Open it up. remove the turret and the thin white piece that turns the turret.
Take out the Plunger and remove the white rubber seal piece.
epoxy putty on half a 15mm pvc coupler. Wrap Electrical tape around the stub to center the coupler.
To accomadate the coupler, cut the shell back where the yellow lines are.
Take out the plunger.
Wrap it in 3 turns of Electrical tape to help with the seal. Lubricate at will.
Add the spring from a longshot. It will slip right over the stock one.
To assist the catch, move the spring to this location.
The catch can be a real bastard sometimes. It retracts when the gun isn't primed. To fix that, remove this extension spring.
Then glue the catch down so it doesn't move.
Then put the badboy back together. Now here comes the cool bit. the inline clip
Cut 9 inches of Barrel material. I'm using Hep20. Your barrel material needs to have a tight fit on your darts. This is important for the function of this system. Wrap electrical tape around it where shown. It needs to be enough so it has an air tight seal on 15mm pvc
and of course, slip about 5cm of 15mm PVC over the top.
Have the PVC about 5mm above the barrel material. then sand the hell out of the insides so they form a sort of funnel.
Then apply hotglue between the barrel and the PVC to assist with the funneling.
Add more electrical tape to help hold the two together
Cut a piece of 15mm PVC to make the ammo clip. I'm using 25cm worth, which will hold 5 of my 5cm long darts. Join it to the barrel with a PVC coupler.
And we are complete!
Ranges. Don't know. but it can compete with my big blast.
