yes it would be semi auto. all you need is a co2 regulator, how may time do i have to tell you? when the chamber is empty, you open the valve on the rgulator and fill the chamber. its not compecated, it like putting gas in your car, then its empty you put more in. the co2 will be mounted on the gun.

sorry, but I really wanna get this right.

ok, I understand most of it, there will be an extra tank on the gun, one with the chamber, another with a co2 tank, the tank will be linked to the chamber with a regulator, once the chamber is full I can just shoot.

can the chamber get more than one shot out already? or does it have to be filled, then shot, then filled, then shot?

and I googled co2 regulator and got a bunch of different stuff, could I get a link to one where I can buy it?

i told you... ebay. or you local paintball shop would probly have one.

you have the tank part correct. as to how many shots, on a practical sized tank, maybe 3 shots if you have alot of practice.

i gave you a link to look at.

ok, so 3 shots out of the chamber when it's filled.

Is there any way I could make it to where the sprinkler valve is directly connected to the regulator and it takes out so much every shot? that way I don't have to refill the chamber, the co2 tank is the chamber? So that it acts like this:? http://www.tshirtgun.com/bleacherreacherpro.htm

no, because it would have no room to pressuriz. you need a chamber. (take note of the .) if you want three shots you need a chamber like the one in the picture, but slightly bigger, maybe 1/3 bigger. that gun has a chamber, you just cant see it, its in behind the barrel.

How long does it take to fill the chamber? and why does it only hold so little? is there any way to make it hold more psi? a steel chamber or something of the sort?

http://www.spudfiles.com/forums/viewtopic.php?t=174& why dont you just make one of these. ( no, im not serious)

it would take, ohh, i dont know, maybe a second to fill. its really not a big deal since the co2 is already on the gun.

A SCH160 steel chamber would hold alot, but the valve would blow up, so no, you cant. i mean you can have a steel chamber, but it wont do anything.

your launcher will be maxed out at about 130 psi, after that you might be taking a unplaned trip to the hospital.

ok ok ok. I think I finally got it all figured out.


a co2 tank ran into a regulator, the regulator is ran into a schrader valve on a chamber I have made, the chamber is then ran to a modified sprinkler system, then the sprinkler system to the barrel.

The chamber would have a chamber will have a gauge on it, and I can just play around with the regulator and PSI pressure till I get it to as much or as little power as I want? But the regulator, I will just flip the lever and I don't have to watch the gauge go up and then quickly close the lever, the regulator will prevent it from letting out more than so much PSI correct?

All I need is for you to write out a parts list, but categorize the list please, like

Chamber:
4" Sch 40 pvc 3' long
4" End Cap

and so forth, it's easier for me to know how to put it together than.

THANK YOU SO MUCH!

sorta... do you want a paintball tank or a 12 gram co2tank. (if you only want 5-10 shots i recomend 12g tanks, they are 25 cents each and are disposable)

I have a 12 oz tank, and we'll be buying 2 more. How much would a 12 oz get?

you need...

1. 2 or 3 feet of sch40 2'' pvc (for chamber)

2. 2'' end cap

3. 2'' to 1'' bushing

4. 2'' coupler

5. about 6 inches of 1''pvc for connecting bushings to barrel/chamber.

6. 1'' threaded/NPT adaptor (2x)

7. sprinkler valve

8. blowgun (not nessisary if you by one that is already modded, like from bcarms or something)

9. 1/4 brass NTP nipple (againt, if you buy the modded sprinkler valve you dont need it)

10. 1'' nipple (2x)

11. 3'' coupler

12. about 2 feet of 3'' pipe for barrel

13. pressure guage

14. pvc glue and primer.

15. schrader valve (for compressed air only, if co2 you dont need it)

15. 3'' to 1.5'' bushing

16. 1.5'' to 1'' bushing

17. co2 and co2 regulator.

if i forgot anything you will quickly figure it out, but i think i got it all

edit- you will have to ask someone else on the co2, i really dont know because i have never used it on a launcher i made, only i bb guns.

thats for the co2, its the lever that you refered to, but no, you dont need it, but probably smart to have. it goes on the regulator.
