ok, shooting full 12g CO2s is obviously possible, but i dont know if i would try it. if u hit something hard and the CO2 break u are going to have metal shard flying everywhere at deadly speeds. just my 2 cents towards the question.

joemama I didn't say nobody liked you I said that not many people don't like bragers and a 758 fps semi is a amazing gun. I can't make a gun like that because of low funds.
"o yea well my paint ball gun shoot at 758FPS" is kinda cocky.
(sorry for the late post my dog chewed up the mouse cord :x and sorry if I was sounding like @$$)

Don't you realize that co2 is pressurized to like 900 psi?!?!?!?!?!? Imagine metal shards flying near the speed of sound!

okay well, this is my first time on this site in several months. Im glad you guys like it. And I think it is FAN-TASTIC that "joemama's" gun shoot at 758, but that is hardly faster that 400mph anyway. Look at the how-to's on this site in order to mod your own sprinkler valve.

Sorry, this may be a dumb question. But when you mod the sprinkler valve, I don't quite understand why the hose comes out of it. How is it used then? Ok, so you have inlet hole and outlet. Whats the one in the middle with the like air fill thing. The only guess I could think of would be that when you press the air fill thing, it changes pressure inside the sprinkler valve and activates it. Is that right? Anyways, could you give me just like a 10 sec. explaination on how its activated and how you threaded PVC into the sprinler valve. Sorry for the questions that may be stupid to you guys.

Thanks for you help, DNick454

Your right from what I read off your post... I was trying to get this done quick...

This is from Joels web page
Here's the source of these: http://www.spudtech.com/content.asp?id=21

See 2nd picture... the hose going to the blowgun replaces the hole where the solenoid is (the black motor type thing) and they make a bigger hole for the air on top of the diapragm to escape, making the valve open much faster...
