Thread the head of Drain Blast with 1/2" thread cutter. Screw on the Brass Hose Barb adapter. You might need to sand down the barb fitting part with fine sand paper (200 grit) to fit the Brass tube to the adapter.

Attach the hose clamp to one end of the brass tube, this is the end that goes into the chamber. Cut the 1/2" Snap clamp into the break action chamber for the nerf dart. Zip tie one end to the drain blaster. Zip tie the other end so the barrel would not fall out. Cut enought space on one side of snap clamp such as the brass barrel can be deattached from the barb adapter and rotate to accept nerf darts into the barrel. Cut some small notchs on the snap clamp so the zip ties would not slide once tie up.

Put on your safety glasses, load nerf dart into the barrel, give it a few pumps and blast it away. I 3D printered barrel front sight to make it look like a rifle. @40 PSI (more than 15 pumps) , it would shoot a full dart at 300 FPS, a half dart at 280 FPS. DO NOT AIM AT PEOPLE OR ANIMAL. Nerf would not sell anything this powerful for a reason.
