So, I made an RSCB out of 15mm PVC, because I couldn't find anything to make a basic one out of that had less dead space. I nested PETG in it for the barrel. Stoppped using it, because it was huge and chunky, misfired, double loaded. I generally just hated it. All the while, I was thinking, less dead space, less dead space.. Then, the other night, I looked at a piece of 16mm Conduit and ding!!
So, I give you all the prototype of my custom RSCB!
I simply designed and cut pieces to fit each other, then glued them together. I used hot glue and tape for support on this one, but once I've been to a certain shed and used the jig to get some perfect cuts, it'll be a lot smoother and will be glued together with three-day epoxy.
This particular RSCB is made specifically for my PAS and fits it perfectly. There is barely any dead space at all. I was thinking of possibly nesting 16mm Conduit to reduce dead space even more, but I feel it may reduce air flow at that point. This RSCB actually sits to the side of the little iron sight piece on the top of the blaster, as it sits snug to the round portion of the shell. It has a 180mm clip, 75mm barrel. I get no misfires with silicone tips with the reamed out 16mm Counduit barrel.
Anyone have suggestions on an end cap for it..? Lol.
Would be interested in selling these if anyone was interested, build custom for each blaster. Once I have a final, effective product, of coarse.
Update!

Few improvements. I did a few different barrel lengths to test, after I fixed up all the air leaks. This is a 9" barrel of 16mm Conduit. Reamed, as with any and all Conduit barrels of mine. The barrel seems to give quite good performance, although I haven't added a spring yet, so it's not getting as much power as it could.
The glue looks tacky, I know. This is the prototype, so it's made to perfect how it operates, not how it looks. I glued the joins, then glued the glue, then put a bit of glue around the joins of the glue, then glued some more of the glue. Then I smothered the shit out of it with, you guessed it, more glue! After going over it for all air leaks and gluing them up nicely.
The end cap is great, gets an excellent air tight seal, just pushes in, then you just pull the loop to get it out. It's made out of the tip of one of the megas that came with my Hand Cannon. I cut a small hole out, tied a bunch of knots in the loop so it would jam in one end of the little tube that goes through the mega tip, slipped it through, then glued up and around the knot. Then I simply wrapped electrical tape around the stem of the tip until it fit perfectly in the 20mm Conduit. Not too tight, not too loose. Although, if you have no darts in the RSCB, block the barrel with your hand and fire, the cap gets blown out, lol.
The RSCB is literally perfect for this blaster. There's so little dead space, it's excellent. The silicone tips work so well in it, except when I've made one with too much super glue, which creates a kind of lip or ridge around where the foam meets the tip. That causes a few problems. Otherwise, not a single misfire.
Thanks,
