I found some money a few weeks ago. So, I went Home Depot and bought an 8 Feet Long 1/2" CPVC Tube, A Bag of 10 1/2" CPVC Tees, 1 1/2" CPVC End cap, and some E-Tape. I have successfully singled a Longshot. The only problem is the air seal. There is a huge leak where the Tee and the replaced CPVC where the dart originally would go. I don't know what that's called.
