Coupler your gun. Easiest thing ever. Just cut of the stock barrel at the beginning of the valve stem and glue on a coupler. In the picture you may be able to see the teflon tape I wrapped around the coupler before gluing it
I also wrapped some teflon tape under the o-ring because the o-ring on my blaster was horrid. There was a line going around the outside of the o-ring with little flakes of rubber hanging off, giving it a horrible seal. I should of put more on, because it isn't helping at all. I think I'll just take it to Ace and get a replacement. Incidentally, however, the teflon tape covers the OPRV venting holes on the sides in such a way that it squeaks when the gun is pumped fully. Which is awesome.
Now cut your shell like so.
Also cut a hole for the coupler.
Now begin assembling your RSCB with your street elbow. Make the part of the elbow that makes it a "street" elbow the part that will be inserted into the coupler.
Now start making some cuts on the shell. The first, deeper cut in the picture fits the end of the tee. The second fits the PVC holder section of the RSCB.
Here you can see how the tee fits into the first, deeper notch.
Now cut down the back part of the shell so the PVC holder section will fit. The best way to do it is go really slow, constantly test-fitting. Also make sure that you take equal amounts of material of of each half of the shell.
Now cut a holder section and glue it down. DO NOT GET ANY GLUE OR PUTTY ONTO THE TEE. I just used putty because I was low on super glue, and too lazy to deal with epoxy. I would recommend actually epoxying or super-gluing it down first before adding putty. Another thing: ONLY ADHERE THE PVC TO ONE SIDE OF THE SHELL. You're going to want to be able to open the blaster in case of a trigger break or something.
Onto the barrel. Funnel out the PETG on one end.
Do the same to one side of a PVC barrel sheath you should now make.
I did this to both pipes by twisting wire cutters like so. Apparently the corners are sharp enough to cut into it (and obviously it can bend the PETG).
Now wrap some e-tape around the PETG and goop it into the PVC. Make sire the funneled ends are as flush as possible with eachother. Now you can assemble you RSCB.
And the best part? You can still remove the RSCB by tugging on the elbow and tee.
