Your hopefully talking HPA ? ... and not Co2

Going remote bottle attached to gun has MANY options !!One only need look at a comprehensive paintball site such as: www.mcarterbrown.comIn recent years ( past 10 or so ) HPA has replaced Co2 for the most part.*Pending to what degree your willing to modify gun is your only stumbling point IMO.Even in PB guns we had small pocket PB pistols running on 12 gram Co2 cartridges that many guns converted to carry a small bottle under the grip. There is a dummy 12 gram that has a 1/8 NPT fitting in it's side allowing a flex hose connection to bottle. ( Down side is the SIDE of guns air tube alongside where 12 gram sits had to have a hole in placed threw it for the hose. )Other mods could be tapping the same 1/8 NPT into the side of an existing valve body and again like a PBG remote the HPA source.** Or you just foster fitting your fill port and connect up a QD fitting to tank/regulator.Honestly in the world of CUSTOM your limited only by your imagination or abilities.
You don't state what kind of gun you are thinking of converting to HPA so it's pretty tough to comment.... There are safety issues to be addressed.... With the proper precautions, and providing you protect the gun with a 1.8K burst disc to limit the pressure in the event of a regulator failure to 1800 psi.... you can mod both the 22XX/Disco series and the QB7X guns to HPA use.... I've done the shimming on Ninja regulators (only) and can help with that information.... Let us know what you're thinking of modding....Bob
You will need to locate the valve properly in the tube and seal it to the tube for a start.... assuming you are planning on pressurizing the tube.... A Disco valve will work great, get the screws with it, drill the tube accurately so that all three screws take equal load, and you have that part looked after.... You can use a QB79 tank block on the front end to mount the tank, but it is a really good idea to install extra screws for safety.... JDS Airman sells modified blocks that mount with 4 screws for this purpose.... You can then just thread a Ninja tank right into the block, and you are most of the way there.... It is really important to protect the gun from excessive pressure with a 1.8K burst disc.... That limits your regulator output to 1500-1600 psi, and the closer you push it the more chance of blowing a burst disc.... If this is your first attempt at HPA, I would suggest you get a 1200 or 1400 psi output regulated tank from JDS Airman.... If you get a 13 CI tank you can mount it right on the gun.... If you decide to go with a remote tank and a line, then you can get whatever size tank you want, but again I wouldn't go more than 1400 psi and make SURE you have a 1.8K burst disc on the output side of the regulator for safety.... If you go with a remote tank, instead of the QB79 style tank block you can use the fill fitting c/w male Foster from a Disco.... Make sure that you use hoses and fittings that are rated for the pressures you will be running.... If you choose 1200 psi, you can get away with the stock hammer spring and fine tune it with an RVA (power adjuster).... If you go 1400 psi, then use a 13XX hammer spring, again with an RVA.... If you use a 1500-1600 psi tank, then you will need a Disco hammer spring with an RVA.... Tuning the hammer is the key to good performance while keeping a decent shot count....Bob
Bob is a very informative fellow. He (as are many others) is a great asset to the gta!
