Ah, there's the thing, in order to secure the copper, since it wouldn't stay put very well just being attached to the end of the plunger housing, I filled some excess space with glue.
What size cpvc would you recommend? What's the difference? I know that standard and schedule 40 pvc is plain white, or slightly off white.
Get 1/2 in. CPVC not Pvc. 1/2 in. Pvc's thickness is too big for a pistol, like the nightfinder. While your there pick up some cpvc couplers, and a hacksaw or pipe cutter.
