It is pretty straight forward. I super glued the Shotblast (SB) tank to the RSCB. Im using a thickwall PETG 5/8 fpr the rear clip and 9/16 for the barrel. The 5/8 PETG is the same OD as 1/2" CPVC.
The clip end cap is inside the nerf stock. So you just pull off the stock to reload the RSCB clip.

I used a LSFG trigger and ziptied it to the release pin of the SB tank. It is not in this picture but I added a third ziptie to the front of the trigger so it stays inline with the release pin.

The SB tank is a little offset which helps save space when putting it into a shell.

I reused the SS clip to hold the pump tube in place. None of the internals are glued or set in place. The shell just snaps around it and hold everything in place. So repairing anything is easy or I could switch shells if I made a shell to take these internals. The nerf SS sight is just for cosmetics.

About 5-6 pumps fills the tank I havent range tested it yet. But it shoots across my 40 foot apt and hits the wall with energy left so I estimate about 60 feet flat with CS darts. Im sure weighted stefans will improve range.
