Nerf Double Rainbow Pistol

Since Thingiverse won't allow me to upload pictures, here's the Reddit thread: https://www.reddit.com/r/nerfhomemades/comments/kkpn0q/double_rainbow_shotgun_pistol/

This is a double 1" 200PSI PVC plunger tube, double barrel rainbow catch style pistol. There are two separate catches, one for each side; the trigger actuates both of them. If you have both sides cocked, you pull the trigger and it fires both. Currently working on two stage trigger designs. The barrels are interchangeable, with a bayonet-style lock. For a good air seal, the front end of each plunger tube has an o-ring, and a stub of 9/16 brass for the barrel to blaster connection. The barrels have a stub of 17/32 brass, which mates into the brass in the blaster for an air seal.

It makes more sense when you're actually building it.

For the blaster: you need doublerainbowbackend, doublerainbowbackendcover2, doublerainbowfrontend2, 2x doublerainbowchassisrail, doublerainbowbottomrail, doublerainbowtoprail, doublerainb
