A lever action homemade would be very badass, but also very hard to pull off. Not only do you have either a tube or box magzine to deal with, you have a complex array of links and sliding components that make up the action. I`m not saying it is impossible but it will be very hard to pull off in PVC and other homemade materials.

This design has definitely not been perfected, and is a work in progress.
It utilizes a FAR-like pressure chamber setup, as well as a GNS/SCAR inspired fire control system.
The cocking action is acheived by a lever with a second, sliding fulcrum attatched to the pressure chamber. This lever is vaguely "Y" shaped, with the two arms of the "Y" on each side of the PC.
A second, but more expensive/fiddly option would be to use a rack+pinion system to achieve the cocking action.
The best part of the Lever Action is it allows the user to "spin-cock" the gun one handed. This in itself is radical, but it brings with it the possibilty of -dare I say it- effective dual wielding
Please post your comments/ideas.

Wouldn't your magazine need to be farther forward?
The pivot point is going to have a huge amount of stress placed on it. I also wonder about having enough mechanical advantage to compress a suitably strong spring with that lever arrangement. Which means nothing, it was just my initial thought looking at it.
Looking forward to seeing it evolve.

First, thankyou for the feedback. It is encouraging.Wouldn't your magazine need to be farther forward?

-The magazine's placement is questionable, I agree. I originally had a vertical one on the design, for simplicitys sake, but angled it in an attempt to give the lever enough room to complete its swing. If it is not possible to squeeze it in, it may need to be mounted sideways.
-The lever is the main reason why this project's viability is suspect. Although I think it would be possible to mount it with enough strength, the mechanical advantage is low. Perhaps adding a spring that assists the PC/lever on its way towards the butt would decrease the amount of force needed to cock it. Of course, then more force would be needed to bring the lever back.

As long as your gun has enough mass to carry enough energy into the spring to cock it and still make it all the way around.
That would be very badass if it worked.
Your design looks pretty good. Very simple. You will definitely have to make the lever our of something substantial. Like aluminum or steel.
Are you planning on shells or no?

Thanks for the comments.Are you planning on shells or no?
I need to get to Home Depot and get more PVC, and get started on this for real.
I was hoping that I would not need to use shells, however, my early breech designs have not been successful in maintaining a good seal, so I may need to.
I am somewhat anxious about using shells due to the whole extractor/ejector component though. To tell the truth, I don't even fully understand how it works on the SCAR.

As far as "evolution" of the plan is concerned, I have realized that to make the lever (pictured in the previously posted plans) work, I would need to give the track that the PC pin slides in a curve backwards. This way, the angle between the PC and the lever will not decrease too much/at all.

If you use a brass barrel and breech system it will be much easier to make sure that only one dart gets advanced in each cycle. And you could make the magazine at that angle shown in the image provided it's loaded with darts at an angle that is parallel to the barre. That would make the mechanism easier to design.
I had never thought about lever action previously because it usually doesn't offer the right amount of travel for priming a spring that I would prefer.
