you need:
10 in. of pvc
1/2 in. pvc connector
crayola marker
hot glue gun
duct tape
hack saw
You don't need to open the gun up to do this mod.(unless you want to take the scope off the small soldiers 500, you have to open it because its glued on one side)
Its very simple if your looking at the gun . Take the gun a cut the barrel right before the case. Cut a three inch piece of pvc. Wrap duct tape around it and glue it in the cut down original barrel. Get your crayola barrel and glue it in the pvc. Then shove your pvc connector over the pvc.Then cut a 6-8 inch pvc barrel. To plug the pump, pump once and when you pull the pump out give it a tug and after doing this a few times it will come out. Fill the air release valve with glue and super glue the cap back on. Now you just need to put a dart in, put the barrel on and pump 2 times. Do Not Pump More Than 2 Times or you will blow the tank. The gun should have amazing range and velocity now.
I did this mod a long time ago but one day I pumped it and the air came out the front of the valve and wouldn't hold pressure. But I heard about spraying WD40 on the valve and now it works again. The gun should be getting about 100 ft flat beacause it hits the wall harder than my AirTech2000. I don't have an exact range because its snowing outside right now. Enjoy your modified SM 500
