Introduction: Semi-auto K'NEX Gun

This gun is an 8 shot semi-auto rubber band gun with a twist, its made entirely from K'NEX!!! When you think about it its a very simple mechinism, i came across it while i was trying to slow down the fire rate of a fully auto gun (the fully auto gun was more like a shotgun becuase of the high fire rate and small magazine).

stuff you'll need:

1) alot of K'NEX
2) a computer (to view this page)
3) hands (to put it together)

Step 1: Make the Body of the Gun

Well pretty straight foward, assemble the pieces the way they are in the picture. This part holds the firing mechinism in place.

Step 2: Make the "Barrel"

make the pieces and put then together.

Step 3: Make the Firing Mechinism Parts

once again make what you see in the picture, these are the parts that make the gun fire.

Step 4: Stock (optional)

you dont need this piece but it makes it look cooler

Step 5: Other Parts

important piece that i can't think of a name for...

Step 6: Add Parts to the Body

your almost done!

Step 7: Add Parts to the Body (Part 2)

last step!

Step 8: FIRING Ang LOADING

streach each rubber band from the tip of the barrel to the white pin, only put one rubber band on each white pin. after loaded (doesn't have to be fully loaded, you dont have to put on all 8 rubber bands each time you fire) pull the trigger, theres 8 trigger so you have to move your finger up every shot

how to fire it

THIS IS MY FIRST INSTRUCTABLE, TELL ME WHAT YOU THINK OF IT

Hey. Great gun! This was the first gun I ever made. I generally have more fun with it by putting 2 bands in each white notch and then pulling back the recoil thingy to make it work like a rubberband shotgun. :) I also do this because it doesn't always fire correctly when using the trigger...

author
not so cool made it! (author)2011-10-14

hey i made one and it is really cool but when i put about 4 or 5 bands each white peace on and pull the trigger they all seem to fire. how can i stop this from happening.
thanks

No, I don't want dual monitors when one of them is a chunky old CRT (Even though I own one '-.-)

Lol, awesome gun! Scary lookin'. Somebody saw that sucker come out in a K'Nex war they'd forfeit right then and there.

if you load it and oull the recoil part instead of the trigger it works very well as a shot gun

author
zmxninja made it! (author)2010-06-25

do you have to add the recoil rubber band

author
dragonwriter7 made it! (author)dragonwriter72010-12-29

Absolutely. Without it, the recoil falls and the trigger wheel spins freely. In other words, it won't hold the ammunition, and it no longer works as a trigger.
