How to build a pen gun

This is how to make a far shooting pen gun that you need only a pen to make.

Step 1: The Pen

You will need a pen that is similar to this one.

Step 2: Disassembling the Pen

First off disassemble the pen into the three main parts by untwisting it at the middle.

Step 3: Getting Out the Little Pieces

Get the two plastic pieces out of the back of the pen by shoving the ink cartridge into the back end of it. To get the spring out of the front part of the pen bang it on a hard surface with the big opening facing down.

Step 4: Loading the Gun

To load the gun insert the small pieces into the back part of the pen in the order shown.

Step 5: Cocking the Gun

To cock the gun insert the ink cartridge into the opening and push the pieces backwards and then remove the ink cartridge.

Step 6: Shooting the Gun

To shoot the gun push on the button that you press to use the pen and it will fire.

How to build a pen gun

Question 2 years ago

Didn’t work for me. Pen I’m using is a Pilot G-2. You said the pen would cock as you pushed the ink cartrige, which isn’t happening. Help?

Answer 6 months ago

I used a pilot G-2 07 and it worked for me. Maybe it’s because you didn’t notice that the bolt clicked in, or maybe because you didn’t push hard enough? Just remember that if you want it to shoot far, put the bolt in the way it is in the picture. But if you want it to penetrate things, you have to put it in the other way. Hope this helps.

How to build a pen gun

Super easy pen gun. All that you need is a Pilot G2 pen or similar pen. (They have easy access to the spring.)

Step 1: Get a Pilot G2 Pen

Come on people, this step takes five seconds. If you don’t have one, you can find them on the ground at school. Once you have obtained this then you can begin with the rest of the steps

Step 2: Disassembly

Disassemble the pen (don’t bother with the small white piece at the end of the pen near the clip) That’s all you need for this step.

Step 3: Put the Spring on the Writing End of the Pen

Put the spring on the pen.

Step 4: Put the Writing Part Into the "Chamber"

Shove the pen in there- just not too hard. You don’t want it in there too hard.

Step 5: Put the Cap Back on the Pen

Put the cap back on- just barely, if you bump it- it will fall off. Then for firing just click the pen and it should get at least 10 – 20 feet depending on how hard you press it. For variation you might want to glue the cap to the end of the writing part.

How to build a pen gun

Step 1: Equipment and Materials

-paper clip(forgot in image

– hack saw or scissors

Step 2: Step 1

Disassemble the pen so that you only have the tube.

1. Remove the yellow tip from the blue connector thing.(the yellow tip is connected to the Ink tube.)
2. Remove the blue connector
3. Remove end cap( i used a screwed driver)

Step 3: Step 2

1. Cut the blue connector at the point where the scissors are placed in the image.
2. sand and file the surfaces that has been cut
3. Cut the bottom part of the blue connector just below the bic logo. Afterwards file and sand it. You will only need the part without the bic logo.
4. hot glue the blue connector bit that can fit inside the pen tube.( push it in so the whole thing is inside the tube. just at one end. The picture next will display what i mean.)

Step 4: Step 3

1. dig a hole into the tube as shown.
2. Start sinking the knife into the pen tube and sliding it forwards to create a long slot.
3. start carving the edges and filing it so it becomes wider. 3 mm wide and length varies on how many springs the pen gun contains.
4. sand edges so it is smooth and remove unneccessary pieces of plastic hanging on the edges.

Step 5: Step 4:

1. Connect the blue connector that was cut earlier, and connect it to the yellow tip.
2. Pull the yellow tip from the inktube.
3. Hot glue it back together so it has a tighter and stickier fit. Remove any dispensable glue.
4. Put the inktube inside the pen tube. On the inktube, just before it reaches the top of the slot that was cut out, create a small hole from a thumb tack or something, a whole where one end of a paperclip can fit in it.
5. Get a paperclip and cut it so its about 4-3 cm. Then, bend it so it is about a right angle side of the right angle smaller than the other.

Step 6: Step 5

1. While having your inktube inside the pen tube, insert your springs.
2. If your springs do not reach higher than the hole u made on the inktube for the paperclip, simply insert the smaller side of the right angled paperclip into the inktube.
If your springs are height is beyond the hole that was made on the inktube, simply take a skewer and push the springs down so its under the hole(compressing the springs)and then insert your paperclip.
3.pull the yellow tip so that the springs fully compress. Mark the point on the pen where the ink tube can not possibly go down any further. Mark that point with a texta or permanent marker. Cut the hole like in the picture below.

Step 7: Homemade Ammo

If you do not possess BB’s, you can create something similar by making solder balls or balls out of glue(produced by the hot glue gun).

Step 8: Firing

Pull the paper clip down and twist it to the side hole at the point where the springs are fully compressed. Once done that, flick the paperclip out of the hole and it should fly up shooting anything inside the pen gun.

While English playwright Edward Bulwer-Lytton in 1839 probably meant something different when he coined the well-traveled phrase “the pen is mightier than the sword,” that phrase defines the Stinger pengun.

Penguns 101

Since the 19th century, firearms have been disguised to hide inside of innocent items such as canes, lighters, belt buckles, clothing and even jewelry. By the 1920s, the first pen guns, fashioned to the same general size as fountain pens but capable of firing a single handgun round, typically a low powered .22, were fashioned. These guns were used by spies on both sides of occupied Europe in WWII and then later in the Cold War between East and West. James Bond even sported a pen gun in Never Say Never Again but these guns could get you 10 years or more if they aren’t registered as an AOW (Any Other Weapon) with the ATF under the National Firearms Act (NFA). This however does not keep them out of the hands of criminals around the world.

The design of the Stinger

Unlike the true penguins mentioned above, the Stinger was NFA-friendly and even ATF-approved. Mechanically incapable of firing while in its ‘I’m a pen’ mode, the firearm had to be transformed into a pistol by pulling and pivoting the cylinder on a hinged joint. This gave gun a readily identified barrel and grip. A small trigger without a guard popped out when the gun was in this mode. To fire you simply pointed the muzzle end in the general direction of the target (there are no sights) and pushed upward on the trigger to fire. Since the Stinger operates in this method, and doesn’t fire while in ‘pen mode,’ the ATF blessed it with the title handgun and not an NFA-regulated AOW device. Hence, it is a cash and carry weapon with a normal transfer and not a Form 4 nightmare with tax stamps, CLEO signatures, etc.

Length of the Stinger when in pen mode is just under 6-inches. This is the same as a normal Bic-style disposable pen, but is closer to the thickness of a sharpie-style marker. At 5-ounces, it was heavy for a pen, but still less than an 8-ounce single-shot Butler derringer. The case, 2-inch barrel, and internal parts are all made of steel. No aluminum, pot metal, or plastics -err I mean polymers were used in the construction. This tends to make the Stinger look more like a tire-pressure gauge-gun than a pen-gun but that is not nearly as snazzy a sell. A neat little metal collar behind the barrel twists around to form a crude but positive active safety device.

The downside of the firearm of course, is its limited practicality. While it could be carried in a shirt pocket conceivably as a self-defense firearm, it would take 2-3 seconds to deploy in even the most optimistic of circumstances. With no sights, it was a point-blank weapon. The fact that it had to be disassembled to reload the single round meant that in almost any circumstance it would be a one-shot wonder.


Bob Braverman filed for a patent in 1990 and the next year started selling under the American Derringer Company of Waco, Texas the Model 2 Pengun. Bob soon broke with ADC and as the RJ Braverman Corporation in Meredith, New Hampshire, began manufacture of the same NFA-compliant pistol, now renamed the Stinger. Between 1991-1997, the company produced the neat little pistol in 22LR, .22WMR, .25ACP, .32 ACP and .380, with the rim fires being the most common. The company also built a folding revolver that bears a visual similarity to the Chiappa firearms Rhino of today.

For about a half dozen years the gun was out of production but in 2002 a new firm, still with some ties to the design’s inventor, Bob Braverman, formed as the Stinger Manufacturing Company in Michigan. However, they folded for good in 2004. It is not known how many Stingers were made under the three different companies, but it certainly was not very many.

Collectability today

The Braverman Stinger has been out of production for almost a decade now. Back in the 1990s when they were new, it was not uncommon to pick up one in the box for a $100 bill. Since the stock of new firearms has shrunk and many collectors are hanging on to their examples, prices have increased dramatically. They have a growing legion of niche collectors who celebrate the well-constructed little handguns. Today rimfire models typically bring over $500 while the .32 and .380 versions are sometimes seen for almost twice that amount.

I will show you how to make a pen gun using a few simple supplies listed below. These things are very powerful and really fun to use! They will pierce boxes, papers and more!


1. Rubber Band – The thicker the better, normal length works.
2. Ball Point Pen – The ones with the screw off tops are best.
3. Heavy Duty Clip – Not a paper clip, the black ones used to hold large amounts of papers.
4. Scissors – Depending on weather or not you have a screw off pen.


1. Take out the inside part of the pen holding the ink. Don't throw it out, it will be your "ammo"

2. Unscrew/Cut off both ends of the pen so the part that holds the ink can easily slide through. The less restistance there is the faster and more accurate it will be.

3. Place the part that holds the ink inside the pen (the part you write with facing the way it will exit, doesnt matter which way it exists, you decide.)

4. Place the elastic on top of the pen (the outside part, not the ink part) have one end of the elastic on where the pen will exits. Once you have done that secure the elastic with the heavy duty black clip. Be sure not to block the exist path of the ink part.

5. Grab the ink part and the elastic, pinch both together, pull back and fire!

I am not responsible for ANYTHING you do with this pen, neither is this site.

That BB guns are famous is an understatement. The National Rifle Association of America did a study. A body in charge of sport shooting that involves the use of rifles and pistols found that over the past 5 years, there has been an increase in Bebe guns’ purchase by an average of 12 percent. This was 4 percent more than the metal gun sales, which averaged at 8percent. If you’re looking for a new one then check out Guns & Safety Reviews.

Why the sudden increase in Bebe gun purchases, you ask. Below are some of the reasons;

  • They are cheaper – bebe guns are more affordable compare to their steel counterparts. It is also cheaper to buy their ammunition ( which are mostly metal Bbs ). A person firing one round of real bullets will spend more than one who fires one round of metal Bbs.
  • Lesser accidents – given the nature of their material . According to guns and safety reviews, the chances of a Bebe gun killing or injuring someone is about 4%.

In this article, you will learn how to make a bebe gun out of a pen, using eight easy to follow steps.

Materials you will need

 A knife or scissors

Step 1

Strip the pen of all its parts (thrust device, spring, plunge). Only the barrel part should remain. The barrel will be used as the body of the gun.

Step 2

Using your knife or scissors. Drill a hole in the barrel. Try to ensure the hole is sizeable enough to allow the airsoft bbs to pass through. Place the hole at about a quarter-inch from the barrels center point.

Step 3

Pull out the ink chamber from one of the pens. Place your hand in the middle of the ink chamber; measure a quarter an inch from the middle point. Using your scissors, cut a quarter part off. Please note that it’s advisable to use an empty ink chamber. This will prevent ink from spilling on you.

Step 4

Glue the quarter-cut part of the ink chamber in the cap. This will act as the guns propeller. You may now place it in the barrel.

Step 5

Place the attached ink chamber into the barrel .Then tie the rubber bands onto the barrel at the end of the cap.

Step 6

Pull the cap behind and release it. This ensures that it moves freely and that the rubber bands are firmly held onto it and the barrel.

Step 7

Take another pen, empty it of all its components leaving only the barrel. You can then close one end of the barrel with duck tape on the open end in a few airsoft BBS. Then attach the barrel with the airsoft bbs onto the other one with a cap.

Check to ensure the barrel’s open part is directly onto the hole you made on the other barrel.

Step 8

You can now tap the barrel containing the bbs, and once it falls into the other barrel, pull back the cap and release it to fire. Congratulations, you have made your own pen, Bebe gun.

Ian from Forgotten Weapons Analyzes a Unique Single-Shot Pistol That’s Disguised as a Pen

Written by Patrick McCarthy on March 3, 2017

They say the pen is mightier than the sword, but everyone knows that’s not a literal statement. In this case, however, it might be. The “pen” seen here is actually a single-shot pistol, which folds open like a Transformers toy to reveal a tiny trigger. It’s called the Braverman Stinger, and it was produced by R.J. Braverman from approximately 1993 to 1997.

Despite the obscurity of this miniature firearm, its mechanism is interesting to say the least. It was supposedly designed with this folding mechanism in order to avoid being categorized as an AOW (“any other weapon”) under the National Firearms Act (NFA). By folding open at an angle before it can be fired, the ATF ruled that it resembled an actual firearm enough to be classified as an ordinary pistol. This makes it much easier to obtain than other disguised weapons, like cane guns — or it would, if more of these Braverman Stinger guns ever made it to the market before the parent company went out of business.

How to build a pen gun

The Braverman Stinger was available in several calibers. .22 LR, .22 Magnum, .25 ACP, .32 ACP, and .380 ACP. There was even a rare factory gold-plated model for the James Bond fans. Ian of the YouTube channel Forgotten Weapons got his hands on a .25 caliber model for the video below, and discusses the gun’s interesting history and quirks. True to form, he also disassembles the gun and shows its functionality.

Unfortunately, the pen gun above was up for auction, so it couldn’t be fired. Based on other YouTube videos, they do in fact fire, but only about as well as you’d expect from a bent tube without a proper pistol grip, sights, or trigger. So, what do you think of this non-NFA pen gun? Is it a cool real-life spy gadget, or something that doesn’t have much use beyond the silver screen?

You know that awful beard trimmer your Aunt got you for Christmas, that you never use, because not only does it less cut the hair more rip it from you face – well therein lies the main part of your good old prison tattoo gun: The Motor.

In years gone by you’d use a Walkman motor, but since they are no longer made (and honestly, being seen wearing a Walkman cassette player in a modern prison is going to get you big time humiliated) the beard trimmer motor is the one you want.

On top of that you’re going to need a Bic Biro, or Sharpie – this will make the chamber, and the adjustable finger rest, some tape, a battery, and you’re pretty much done.

Pretty much. But what about the needle? And this is the bit that makes me feel weak, I’m not great with needles at the best of times, and the prison tattoo gun is not the best of times, in terms of the needle at least – it’s the worst of times. The needle is made from the spring out of a lighter. Yup. That coiled compression spring is heated over a candle, stretched and straightened out, and that there is your needle. Attach a piece of sandpaper to the motor pre-assembly to sharpen the ‘needle’, strap a battery on with some tape, string, anything – and you’re good to go. Ouch.

A selection of Prison Tattoo Guns – while clearly remarkably resourceful, not for the squeamish.

Ask anyone who’s done any time in prison and the overriding response is boredom. it doesn’t fit the narrative but time drags when you can’t distract yourself, which is what the rest of us – those on the outside – spend most of our hard earned money on – doing things. So while these tattoo guns are without doubt crude, almost barbaric, getting and doing tattoos takes time, and as such they remain popular – although forbidden in prisons across the world.

And they produce remarkable works of art – some of the prison tattoos, with all their encrypted meanings, and for all the lack of ‘actual’ tattoo kit, are some of the most impressive tattoos around. They lack the clarity of others, but they have their own aesthetic – which some people on the outside actually try and recreate.

Here’s some prison tattoos, almost certainly made with the type of gun I have explained. And take into account, the ‘ink’ is made by putting a wick in a tin of hair grease and collecting the soot on a piece of card. Yeah, that, pushed into your skin with a lighter spring.

So where am I going with all this? Well, as a lock picker I have always thought if ever I got locked up for life (and I hope this rather flippant comment never comes back to haunt me as some accidental prediction) I would like to think I would plan some kind of escape, I would earn my place in the escape team based on my lock picking abilities. (Come on! Cut me some slack – we all have our fantasies!) I would be able to somehow make some picks, whether for handcuffs, leg irons, a door or two, a padlock on some kit – anything – I would at least like to think, given a couple of years in a cell, I’d have time – and the resourcefulness to make some kind of pick or bypass tool to get me out. Even though modern prisons are all electric locks and automated doors, lol. Let me have my dreams!

Now, let’s be honest. This is based on watching far too many movies and not having been locked up for life. It’s kind of immature, and unrealistic. But plenty of people have bodged picks out of items they had laying around. If you can make a tattoo gun, you can make some picks!

And tattoo guns aren’t the only things they make. Check out this selection of prison handiwork.

A saw – quite nice too!

A shotgun. A SHOTGUN.

If you can make a shotgun in prison you can make some picks with stuff around the house. I mean, people have been making very nice lock picks from hacksaw blades for years. And remember – before the internet it was hard to find lock picks, and what do you think people did to get lock picks? Most people made them – that was your option. Where do you think most of the designs we use today come from? People were making their own lock picks at home for decades – long before there were professional pick manufacturers got hold of the designs.

Here’s a selection of crude – but arguably effective – homebrew lock picks.

Classic hacksaw blade lock picks.

Incredible ingenuity – handles here made from a fork handle, circuit boards, a pin vice, and a pen. Wouldn’t be out of place in the prison tools photos.

Incredible set here, made entirely from hacksaw blades, the entire kit folds up (see pic bottom left) and slips into the case.

A hook, half diamond, king and queen rake and a B rake with handles made from pin-vices.

How things used to be. Luckily today we don’t need to glue a hacksaw blade to a spoon handle, just as we don’t need to burn off hair grease to get soot for a tattoo. Having been around pre-internet (yes, I am ancient) I remember the absolute lack of not only lock picks, but everything! Wow, I have no idea how we got anything now I think about it.

But I also remember the early internet, the many, many shops selling lock picks, a rough selection, mainly Chinese imports, terrible customer service, awful websites, no technical assistance, nothing. Thank The Lord that today we have the beautiful selection of picks we have. Wonderful and ingenious designs, expertly packed and professionally conceived by experts who pick locks, and who love lock picking.
