I can't seem to figure out how you are planning to make the gun work....


No thanks, i enjoy them all even though they are money pits. =p

As for how it will work. Usually the co2 travels two ways in a normal paintball gun. 90% goes through the front to propel the paintball and 10% shoots up the paintball feed ramp/tube to agitate the paint to drop and rechamber.

I cut the feed tube/ramp off and am in the processes of plugging it up completely so it can only go out the barrel. I plugged the barrel off already and only made enough room to put in that hose out the side. The hose will go back to the end of the blowgun. So the co2 will go straight from the bolt into the hose then through into the blowgun.

The biggest issue i will have is that i want to make it a bolt action with a magazine. I already have an idea planned but its getting the minor details figured out that tough.

finally got a day off, might tinker with this some. Not sure what to use to plug up the feed tube where the paintballs went in yet.

Kind of contemplating making the barrels changable so i can use it as a pellet gun too or fire real airsoft ammo. Something to toy around with in my head but it all kinda depends on if the bolt will recock on fire without a painball there but im guessing yes because of resistance from the small tube.

I still think it would be cool to use the blowgun darts in a magazine fed bolt action but that would most likely require me to buy another blowgun and chop it into increments long enough to hold one dart. Btw, blowgun spikes and broadheads look fun =]

Ran into some trouble, the line that goes from the c02 tank to the actual gun sprung a leak so i ordered a new "remote line" which is just a coiled hose with a quick disconnect coupler. I get it in the mail and find the part that goes into the gun is to large. Not sure how to go about making it work.

Heres a pic of the old and the new.

If the old one was one piece it would make things so much simpler but to make something like i have in the bottom left corner may be harder than it initially seems because the part that screws in the gun is one piece and the hose and brass fitting that jams up close to the bolt is another.

Well I'm slightly discouraged. I was just going to take the nipple off the new cord and tap (as in tap and die) the old free floating piece but the opening is to large. bleh....... any suggestions?

Not sure how much pressure that hose will be exposed to but if your trying to do what I think your trying to do...

I would get a 1/4" female hose barb and thread out the quick connect fitting out of the "New Remote" and thread it into the hose barb female end and then hose clamp the barb inside your new hose?

long overdue update

I got the issue where the Co2 tank goes into the paintball gun fixed. Just ordered direct replacements. It was more expensive but I didn't have to "jerry rig" anything. Now its on to blocking the paintball feed tube off then seeing how the tiny hose in the front will work. I think im going to have to upgrade it to be honest. Probably to copper and make the pipes diameter bigger than the hose was.
