I'm filling up "refillable" Co2 capsules and airsoft Co2 shotgun shells. Sadly ALL local shops have stopped filling Co2 bottles.
Mailing any pressure-canister in this country can lead to it being seized and destroyed. And anything other they just utterly destroy.

Anyways. Sodastream is quite affordable option and most big markets sell em.

Now i just need the adapter. I bought one adverticing it was for paintball but it was wrong threading to my fill-adapter, it did fit the SS-bottle. HPA and Paintball Co2 bottles fit my fill-adapter.

Just about every country has their own "term" for the threading on both ends so i have no idea what i should be going for...
The one with the wrong threading cost sub 10 bucks so around that price-range would be awasum.

So please, help out a n00bie here, link me an adapter with the right threading. Ebay, Ali, or an EU retailer.

Oh noes...

Plan B.

What are the threads of the Co2 bottle called? As in, size. I'l try to look for an adapter using that.

My recommendation would be to skip the sodastream entirely and get a commercial co2 bottle from a welding gas supplier, and they will also have the right fittings to attach your fill station to it.
I like the smaller bottles like they use for soda machines, in the US they are the aluminum 20 pound trade size not sure the equivalent over there, but they are usually portable with a convenient handle.
This will last longer, be cheaper per fill, not waste as much gas as when the tank gets low, etc.

This,

2 things though, you need to make sure the tank has a siphon tube installed so you are getting co2 LIQUID into your paintball tank. Sometimes they are called "dip tubes"

Or, if you get one of the smaller tanks you can just flip it upside down to accomplish the same thing

You will still need a co2 fill station which, chances are will run you around $50-70 and a scale for weighing your tanks

All told, you are probably looking at a price range around a decent HPA taco before you can get co2 into one of your bottles so I have to ask, is there any reason you are sticking with co2 over switching to HPA?

Your question has been pretty much answered by ke6gwf and TrBo. I have actually done what you want to do. First forget the SodaStream as it is designed for gas distribution, not liquid. A CO₂ paintball bottle is filled with liquid. Filling with CO₂ gas might get you 6 to 10 shots.

But, you can buy a scuba size tank that can be filled with liguified CO₂. You buy that tank at a welding supply outfit. This is what is called a 20 lb tank and will cost you about $135 for the standard tank and $160 for the dip tube tank. Either will cost you about $36 to fill again once you have used them up.

Filling you paint gun bottles: You do not need a filling station, but you are going to have to put together the fittings and hoses to transfer liquid from the 20 lb tank to the bottle used on the PB gun. If you don't know about pipe threads and fittings or have someone to help you, you may be up the creek. The welding shop may consider your need of help to adapt the transfer as a risk since you don't have the knowledge to handle pressure tanks.

Now, there used to be available single braided hoses that you could buy online and even Ebay that screwed directly from the 20 pounder to your PB bottle. There is no regulator needed. In fact you do not need a siphon bottle.

Make a frame to hold the bottle upside-down to feed the liquid CO₂. Attach the hose between the 20 lb and the PB bottle and open the 20 lb valve. You will usually hear it flow. When the flow stops, leave the valve open for 5 to 10 minutes to assure a full fill, the cut off the 20 lb tank valve then detach the bottle. Realize the PB bottle has a pin valve much like the style of a bicycle tire, so the bottle vents no gas, but the connecting line may. Some of those hoses had a small bleed valve to vent the gas in the line.

Yes, it is less expensive to fill your own. . .after you have absorbed the cost of the tank and related parts. But, if this is more complicated that you want to mess with, I may have a solution. Most welding supply facilities that supply welding gasses that refill that 20 pounder CO₂ cylinders will refill your PB tank for around $5 to $6. If you are in San Diego, try Stoody Industrial & Welding Supply. Those prices I quoted are from their web site.

Also, many businesses that service restaurants that have fountain soft drinks are handling CO₂ systems and locally where I live would fill my PB CO₂ tanks (but it has been a while since I used a restaurant service, so you'll have to look).

The methods described here are very dangerous and should not be used to fill paintball tanks

you need to weigh your tanks, that's the only way to get the proper amount of co2 into each tank. Leaving the tanks connected and open for 10 minutes is a easy way to over fill a tank. This can easily lead to a burst disk on your tank rupturing, the tank emptying it's contents on anything nearby and you then needing to buy parts to fix it

Bruce says to not buy a fill station but then goes on to describe basically making your own. Just get a fill station, they are made by professionals and make your life much easier. You need to have at least 2 valves. One to control your bulk tank and one to bleed your line. The bleed is important because you can also chill your paintball tank using it
