I built this and it is actually my second pneumatic (my other is a little over under ball valve one) just a ball valve, 1.5'' barrel, 2'' chamber, really fun to shoot through magazines and other household items. Also fires a AA battery very far and gives a good kick id say a marble goes 125 yards and a battery about the same.

And if you want to get a sprinkler valve w/o Ebay, The Home Depot is a good place to start. I got a jar top valve there last year. Although, they may not be in season.

Nice gun. I would wouldnt bother putting a sprinkler on it though, save it for your next big gun and make something super powerful.

Hey pyromaniac, about your sig...
I didnt write that did I? I though it was joanna or someone.

PVC cleaner rocks my socks! It can be used as a primer, but I'd recommend primer also. I'd also recommend not taking it over 80 psi.

you can find them but they are difficult to find. i remember seeing one while back on the threads somewhere.
