1. Use a cpvc/pvc tee. It appears in the photo that you glued brass/copper RSCB assembly to an elbow. Using a tee will definitely help the seal and allow you to experiment with different barrel/chamber lengths.
2. shorten the stub between the elbow and the plunger tube. This reduces deadspace.
3. Seals on sledgefires tend to be pretty good stock. Did you remove the air restrictor?
4. Go to a hardware store with the stock spring and see if you can find something stronger that you can replace it with.

Currently I do not have access to expoxy, would hot glue work?You should be fine with the stock sledgefire spring as it is fairly heavy (10kg). Other then that, you should smother epoxy on all of the joints to get a really good seal.

How is the elbow attached to the barrel? Just glue? You really should have a T in there, it's just the best way. If you want to make a pump-action fit easily over 1/2" PVC, you can use a bunch of couplers or IIRC 3/4" 200 PSI PVC "thinwall".
If it were me, I'd test that the blaster can fire through an RSCB before messing with the pump action. It may not have the plunger volume required. Build one according to this guide, exchanging your barrel material for the sleeved CPVC used in the guide. Use Sch 40 or 200 PSI 1/2" PVC for the RSCB chamber, Sch 80 might be too tight for the darts to move the way they need to.

I've seen people fire demolisher missiles off sledge fires befor with almost no issues, this thing has enough power to use an rscb.

I got to thinking last night, instead of an rscb, how about an inline rscb?
Instead of using a pvc tee and elbow, why not slide the rscb in another piece of pvc?
Try it, let us know how it works. That sometimes fixes the issue of an RSCB working in a blaster.
It's *super easy* to drop an RSCB onto something if you've already got the parts. Check that your RSCB works with something it *should definitely work on* (BBBB, Titan, homemades, maybe a BBB if you do a short barrel), then try it on the blaster you want to test it on. If it doesn't work, the blaster may not have the power to make it work.
I'd test it for you but I don't have a sledgefire.

4: most of the springs at my local hardware stores are not that long or are only good for reverse plungered blasters. And also because the prime on this thing with the stock spring is extremely heavy.
ALSO, this blaster was bought from goodwill for $6
