Picture of Knex auto-loading marble gun
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)

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 very good entertainment if you go onto the roof and shoot at the ground near people! scares the crap out of them!
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
Please don't necro comments. It annoys everyone in the comment chain by sending email about something that they've left alone for a long time. There's also no reason to do so to say four words and a number.

has anyone got types to make it powerfuller
Bartboy (author)  coolcal6 years ago
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
