Introduction: K'nex Machine Pistol: Refuge + Instructions

Picture of K'nex Machine Pistol: Refuge + Instructions

Nothing says tactical like my new machine pistol. With a high contrast front sight ideal for low light conditions, a large caliber internal magazine, and comfy grip, this is a K'nex gun that is a whole lot of fun.

The weapon is capable of launching yellow rods over fifty feet with two bands out of a magazine that is slyly concealed in the front barrel area.

Since I wanted the gun to have a machine pistol look, I gave it a faux small caliber extended magazine. The use of only one cut rod means that you can build it and not have to take half a dozen rods to the hacksaw. To make it still more builder friendly, I am including a part list, so you can be sure you have all the required rubber bands and K'nex parts.

Refuge could be one of the most modular K'nex gun I have ever build, with the ability to change calibers without changing the looks, low profile tactical rails on the upper barrel and receiver for scope mounting, and a rail under the barrel for a bi-pod or fore-grip. You can even modify the faux barrel to shoot blue clips. The back of the gun is set up to easily accommodate a stock, and the barrel is simple to extend, if you want to.

This gun is also my second entry to the K'nex Contest, and it would mean a lot to me to give me a vote. :)

Some credit goes to Instructables Member Lucas_The_Boss for the idea of the concealed magazine.


Looks great.

Shoots 50 feet.

Very reliable.

Good comfort.

Nice sights.

Concealed yellow rod magazine.


Does not need a lot of pieces.


One cut rod.

No removable magazine.

So... lets get to the part list shall we?

Step 1: Part List.

Here is the list of all the parts you need. If you want information on if a part is needed or can be substituted, just ask. :)

Green rods: 102

White rods: 55

Blue rods: 2

Yellow rods: 4

Black rod: 1

Yellow connectors: 44

White connectors: 20

Green connectors: 7

Red connectors: 14

Grey connectors: 4

Orange connectors: 20

Y connectors: 7 (If you don't have many of these, you just need the one in the internal magazine and the two in the handle.)

Grey clips: 11

Tan clips: 3

Blue clip: 1

Ball socket halves: 2 (Both of these may be substituted with orange connectors.)

Silver spacers: 3

Blue spacers: 10

#64 rubber bands: 3

#32 rubber bands: 8

Cut white rod: 1

Step 2: Internals and Faux Magazine.

This step should be fairly easy. Just follow the pictures. The pictures might be a little grainy, but I did the best I could considering I only have a cell phone for picture taking. Put the internals to the side when you are finished and go on to the next step.

Step 3: Handle.

In this step you will build the handle. Very simple. :)

Step 4: Putting the Parts Togeather.

Just like the title says.

Step 5: Pin and Use.

Here you will build the pin and learn how to use your new gun.

To shoot, put four yellow rods in the internal magazine. Add the magazine pusher and band as show. Pull the pin back, and pull the trigger.

Have fun! :)


The Crystal Railgun made it! (author)2017-03-06

Great and great-looking machine pistol! Can I use it as my secondary gun in my K'nex vs Nerf battle? It'll go on Youtube... please :)

The Crystal Railgun (author)2017-02-23

How does the mag on this gun work? This secret magazine is a little *too* secret... :P

It's right in front of the fake magazine. If you look under the "pin and use" step 5, you can see how the magazine is loaded.

OK, thanks! It's reassuring to see you active again.

The Knex Inventor made it! (author)2016-06-04

Great gun! This is the first one of your guns that I have ever made.

Kona-chan (author)2015-08-08

would you mind if I used the mech out of this gun? 'u'

CorgiCritter (author)Kona-chan2015-08-08

Sure! Use whatever you want.

knexcreator141 made it! (author)2015-05-25

I'm thinking of making one of these later when I have the time which one would you say was better?

I prefer Wrecktangle. One guy had trigger problems, though. It always worked for me.

On the shotgun does the ram rod go through the orange connectors? what's your next build going to be?


It's a AR style gun with a 17 round yellow rod magazine. It shoots about 50 feet, but is pretty reliable.

How does the magazine work?

Its just a normal magazine. It works like on Refuge, but it is not concealed and it works better.

sounds cool. You got any pictures .


It looks really nice. The magazine looks like a barrel 50 cal kind of magazine:)

Yeah, the magazine is too large for the rest of the body, but when I used a blue rod magazine, it kept jamming.

The magazine looks fine l. It looks like one of those underwater rifles off call of duty.

It's actually a real gun, not just from COD.

knexcreator141 made it! (author)2015-05-25

added Reds breach loading and foregrip and added my own stock the performance is great now.
And I like how you made the pistol grip it's very comfy. good job man :)

Looks great! Red's foregrip is really nice, isn't it?

Thanks! I'll have another gun posted in the next few days, so keep your eyes open.

Cheers and what have you got planned?

I built this gun great design eccept the loading part with mine the rubber and is either to loose or to tight so the bullet doesn't come out

CorgiCritter (author)mt412015-04-27

Huh, ok. Are you using the same rubber bands as I did? Make sure there is enough power on the pin, to overcome the friction of the other bullets in the magazine. You just need enough pressure on the magazine pusher to load a bullet when the pin is pulled back, so you might try a looser band on the magazine pusher.

If you have the time, I would love a "I Made it!" comment with a picture or two. :)

sandroknexmaster (author)2015-04-26

Looks good!

Thank you!

Lucas The Boss (author)2015-04-26

Oops forgot to
Comment, anyway the gun looks great! Is the mag a fake mag to hold yellow rods in a concealed mag? You gave me credit for the internal mag, I never told you about it....

Hmmm I think you blue mullet and myomy have something in common lol lets see if you can guess.

Thanks, you never told me about it, but I saw it on your R700 instructable.

And yes, I can guess.

Oh I forgot that I put a internal mag on my 700, lol I don't even know my own guns.

And no, this is the first account I have had on this site.

I know I just wanted to give you a hard time since every thinks your DarkOwl :D

Ok. That's good. :)

Kona-chan (author)2015-04-23

Looks a bit like thr Tec-9

CorgiCritter (author)Kona-chan2015-04-23

It does, but with a longer barrel and different trigger guard.

sonic broom (author)2015-04-20

Looking good now I have one more thing I want to build after the contest! got any ideas for a new gun i should make?

CorgiCritter (author)sonic broom2015-04-20

Thanks! And I really don't know. Do what you want, just make sure it works well. :)

sonic broom (author)CorgiCritter2015-04-20

I kind of want to make a pistol with metallic KNEX. Did you ever ask Zak for ZLG pictures?

CorgiCritter (author)sonic broom2015-04-20

Ok. I have not asked Zak. Someone was gonna do a mock up of the internals, but he never did.

sonic broom (author)CorgiCritter2015-04-21

They have some of KI saved on internet archive but there are no pictures so maybe you could get some ZLG info from there.

CorgiCritter (author)sonic broom2015-04-21

I don't need info, I need pictures! I don't care that much about the ZLG at the moment though.

I am working on a slingshot now. It is one of those ratchet guns, so range is only a 70 feet with oodammo, but boy, it can slice though cardboard with ease. :)

sonic broom (author)CorgiCritter2015-04-21

Yeah I know it sucks! that there are no pictures but maybe i will get some of the files from KI some time. The sling shot sounds cool. Have you built the SRv2? it is one of the best sling shots out there right? But it uses so many parts! You should make a good slide action pistol there aren't really any good ones and most of them need those silly rubber bands to hold the slide on.

CorgiCritter (author)sonic broom2015-04-21

Yeah, I have built the Srv1 and I modified it to a V2. It is OK, I guess. Mine never shot over 165 feet angled though. It did have a shorter barrel and my fin ammo skills were bad. If you have pieces, and time to spare, it would be a fun build.

Slide action? Maybe, I am not very good at pistols, except the the over sized ones. If I build a slider, I want it to be a removable magazine rifle with a slide.

After the slingshot I might try a looks gun, probably using a COD AW gun for reference. And no, I do not play call of duty, there are just some cool looking guns, like this.

sonic broom (author)CorgiCritter2015-04-21

That does look like a cool gun! do you believe what KK says about the SRv1 getting 500 hundred feet?

CorgiCritter (author)sonic broom2015-04-21

The v1 is only supposed to shoot 300, according to KK. The V2 is supposed to get 500. To get that range, you need KK's awesome fin ammo building skills, and surgical tubing.

I wounder who those guys in the vid were?

sonic broom (author)CorgiCritter2015-04-21

I think that was KK and some other guy.
