Introduction: Three Barrelled Knex Gun

Picture of Three Barrelled Knex Gun

I was trying to come up with a mechanism with a firing pin and a true trigger. This gun is the result and although it isn't very powerful, i'm hoping someone will be able to improve on my design.

And you're done. Please feel free to ask questions and leave comments.

And remember that this is a prototype and does not work very well. so please, not too much critisism. Thankyou

Only thing better would be if it could shoot each barrel independantly. Would solve my problems in a battle of always running out of ammo when needed most.

how do you add true triggers to a gun? im still doing the snap triggers

i could tell you my system, but it's complicated and bulky. on the plus side, it's unjammable and has a 100% efficiency rate: you can pull it half way and it will fire!
