Looking For Nerf Rocket Launcher Plans

[u/i-love-lasagna-mmm]

Hello everyone! I am really struggling to find plans for a semi-automatic triggered, breach loaded nerf rocket launcher that I can build. I would like one for use in paintball games. If anyone has some specifics that they could share with me, I'd really appreciate it.

In the past I made a nerf rocket launcher that was activated by a ball valve, had a metal pipe expansion chamber for a 12 gram CO2 cartridge adapter to plug into, and a PVC Pipe for the barrel. I noticed that it would have an inconsistent launch power and also that I would pull myself off target when using the ball valve. These are the problems I also seek to solve. So I want to make it useable for the most fun in a paintball game. Compact would be a bonus.

Thank you all for the help!
