It's simple: Jux is built for compactness and power, and it handles both very well. It has a new sort of trigger, similar to a sear, but a bit different. It also has a new energy transfer, different from my DOT pistol and the NAR, which I can't show you, because it seems like K'nex innovation is down for good; my apologies. A video is above for your viewing pleasure, and instructions are here.

Confused about K'nex gun terminology? All that you're looking for is explained here.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Piece Count


White = 8

Yellow = 12

Orange = 6

Red = 8

Grey (2-prong) = 9

Grey (1-prong) = 10

Bright Orange (45 Degree Prong)

Tan (With Prong) = 12

Blue = 3

Green = 3


Yellow = 2

Blue = 2

White = 27

Green = 39

Red (Preferably the tan, tougher version shown on mine) = 1


Wheels = 2

Female Ball Socket = 1

Y-Rods = 3

Step 2: Trigger Area

This is the area where your firing pin is going to be blocked, making it very important to build correctly. There is no question: if you build this even the slightest bit different, there is almost a guarantee it will blow up. For your own sake, please don't build this wrong and then try and fire it.

Step 3: The Handle

This handle is extremely comfortable. Make sure to fill it with all of the internals!

Step 4: Handle and Trigger Area Connecting

In this step, you combine the comfy handle and the trigger area. You're on your way to being done; your gun is really starting to take shape now.

Step 5: The Barrel

The blue connector thing attached to the green rod placed inside the barrel is where the energy is transferred, so it would be worth your time to make sure those pieces are strong.

Step 6: Trigger Guard

To make sure no one kicks the gun right out of your hands, this should help. It will be secured later.

Step 7: Connecting the Barrel/Clamping It Together

Make sure to read the image note on the last picture, otherwise, your trigger will not work!

Step 8: Handle Coating

This is to make sure the handle is as comfortable as possible.

Step 9: Rubber Band Placement

The trigger works without rubber bands, but you still need to have rubber bands for the firing pin. Place them as show.

Step 10: How to Fire

Pull the firing pin back until it stays, push a bullet in until it can't be pushed back any farther, and pull the trigger. Oh, yeah, and it has sights too. You could use those to aim.

Thanks. If you have an afternoon to kill, go for it. It's pretty entertaining. Thanks for the vote. (I'll get back to you on that story; I'm out of state, so it's diffifcult to do anything at the moment. My apologies.)

Thanks! How's the video looking? I'm trying to assess my ability to use adobe software, and would love feedback.

The video was good, but I'd add a little commentary and explain the gun a little. Watching you fire the gun over and over got a little repetive and boring.

Are you going to make instructions? It would be awesome if you did!

Somebody got artsy with their main image and the color splash feature in photo-editing software. :) Color splash works well for KNEX.

This is very well-documented, and good luck in the competition.

Thank you. I had a ton of fun one afternoon going out to find places to take pictures with this thing. I didn't actually have to use photo editing software, though - it was just a filter on the camera itself. I'm glad you like my instructable regardless!
