K'nex Double Barrelled Hand Gun

this is a handgun that I made to go with my K'nex Shooting Range. It has two triggers(one for each barrel) and shoots blue rods.

You will have a working gun after this step but if you want it to have two barrels keep going.

This is just the second barrel which is the same as the last step.

You will need five rubber bands two for each firing pin and one for the trigger. the trigger rubber band goes through the hole in the middle of the blue and black hinge.
