Picture of Semi-auto K'NEX gun
dscn1772.jpg
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"

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

i only had small elastic bands so i put the elastic band through the hole of the yellow connector on the recoil thingy this works so well and it fires single shot

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...
not so cool3 years ago
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.

i have dual monitors a 23 inch and a 22 inch
if you load it and oull the recoil part instead of the trigger it works very well as a shot gun
zmxninja5 years ago
do you have to add the recoil rubber band
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.
i didnt have a big 1 so i just use 4 small ones
I built this gun last week. it works pretty well. on a completely unrelated topic, i found this site and it says if people click this link, i get money. click the link!!! you will obey the link!!! http://tinyurl.com/392aktn/index.php?id=1fb71d42ace7110f91561b4933da9c26
NO! (clicks link) OH MY GOD!!! XP (dies)
