First here is what you will be making:
What you need:
1/2 inch pvc( Length depends on how many darts you want to be able to hold but about 8 inches is good for a lot of darts)
1/2 inch cpvc( For barrel)
1 1/2 inch pvc Tee
1 1/2 inch pvc elbow
1 1/2 inch conduit curving pipe( I think its 45 degree)
1 1/2 inch pvc endcap
Ok first you are going to want to get your parts obviously. Then you want to put the tee and elbow like so:
Just like an rscb.
Then add the curving pipe like so:
It might be upside-down, but im sure you can figure it out,
Then you need to make the barrel. I would follow Captainslugs guide to making hoppers, just use his method for the barrel.
Then assemble and your done.
This really surprised me when first used it, it fed just like a hopper. You may need to tip it down slightly every once in a while, but its not a big deal. The only downside i can think of with this is that It has a lot of deadspace like an rscb, but im sure with a good gun, everyone can get this to work. Also, you can tune this so the curving part is offset to the side so it doesn't impair aiming as much.
I sure hope this helps.
EDIT: After testing this design in a war (indoors) I found when I point this up it won't shoot. So It isn't as reliable as I thought. Although to fix that, you could get a check valve, and blow through the top if needed, but overall, this is just a prototype with a lot of work needed.
