Once again, not really anything original about the design as it is just basically a longer v4.1. Closed it is about 37" long and completely extended it is about 6' long. I have yet to verify this, but according to calculations it should make about 200 psi in the 5.75" long coaxial chamber. It shoots over 600 fps from its longest extention. (I think 625 was the highest I recorded)

The Tic Tacs make a cool whizzing sound at that speed. One was particularly cool when it ricocheted back at me from a tree about 50 feet away. It sounded like those cartoon bomb dropping sounds then bounced right by my chrony and whizzed by my ear.
Any ideas for a cool paintjob? For the extension part I want something to indicate how far it needs to be extended for certain velocities. 100, 200, 300, 400, 500 are pretty much what I plan on marking. As for the outside paintjob I was thinking some vertical pin stripes, but if anyone has some other ideas I am open for them.
