This is a auto-loading gun that is very simple.
It dose not use a trigger but you pull the pin back and let go to fire.

Step 1: Barrel

Build this (I couldn't find my whites so I used 3 yellows instead of whites)

Step 2: Auto Loader

build this. This is a bit tricky
Then put a white rod so that figure 5 is symmetrical.

Step 3: What You Have.

Build the firing pin. you should have these parts.

Step 4: The Gun

put the clip on like this

Step 5: The End

Put the elastic on like this

To shoot put marbles in the top like this then pull pin back.
Anyone interested in my trigger mod?
i put the clip back farther and it shoots 3x farther
Cool! I think marble guns are good because they hurt, but they won't cut you.
I reccomend wooden marbles.Thx!
really? i use marbles made out of cast gunpowder. probably shouldn't fire those things at humans, but they make <em>very</em> good entertainment if you go onto the roof and shoot at the ground near people! scares the crap out of them!<br/>
You have lost Karma. >: (
so? I already have most of the forces of the universe against me, why stop at only most? the worst that could happen is that i get spontaneously vaporized in the most painful way possible. what's to worry about?
Uh, Fallout 3 joke.
I Love fall out 3

The force of friction against you? wow? including gravity? How do you shpoot people with that than?
i saw people playing with a fireball type thing. it is a firework that flies around erratically in the air. it went into someones mouth.

I will make a very good marble gun with true trigger. Will post pictures soon.
Any recent comments?
has anyone got types to make it powerfuller
well, my modded one has a block trigger, so you can just add more elastics, but othe than that... oh, and marbles are more close range, cause this has bad range, but it hurts a lot more than a normal gun of equal size
don't shoot your eye out kid!!! lol
it won't shoot an eye OUT, but it could hurt LOL
