Introduction: K'nex Rapid Fire Slide Gun

Picture of K'nex Rapid Fire Slide Gun
While experimenting with different ideas for a new gun, I stumbled up the "K'nex Rapid fire Slide Gun". I was searching for a fun way to fire a gun, but still have alot of power. And what better idea, then to have it fire with the touch of a hands. Not everyone have those RARE Cyberk'nex motors that Perfect Duck, and some others have, so this build requires no motors, and no hard to get part. The gun can be easily modified to look as cool as you want. Also, it offers 16 barrels on the one I made, but you can easily make it as long as u want, maybe even up to 100! The possibilities are endless... Special thanks to sharpshot99 for the inspiring barrel design. I hope you enjoy the gun. :) I know I did.

Here is the first version I made of the K'nex Rapid Fire Slide Gun.

Here is version II, which features the same barrels, except this time, 20, and extra supports for vertical standing. As I said earlier, there are endless modifying possibilies.

Step 1: Parts Listing

Picture of Parts Listing

All 8 Two Barrel Pieces require the parts shown below. As for the base, it requires, 64 purple connectors, 16 dark purple connectors, 48 dark blue rods, 28 white rods, 6 yellow rods, and 16 green rods.

Step 2: The Barrels

Here are some images of the barrel design. They look very close to the design by sharpshot99. I thought that these would be pretty self explanetory. Make 8 of these. Good Luck!

Step 3: The Base

Picture of The Base

The base is the main component in this build that keeps the "K'nex Rapid Fire Sliding Gun" stable. These images are pretty self explanatory, and dont need much explaining. Feel free to modify it however you want. It can be changed to whatever you feel in a snap!

Step 4: Connecting the Two Main Parts.

Here are some more pictures showing exactly what the gun will look like once put together. The notes will explain certain parts.

Step 5: Ready, Fire!

Picture of Ready, Fire!

This is the easiest part of all! The firing mechanism is very easy.

Step 1- pull the firing pin back
Step 2-push the yellow rod in front of the firing pin as shown in picture.
Step 3-Insert blue,white, or green rod into the barrel.
Wave hand along line of yellow rods to fire them.

I chose to use my hand instead of something else, that way you can adjust the speed to however you like. And it makes it alot of fun.

OK, I found this site yesterday, found these guns, and now suddenly want to buy some knex . . . anyway, I have an idea for a mod. you take that first 16-barrel starter gun, and put it on a slider powered by a rubber band so that it moves over a pin to push all of the triggers, then you mount that on a VERY sturdy gun handle and have a trigger make the whole thing move and shoot them all. just an idea if anyone wants to try.

people have done that, they just wrapped it around a drum and made that spin, and you have a gattling gun, here is a link to one of my favorites.

I will do it, but that trigger will need to be VERY sturdy, as you said

Bartboy (author)Bartboy2008-06-13

sont work very well :(

person buy some knex and show us it sounds amazing.

That does sound like a good idea. Go for it.

Bartboy (author)bobbyk8812008-06-13

It is a UK measurement for liquid, "give me a pint of beer"

Joanassie (author)Bartboy2008-07-09

bobbyk881 (author)bighead54542008-12-23

Darth Trainman (author)bobbyk8812007-04-23

Oompa-Loompa (author)bobbyk8812008-07-30

Make it shoot at a controlled rate and it would be really cool

zap89 (author)bobbyk8812008-03-01

Metal4God (author)bobbyk8812007-08-13

ak 7 40???????????

Mad Cat (author)bobbyk8812007-04-23

This looks a bit like that idea I mentioned to oodalumps (see his Orangeboard). The sliding thingy would be horisontal instead and a rubber band would push it to the right. A pump action would pull back each firing pin and there would be a magazine to the left which loads each barrel. The trigger would push the slide the other way and the gun would fire. A challenge for someone to try:)

BLACKROD (author)bobbyk8812007-04-16

Yeah I've seen that before on Youtube, butI really wanted something different, I mean when those are hit, they all are firing in a downward motion, causing them to instantly hit the ground.

BLACKROD (author)BLACKROD2007-04-16

And By the way, I'm working on a dual chain right now. I cant wait to finish it. It's still beign folled with.

bobbyk881 (author)BLACKROD2007-04-16

can you post picks

bobbyk881 (author)bobbyk8812007-04-16


bobbyk881 (author)BLACKROD2007-04-16


Big Bubba (author)oodalumps2008-03-16

yeah! You could make gun that this fits in, and you slide it in a hole like a magazine, and as your sliding it, it has something that pushes those rods down and fires it!

Whaleman (author)oodalumps2007-04-13

i sortof did that, i put it on a chain, but i could only make five of them

bludfart (author)2008-06-19

um i have a problem theorange thingy makes it not fire

DrWeird117 (author)bludfart2008-12-06

You slide your hand across the top and hit the yellow rods.

newmariostar (author)2008-05-14

are those orange conectors floating?
