This was mostly constructed of spare parts left over from building my other two pneumatics. Its nothing amazing, but I like it nonetheless. Plenty of power, but this .5" barrel has to go. It has a 2" piston valve of the adjustable type that I was discussing yesterday in the pneumatic forum. The trigger is a homemade push button made from an elbow and the push button from a tire filler gun.

mmm.... piston valves. Love 'em
Only two suggestions: 1) shorten the pilot volume and 2) drop the DWV parts, like the tee and the female adapter. But for spare parts, nice

Very nice for spare parts. And yeah, try not to use the DWV.
Rmich, how can you tell if the female is DWV?

magic 
no, but you can tell by the shallow socket depth. I am talking about the female adapter connected to the DWV tee near the sprinkler valve, just in case you were wondering

| Yeah I thought you were talking about that one. And yeah, it does look shallow. I learned something new!

| Yeah I know the deal with drain waste and vent, but thats all that my Lowe's carries, and I never go above 50 psi anyway. I agree with you guys that pressure rated fittings are the way to go. You do know that some deep socket fittings are still DWV though right? I wouldn't trust that a deep socket means a pressure rated fitting. Thanks for the responses guys.

Just look for ASTM D2466 on the fittings, and then you'll be good.
"Home Improvement" centers usually only carry DWV, (in larger diameters anyway), because in construction, that's pretty much all plastic pipe is used for... draining into a septic tank and venting gas traps.
Plumbing stores or other hardware stores will sell plastic pipe fittings in the pressure rated/potable water variety. You may still have trouble finding large diameter fittings, though, because face it... Who needs a 4" water supply running to their horses?
EDIT: McMaster-Carr may be a good solution for you. As long as you buy a bunch of stuff together, (to avoid any high shipping costs and waste of time), they are pretty fair on their prices. Also, you usually get your order delivered to you next day or the one after that, (except over weekends).

Unless you want to obliterate your ammo (and your target,  ), it's optional to go above 50 PSI. 
I like it, and the DWV is fine as long as you keep the pressure low. I've taken my DWV to 100 PSI multiple times and never have had any problems with it (not smart, but shows it's not as weak as everyone thinks).
