Here is a quick preview of my gun. The barrel is Bic pen tubes wrapped in a 1/4" of glued paper to make a paper barrel. It worked great and was looking great, but I was impatient and didn't let the glue fully dry before I started getting rough with it. It broke so I made a new barrel. I don't have pics of it, but it does not include paper. The Bic pen tubes work great for 6mm air-soft bbs.

The valve is a 1/4" QEV and the exhaust valve is a standard blowgun valve just cut down a bit to make room for a Bimba air chamber. Just because there is a chamber doesn't make it fully portable, I need to be hosed into a large air supply, whether it be CO2, air compressor or some other large bottle. I am however looking for ways to make it portable with the same setup (or very similar) as I have now, I you have ideas, let me know :)

The benefit of the QEV is having the ability to shoot semi auto. That being said, as of now it is muzzle loading, but I plan on installing a magazine of some type holding up to 20 shots

This is also a rifle, I rifled  the inside of the pen tubes with a small bent nail, for one length of pen tube there is two rotations and there are four pen tubes. From past experience using pen tubes as barrels, this barrel has been the best.

The stock so far is made of cardboard and will continue to surround the trigger assembly, this is mostly to give the barrel support and make the whole gun robust, however i want to be able to disassemble the gun without breaking anything and being able to do it quickly and easily.

Feel free to ask questions and give me our input on making it better, this is my first serious gun that I want to look good and work flawlessly sooo, any input helps. Hope you enjoy

The air chamber/action looks great but if you go to all the work of having such a nice action then why use pens as a barrel? Just go to the store and buy a piece of 6mm pipe to use as a barrel. Also cardboard+gun=bad.

I'll get around to buying a new barrel. I wanted to test the rifling technique on pen tubes first to see the performance. It works sooo much better than any metal smooth bore barrels I have, so I am in no rush to change it.

The cardboard is very strong with the layering techniques I am using. You would be surprised. Check these guys out if you don't believe me :P.

It doesn't hold any pressure, is easy to manipulate and change, and virtually free material. If my final stock works well, I might transfer the design to wood, but again I am in no rush
