Introduction: Insight: a Mini Tubular Magazine K'nex Pistol

Picture of Insight: a Mini Tubular Magazine K'nex Pistol

Insight is a tiny, compact pistol that is different from all its competitors due to one thing: it has a tubular magazine.  If you don't know what a Tubular Magazine is, then come on down to my Guide to K'nex Guns.  (It's in Step Two, for those to lazy to dig through it.) 

To my knowledge, it's the most compact tubular magazine gun to date.  These are the instructions to build and fire it.

To entice you to build, Insight also:

Can hold up to five bullets at a time.

Gets about 25 feet; this is very good for a pistol of this size.

Uses a red rod sized firing pin.

Has a comfortable handle.

Requires no cut pieces. (Nor do any of my posted guns, come to think of it.)

Shoots green rods. (A downside for some, but a pro for others).

And... Yes, the gun has a theme song: Insight by Joy Division.

Step 1: Build All the Things

This is just a picture of all the different panels and doodads that are needed.  Just build all the panels and stuff that's shown, and the next steps will tell you how to piece it all together.

Also of importance, those bands do not have to be cut and tied together; it would actually be better if you left them intact; I just ran out of full looped bands, sadly.

Step 2: The Internals: Part One

Just follow the pictures.  

If you have any questions, please send me a comment explaining your troubles.  I'll be happy to help.

Step 3: The Internals: Part Two

Just keep on doing what the crazy pictures say.  They know what they're talking about.

Please leave a comment with your concerns if you need help.

Step 4: Encasing the Internals

Just follow the colorful pictures!

Step 5: Putting on the Bands

Keep in mind that none of these bands have to be cut and tied; actually, it's better if you don't.

Again, comment if you have a problem. I definitely won't will be happy to help.

Step 6: How to Load and Fire

This part tells you how to load and fire the gun.  It's pretty self-explanatory, I would think.

If you've come this far and have built this, I hope that you enjoy the gun!

(If it's not working, see the next step.)

Step 7: What to Do If It's Not Working

Picture of What to Do If It's Not Working

If your magazine is acting funny, the best thing to do is to get a rubber band and use it to pull the bottom rail upward.  If you go back through this instructable, the bottom rail will be labeled with a note and an explanation of what to do when the mag is not working. (What I've said here.)

If your trigger is not working you can do one of two things:

1. Put less rubber bands on the firing pin.
2. Get a hot glue gun and glue the one piece of the trigger together.  A note will be placed to show where you should glue if you want maximum power.

Nice gun :D

Knextremely stupid (author)2014-12-25

Yea i finally got it right then it bursts open into pieces

I'm sorry to hear that. I remember modifying this thing a lot so it wouldn't do just that. Maybe I just sort of rigged it? (Sorry about the four month later reply.)

Btw, I love the durability of the gun. That and the concept,but in the future it would greatly help to have a parts list and such. Until next time, Keep snapin' em

Dude keep up the amazing ideas!!!

megustatrains (author)2013-08-01

I will build this. rather better than most pistols on the site :D

Thanks! That means a lot! :D

You should tell me how it turns out, especially the mag, as I want to find ways to improve it. Honestly, I should have made it more evident in the description, but this is kind of the beta test to see how it works for people. The instructable will probably be edited once and if improvements are made. :3

Idk what i could do because i actually kind of suck at finding good solutions to a knex gun XD

Oh, so is it working or not? I am confuzzled. >:?

it didn't D: the internals seemed very tightly packed for me, so the kept on popping out constantly and pushing the outer shells open.

So the entire thing was splitting itself open? Did you put the little blue clip on the blue rod in the back? I put that there to fix that probably and it worked great for me.

k ill try that.

Did it work?

i actually have ben the builder's spas 12. it has most of my pieces so when i get bored of it ill remake this.

is the blue clip on the right side the 1 you meant?

oh lol i missed that XD

That is definitely your problem. Without that, it split apart for me, too. :3

Ok. :P

A very interesting gun you have here! I must add it to my list of guns to make after knex war 2013. (Yes, a list... it's getting to be a habit...)

JonnyBGood (author)JonnyBGood2013-08-07

Oh... and I voted for this awesome concept.

Thanks again. :P

Thanks! I would love to know how it turns out! :D

Not bad. =D

Thank you. :D

You are very much welcome. =D

:P I am indeed very welcomed.

Thanks again!

Nice build man

Thanks! :P

Cool! Finally a gun i can build without a black rod!!! YES!!!

Yep! The mag might take a little bit to get working, but it should work fine once you've got it set. I just wouldn't point it at the ground before firing if I were you; it might fall out.

Oh, and did you ever finish my DOT Pistol? I'm curious. :3

Oh yeah! I did! A long time ago... I took some pics though, and I will send them to you later today! I also made some additions:

-Front and rear Iron sights
-Ammo holders
-Shoots Oodammo
-Purple rod instead of hinge
-I made the trigger more secure

Overall it's a great pistol with great range! Definitely one of my favorites and the second K'nex gun from someone else I ever built!

Unfortunately I had to dismantle it, but like I said I took some pictures! I will definitely build it again-and also the pistol in this instructable!

And we still have to finish the Screamline... I probably won't get around to rebuilding it until sometime after August 12th... ;)

...But like I said I'll send you some pics later tonight! :)

Yeah, we do have to finish that screamline; didn't I send a picture of what I did so far? If so, maybe we could start from there. :3

Yeah, but i have a few more things to make first...!

Yeah, I know. I meant to say that when you get to that we can start from there. :P Did I sound a little too ambitious?

Not really. :/ :P

Oh, ok. :P

Oh, and do you have to cut that loop connector on the plunger? If so then one of you're pros is a LIE! ;3 jk :P

Sorry, I meant firing pin... Too much Nerf modding... :/

Here is/was my DOT pistol:

Pic 1: The finished pistol
Pic 2: It can shoot Oodammo!!! (Or anything else) -It can even shoot Nerf darts (in a special way)
Pic 3: My ammo holder attachment
Pic 4: Gun with all of my attachments (can you spot them all? The gun holds ten rounds total when loaded)
Pic 5: Additional ammo holders
Pic 6: Yet another... ammo holder

The only problems I had were
-I only have grey rods... No black or clear ones :(
-The instructions... Well... Umm... Yeah... :/ I think you need to add more for building the transfer... I couldn't figure out how you got the green rod inside for a LONG time... But I figured it out... Eventually...

Yeah, thanks! As for the transfer, I pretty much admitted that in the instructions. :3 I probably should go and fix that sometime. It's looking great, by the way. :D

What range did you get with it, exactly? >:?

I didn't shoot it oitside, but with its onherent power I would say its capapble of getting 20-30 feet woth one #64 band. I didn't put more bands on because it would have broken the grey rod I had to use for an FP. :/

Not bad! I'd say I got near double that with two. You should buy a black rod! :3

Yeah I might buy some from a friend... He has loads of K'nex that he doesn't use down in his basement... He's now a lego fan... >:(

Oh, wow...

Have you shown him what can be done with K'nex? He might appreciate it more then; maybe we wouldn't want that, though, because you kind of need that long black rod. :I

Thats exactly my question... It'd be cool to have one of my "in person" friends be a k'nexer, but I'd also like to buy his K'nex... :/ I dunno...

If I can get him interested in getting an Ibles account and becoming an Ibles K'nexer, maybe I won't buy them. We'll see...

Gah! The conflctions! :P

Wow... I must have been in a hurry when I typed this one...



Oops... Extra picture... :/ sorry...
