guys, if you look at the first picture, he has a 12g co2 adapter running stright to the sprinkler valve. NOT A GOOD IDEA. 800 psi of unreg. co2 into something that holds about 150= disaster/explosion/death. Just use a regular chamber instead.

And how much will each shot cost then? Better to use one of the tire inflators that lets you release C02 in controlled fashion and get a couple of shots.

It could be a semi-auto if he decides to create an airsoft gun-Blowgun-

Otherwise, he would have to wait for equilibrium-Sprinkler Valve.

my dessign has changed frome what i first thought it would be,i just got a co2 regulator and ill now run it off of a big co2 bottel.ill make a chamber out of some sorta steel pipe to go inside the stock of the gun[so i dont end up exploding with little white pices of plastic flying at me].;]
