Picture of Mini Knex Gun

This instructable is about my awesome mini knex gun. it was the first knex gun i've ever made but since i made it i have improved it a little. hope you enjoy it.

Step 1: What You Need

Picture of What You Need

You will need:
-3 orange connectors (mine are brown because i was out of orange)
-2 Y clips
-4 light gray double connectors in the shape of a triangle
-3 single gray connectors
-3 blue rods
-1 white rod
-little green pieces for ammo
-and as many elastics as you would like (i use 3)

Step 2: The Main Body and Trigger

Picture of The Main Body and Trigger

build what you see below. i know most people don't like block triggers but this guns' power and shot length makes up for the trigger. the first pic is just the first step then you add the blue rod you don't make 2 body's.

Step 3: Handle

build as you see below, just 2 different views. the black things on the brown connectors are the Y clips

Step 4: Ram Rod

It's awesome! What do you recommend for ammunition? I've been using smaller k'nex pieces, but I want to find the optimal projectile to fire.

Please don't post stuff like this. At least give it a true trigger and bullet lock. 

Fred da Bunny (author)Lowney2009-11-13

the bullet doesen't fall out, the gun is small and powerful for its size, and i like it so be quiet and don't look at it if you don't want to

Lowney (author)Fred da Bunny2009-11-14

I'm saying posting stuff like this is pointless. Surely anyone could've made it without the instructions. I heard you had a mag-fed pistol. Post that, it'll be much better and people won't see you as a n00b

Some people have no previous knowledge in knex, And would not be able to build it. What about them?

techdeck12 (author)2011-01-25

Fred da Bunny (author)KKcool2010-12-09

what other instructables do you have like simple guns

my bow is fairly simple and powerful

Why did you need to post this? anyone could make a gun almost exactly like this in about 10 seconds if they wanted to. are instructions really needed?

this one has a nice block trigger and, i can post whatever i want, if u dont like it dont look at it

You did not answer my question. I asked if instructions for this gun are really needed? we already have this gun which is more or less the same thing as the gun here. Then there's the fact that I am sure you are capable of building things way better then this. all this gun does is make you look like you don't want to try.

You can build and post anything you want, but just because you have that right does not mean you have to post each and every gun you make, no matter how bad. If you want anyone here to like you, you should try making better guns.

that gun is a lefty mines a righty. jk. ok ok ill post my pistol with a 10 shot mag then. it'll take awhile though

ravens claw (author)2009-09-06

your gun is awesome thanks

no problem

no problem, im glad you like it

Fred da Bunny (author)2009-09-04

i just removed my comment cuz it didn't fit there

Fred da Bunny (author)2009-09-04

I dare you two to make it, see how powerful it is, and how comfy the block trigger is, then tell me your results and rate it

agent harmsy (author)2009-09-03



well i like it alot and it's the perfect hidden weapon in a knex war because it so powerful for it's size

Please don't post these simple guns.
