If you had a scrollsaw you could have used that, but, it came out well in the end. Also, where is polycarb found, cus I have looked everywhere and asked everyone, and I still can't find it. Also I can't find a 1/2 inch wye. I probably will just order it when I get the money necessary for buying them.
You can get polycarb off of Mcmaster. You can also make a wye using a PVC Tee and a 90 degree elbow.
X2 Hopper HPA blaster. Super soaker Shot Blast shell. I cut open the water reservoir and made screw ports. The inside is a 1st gen big blast with my X2 hopper system. The blaster is single fire and you switch between barrels with the polycab slide. This allows you to still be able to fire while reloading one hopper.
