This is an airsoft gun I made in about 10 minutes.
Step 1: Get Your Supplies
What you'll need:
-2 or 3 pens
-scizzors (you can use a knife)
Step 2: Prepare the Main Barrel
Strip off everything on the pen except the main barrel part. (keep the rest of it near you).
Make a hole in the barrel about 1/4 inch behind the center point. (Make the hole large enough that you can easily fit the BBs through.
Step 4: Make the Firing Mechanism.
Take a clear bic pen(pic 1) and take the ink part out of the tube(pic 2). Now take the long plastic thing off the ink tube(pic 3) and cut about a 1/2 inch off it(pic 4). Now place that part back on the ink tube. (keep the main tube near you).
Step 5: Makiing the Main Part.
Put the firing mechanism it the tube you cut the hole in (pic 1). I added duct tape to make it look cooler (pic 2). Now ad a rubber band to the outside of the barrel and duct tape it to the firing mechanism and the barrel (pic 3).
Step 6: Making the Mag Holder
To make the mag holder take the cap of one of the pens, cut the tip off (pic 2) and attatch it over the BB feeding hole in the barrel (pic 1)
Step 7: Making the Mag.
Take the main tube of a pen, make sure the end cap is still on it, and pour the BBs in. now either take another end cap and place it on the other side or I used the thing I ripped off the tip. I also made an extra large mag by taping two tubes together.
Step 8: Firing.
To fire, pull back the mechanism and release! the BB should shoot out and you should have yourself a pen airsoft gun!
