Picture of 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

Picture of 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.

I am hopeless as to what to use as ammo.
picosoaaron3 years ago
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

Jaredicus jeiy3 years ago
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.

Hello! I have problem. When I fire my pen (I never thought I'll say this :) ) everything inside flies out. Can you tell what am I doing wrong?
bjb98 theimler3 years ago
put your finger over the edge of the back section and just let the ink cartridge shoot out. Forget the wadding.
sk8er82 (author)  theimler4 years ago
wen u make the wadding, use a bigger piece of paper, that should help :D
Squibb theimler4 years ago
What you can do is cut the very end of the pen grip holder thingey and screw it into the end of the barrel with the eraser of a pencil. (Stick the threaded plastic thing on the eraser part of the pencil.) This should fix your problem.
theimler Squibb4 years ago
Thank you! it worked, I had a little trouble with the cutting, but I solved it, so now it works well! thank you, again :)

Why does my pen gun shoot itself apart every time I shoot wit??
elemastur3 years ago
the wadding didn't work on mine, so i superglued a piece from another pen about .8 centimeters in diameter to the inside of the barrel of the pen, and added grip. it works better than the wadding, and it catches the mechanism inside a lot better. is there another way to load it, easier than using the pen cartridge? by the way, this is genius!
skaterboy114 years ago
this is awsome :D
skaterboy114 years ago
I havent made one yet but im going to.

Pretty sweet, but mine will only shoot like 5-6 feet, is that normal or can it go farther?
pbmillar124 years ago
I'm looking forward to using this is science class when i get bored. Thanks!
why do you need the wadding?
sk8er82 (author)  Paintballer984 years ago
so that the pen doesn't shoot itself apart.
I know but what is the point of putting it in, it works just fine without it
sk8er82 (author)  Paintballer984 years ago
well after a while of using it, the plastic ridge will wear out a bit, and it wont work. So by putting the wadding there, it makes it last much, much, much longer. I haven't had a pen with wadding wear out yet.

I once made this, but
1. I suggest emptying the pen before make the "rifle" otherwise ink spills from the back airhole (i had to throw away mine due to this :'( )
2. I suggest use toothpicks for ammos (if you want to just shoot to a target, otherwise use BB's)

The only problem I've had is keeping the wadding from popping back up automatically. Any help?
sk8er82 (author)  Jobolonian4 years ago
try using more paper for the wadding or squishing it down more... or both! good luck :D
