Introduction: 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.

Step 1: What You Need

Step 2: Make the Barrels

Step 3: Make the Trigger

Step 4: Connecting Trigger to Barrels

Make two of the first picture

Step 5: Making and Attaching the Handle

Step 6: Inserting the Ram and Adding Rubber Bands

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.

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!
