Intro: Knex 8-shot Semi Automatic RBG (rubber Band Gun)

Step 8: It Should Look Like This

Step 9: How to Load and Fire

Put one rubber band on the tip of the barrel and stretch it back onto the white rod on the cogwheel the is straight up. the while holding the cogwheel release the handle part a bit forward and pull the cogwheel back until the next white rod touchs the handle bit and reapeat. To fire it, all you have to do is use the rods on the cogwheel at the bottom of the gun as triggers. Pull it back until it fires and the handle should stop it from firing the whole magazine. However if you put on about 6 or more rubber bands it can sometimes fire 2 or 3 rubber bands at a time. So put a little bit of pressure onto the handle when you fire.

    Agreed! I made one that's not Knex, but that's just for durability. I have nothing against Knex, I just don't like how easy it is to break the guns made with it. That said, I'd have to say that this one could be a little better. It's not bad, but not great, either.

    Hey Kickback, you should put my escapement trigger (click on my name, it's the only one there) on your gun and modify your sprocket with green rods, it will allow you to shoot one rubberband at a time plus it hardly ever missfires.
