Introduction: Tiny, True Trigger, Mag Fed K'nex Gun -El Mosquito

Picture of Tiny, True Trigger, Mag Fed K'nex Gun -El Mosquito

OK well I decided I wanted to see if I could make the smallest truegger, mag fed gun yet. This is what I ended up with. I decided to give it a Spanish name just for the heck of it and because I was tired of giving a gun an acronym for what it is. It loads about 5 green rods ( I think) I wouldn't really use it as a war weapon except as a pocket gun of desperation. It is pretty fun to play with and makes for a great knex gun to bring to school in your pocket.

P.S. I don't really know why I'm posting this seeing how it can be built from one picture for the most part =P

Step 1: Handle/ Magazine

Picture of Handle/ Magazine

It's a basic handle magazine for green rods. The idea of extending it with oranges is credited to oompa loompa. You could probably shorten the handle further but it would make it rather hard to wield and leave the amount of ammo you can store very minimal.

1-3. All very easy. Make the first two and attach like so.

That wasn't so bad huh? Moving on.

Step 2: Top of the Gun

Basically this makes up the receiver, barrel, and pretty much what holds everything together.

1. This is optional but I would add this white rod to prevent the back side of the magazine front bending while cocking.
2. Gather the pieces and build what is seen
3. Attach to the magazine by green rods...
4. Then add the white rods.

Alright still pretty easy? Let's continue.

Step 3: Finishing Up

Picture of Finishing Up

Alright we're going to finish up all of the main parts for the gun itself before we figure out how to fire it.

1-2. Pieces you'll need. Add the two parts together. You might be able to use a normal orange although I'm not sure how well it will work. I just used this piece from the TDSS
3. Clip the joint onto a green rod in this spot. You can also use a dark grey instead of the ball joint but you'll have to hold the green rod in for awhile and rely on a rubber band to hold it there.
4. Grab these pieces and for the trigger (and a rubber band)
5. Take one of the oranges with a black hand and connect it to white rod like this. Pay attention as it's not connected in a normal fashion.
6. Take the other and connect it on the other side.
7. Take the actually trigger construction and clip it into the end of the oranges.
8. This is the hardest step...grab and connect these two pieces.
9. Add that here
10. And finally finish up by adding a rubber band like so.

You have now finished the main part of the gun. On to firing.

Step 4: Firing

Picture of Firing

Basic firing mechanism. You can use any pin size you want. I find tan the best as grey is just too long for a gun this size but yellow makes it pretty weak although you could use yellow if you're trying to make it fit in your pocket better.

1. Here's the firing pin. Pretty basic. You'll use the green rod for a ram lock later.
2. Put the pin in the back o the gun.
3. Insert that green rod. It will help hold the ram in place and also acts as a ram lock, stopping you from pulling the pin out of the gun when cocking.
4. This is where I put the pin rubber band but you may find a better spot. Try to get it as close to the pin as possible without touching. It will slip off every once in awhile so check it and readjust it as needed.
5. Grab up to 5 (maybe more I never tested it beyond two) green rods and make a mag pusher. This is what I use but free to make something different.
6. Insert the ammo into the mag
7. Add the mag pusher. Make sure the rods are straight in the magazine.
8. And now a picture of my baby sister for the heck of it.

Alright now just pull the pin back until you can't anymore (meaning the ram lock is working...) and then let it forward gently until the ammo is in position behind the trigger. This may be tricky as it's hard to hold and takes quite a bit of pressure but pull the trigger and there you have it. Thanks for building!

My trigger isn't working

How do you use the trigger it's not working

knexbug (author)2014-02-20

Have you had any trouble from DJ radio? I notice he has something bad to say about everything

knexbug (author)2014-02-20

thanks my last name is duncan and i'm from leeds england

knexbug (author)2013-09-16

this has got to be the best small multi shot gun ever despite the small trigger

TheDunkis (author)knexbug2013-09-16

Eh, debatable. Depends on what you want exactly. If tininess matters more, then the Nano gun a few posts below is better. If you want performance in a compact repeater, my mini-TDS and the OKP did just fine. This was only for the sake of making what was once the smallest but now no longer is.

knexbug (author)TheDunkis2014-02-20

Juging by what you said on your Bio i hope you wont mind if i ask how old you are, what is your real name and where you are from. Dont feel you have to reply if you dont want to , i was just interested. PS i'll check out your tds and okp

TheDunkis (author)knexbug2014-02-20

20, Duncan, and Minnesota.

knexbug (author)TheDunkis2013-09-17

well, i am pretty new to instructables and i made this gun about a year ago so i guess it has been outdated by now. But i found it to be quite accurate, powerful and reliable.

knexbug (author)2014-02-15

DO youdo nerf as well as knex ???

knexbug (author)2014-02-15

oh dont be so modest dunkis your guns are SUPER COOL and dont let ANYONE tell you different!!!!!!!!!!!!!!!!!!!

Annix15 (author)2011-12-07

sorry man, make a small gun again with a better trigger, and i will make it.

knexbug (author)Annix152013-09-17

i think the trigger was fine

TheDunkis (author)Annix152011-12-07

Oh no, I am forever crushed. Nah, this gun is entirely obsolete. I just don't remove my 'ibles so that people can still see what I once made. I long ago have since made my Nano gun. Thanks for reminding me, too. I've yet to show this off to my friends.

Annix15 (author)TheDunkis2011-12-08

no problem

Annix15 (author)2011-12-07

yea, this is ridiculous, The rod won't pull back from the trigger, can't even pull the trigger cause i have to use the blue rod to pull it down. 3*

NINJAboyofwisdom (author)2010-02-18

 I want my 2 minutes back!

ashchetm (author)2009-09-24

lol I brought mykhalo's sidearm to school and everone on the bus was like "JON DOE has A GUN!!!!!!!!!!!!!!" it was havoc, i had to take it apart and hide the rubberbands in my sock.... my bus driver was like "i dont want another colmbine" ya it was not a bright idea to bring a knex gun to school.... PS: lol i bet somebody thinks my name is jon doe

aleceatsfood (author)ashchetm2010-12-24

lol now THATs funny btw i kinda though ur name was Jon Doe untill i finished reading

DJ Radio (author)ashchetm2009-11-09

I made a paper gun in class, and this guy comes in and said "You forgot your gun", and the whole class was erupting until the guy said it was made out of paper and didn't shoot. 

ThisChessPlayer (author)DJ Radio2010-08-12

i've made a 3 piece gun. it's easy to take apart. so when someone was like **** he has a gun!!!!!!!! i took it apart and i'm like ? and the class was like ? so the teacher thought it was a joke.

aleceatsfood (author)2010-12-24

i must sayyy........... I LIKE IT!!! ill build it later

ArceusX0 (author)2010-10-22

well dunkis, ur still genious!

Nothing2it (author)2010-10-19

Worst gun ever!!! Fix the trigger, it keeps jamming!! until then, .05 stars!!!

shieldsam (author)2010-10-16


the rod is impossible to pull back, the trigger blocks it

ArceusX0 (author)2010-08-30

n00bs! This gun is AWSOME!!!!!!!! It gets GREAT range! Why the flip do u guys say this dude cant make a gun? El mosquito is better than ur gunz!!!!!!!!!

TheDunkis (author)ArceusX02010-08-31

Well the whole purpose behind this gun was to be the smallest effective repeater and it was beat only so long after posting.With the nano gun being smaller and other side arms being more effective, this thing pretty much became obsolete.

moishyb (author)2010-08-27

Does it matter with side it goes on?

Fred the evil puppet (author)2010-08-21

look for big z's "the tick"

Look for my Nano gun.

K-Dawg (author)2009-07-10

cause i think I made smaller

TheDunkis (author)K-Dawg2009-07-10

1. That isn't smaller. And basically it's just a modified OKP. Did you build this gun and compare? 2. v Nope v

moishyb (author)TheDunkis2010-08-16

How did you make that?

TheDunkis (author)moishyb2010-08-16

Exactly how it's shown. Someone posted instructions I think though although slightly modified if you search up nano gun.

lugnut004 (author)TheDunkis2010-06-21

i just want to ask what the hell is a okp can u tell me

I made a gun HALF the size of yours now. It's so ridiciously small. It shoots BB's from a mag. I don't think anyone can beat it.

It's no longer a K'nex gun now is it? Nice idea though. I've made one about as small that still used green rods but it worked horribly.

Actually this one also does work horribly. I think it's not good to make guns THAT small.

Exactly. That's why I like the nanogun as it is the smallest gun that actually works quite well.

Millawi Legend (author)TheDunkis2009-07-26

Hey can i post this gun?

TheDunkis (author)Millawi Legend2009-07-26

Uh...I guess. Not really worth posting being as easy as it is but whatever. Just make sure you give me credit obviously.

Millawi Legend (author)TheDunkis2009-07-26

Yeah il post because some people can figure it out but i will give you 100% credit

Cant figure it out i meant.

altair ibn la ahad (author)2010-07-21

mine works dorks

destroyo5457 (author)2010-07-08

how come my trigger isn't working??

rust (author)2010-05-21

Hey Dunkis! I loved the platform of this gun, so I went ahead and made a full-sized/compact version of it! I present to you; The modded-to-all-hell "El Mosquito"!

-Improved trigger system with a nearly FLAWLESS mechanism and more comfortable, less stiff trigger
-Large, 18+ shot magazine/handle, perfect size for grip!
-Extended barrel
-Improved ramrod with grip
-stock/butt for improved accuracy
And, best of all, because of the low-piece platform, it is very beginner-friendly and easy to use!
(sorry for the low-quality picture, couldn't find my camera lol)

This would be my first gun posted onto the site, what do you guys think?

stubbopolis (author)rust2010-06-21

cool, looks realistic
