barrel
Put the skinnier end of the crayola twistables tube into the "pentel wow" pen and tape it together. This will become your barrel.
Step 3: The body and trigger
Now drill a hole near the end of the transparent tube.Insert it half way and tape it to the fat pen tube. Now insert the black peg with the nail in it in the hole of the transparent tube.Tie it with the thin rubber band.This will become your trigger.
Step 4: The body(cont.)
Now tape the whole thing to the barrel.
Step 5: The scope
Now drill a hole on the green thing. Next tape it 5 1/2 in from the tip of the barrel.
Step 6: Holding on
Now put the 3 thick rubber bands as shown.
Step 7: The stock
As every sniper rifle, this one also has a stock.To make the stock tale the paper clip and bend it 90 degrees.You can straighten the clip with pliers first(optional).then bend it 60 degrees.It has to look like a triangular stock..
Step 8: Attatching the stock
Now all you have to do is tape the stock to rhe end of the transparent tube.
Step 9: Finish
when youi're done simply cock the rubber bands back and attach them to the nail.Then simply pull the trigger and watch it shoot.This is a weapon not a toy so don't let little kids play with the as it is extremely powerful and they can hurt themselves.Please note that im not responsible for any injuries or deaths.You can use a medium or large sized mauler for the bipod(optional).
