Introduction: How to Make a Pen Gun

I will show you how to create a pen gun out of the pen shown and a piece of paper. You can buy the pen a Wall Mart, Target, Staples, Office Depot, and tons of other places. This pen is VERY common. For the ammo you can shoot almost every thing that fits in the barrel although I prefer airsoft BBs.

Step 1: Know the Pen Parts

To split the halves just unscrew the pen in the middle.The first picture is a diagram of the pen parts. The second picture shows how to get the 2 parts at the back out by pushing it out with the ink. The third picture shows how to get the spring out by pushing the edge of the spring with a mechanical pencil with a inch of lead poking out.

Step 2: Making the Wadding

The wadding is a compacted piece of paper that keeps the pen from shooting itself apart. To make wadding...

1.Tear a small piece of paper from lined paper(lined paper is thinner than normal white paper)
2.Crumple it up and put it in the clear end of the back half.
3.Put the flat end of the ink in through the colored end and press down until the small sheet is compact then push it out. Save it for later.

Step 3: Asembling the Gun

To put the gun together you need to do 5 things.

1.Put in the back button
2.Stretch the spring
3.Put in the spring
4.Put in the piston like object WITH THE NARROWER END DOWN!!!
5.Push the wadding in with the ink.

Step 4: Loading and Firing

Loading

1.Cock the gun by pressing the wadding as far down as it goes. When you remove the ink the wadding should stay down.
2.Drop your ammo down the barrel.
Note:Depending on how well you made your wadding you may have to replace the wadding every 3-10 shots.

Firing

1.Optional: Slide the front half on the clip on the back half for a grip
2.Hold as shown.Press the back button to shoot.

I have done a similar thing except you only need a pen

i wanna make my own gun. but how ?????
do any body give some idia.

I am hopeless as to what to use as ammo.

i was going to make one the same but you already made it

if you put the top on, it kinda looks like a spy wepoan.

now i can't reload! aaaaaaaaaaaaaaaaaaaaaaaaaah!

the paper pops up every time you shoot, so i keep having to push the paper down. i don't know what to do because the paper wad is irremovable. :(

If you do the optional grip step under Firing you can but your ammo in the front half for storage!

So...This is like a mini BB musket?

This so awesome. :D Everyone I know has this exact pen. I have an idea, a pen gun army!

That would be epic! We could overpower almost any non-government organization with these.

As long as they have no guns, knives, pens, or pointy objects.

unless we fire small, pointy objects with these

your gonna go pen vs gun?!?!?

Duh! It's the only possible way to feel exactly likke Chucl Norris while not feeling like him at all!

Any NON-government organization. I sharpened the tip of the pen cartridge and it stuck into a wall. It was really hard to get out.
