TADAA!

It's...it's gone.

Sorry for the shiptost I'm just very excited for this build!

Looks slick.

Please tell us the dimensions and where to buy that tank

I wish I could be more helpful, but after a long time scouring the internet for tanks smaller than 13ci, I happened upon an eBay listing for this 8ci tank. I believe it was part of a batch of custom tanks made after some interest was gained amongst paintballers (you can find threads on various paintball forums where the possibility of small custom tank production is being discussed).

Here's the best commercial lead I was able to find (sold out):
Ripple Industries Ltd. - Maxtact - 9ci/3000psi HPA Tank

If anyone wants to find a tiny tank like this, I'd recommend asking around on paintball forums.

That's the solution to all HPA Sniper Problems! Love the Idea. How about the durability of the stock after you cut it into 2 pieces?

close to that would be this tank
4oz CO2 tank

I was worried about this, but I ended up diving in anyway. As it turned out, the structural integrity was essentially unchanged! I'm quite happy with how rigid it remains, even without the tank in place!

That's awesome too, and it will provide at least 5x the shots that the HPA variant would.

I think you mean CO2

I also picked up a HPA hand pump, so instead of buying more gas, I'll get a little work out filling the tank, heh.

No, I meant HPA. As in "The (4oz) CO2 tank will provide at least 5x the shots (that) the (9CI) HPA would"

I'm blind :doh:

 

[Cuervo]

I would love a tank like this yes please!!!!

 

[XxTimxX]

Is that a vsr stock you put that in? Also anyone else is the kjw m700 stock bigger than the vsr stock?

 

[MagicMarker]

Good luck on the hunt, Cuervo! I wish I could help more, but you just have to scour the internet for xCI HPA tanks where x is anything under 13.

Is that a vsr stock you put that in? Also anyone else is the kjw m700 stock bigger than the vsr stock?

It is- a JG BAR-10 stock, at least. Comparing to my Tanaka M40A1, the Tanaka is almost the same, but slightly bigger I would say.

for everyone looking for this tank.... https://www.magfedproshop.com/products/9citank?variant=15392168345686

I just ordered one, ill get back when i get it

MagicMarker, i really like how you installed the tank, can you show us more (if you still have it) or explain how you did it?

Thanks

Just in case it wasn't clear, that tank is 9CI and mine is 8, but I suspect it would still work- especially with a shorter tank regulator.
Also it says 'out of stock' when you arrive on the page, but the tank without an included regulator (use the drop-down) is in-stock for anyone after it!

But of course!
Here's the tank/tank-reg/adapter and all in an engaged state (the adapter screwed down into the tank reg) in the exact position it is in when inserted into the stock:

Exactly how far it goes into the stock/grip:

I used a metric frickton of teflon tape to get everything screwed in to create the desired angles, and in one stubborn case, some semi-permanent thread lock as well.
Actually those pictures are a few weeks old, but it's taken apart right now and will be through the weekend - also totally tearing down the regulators and potentially removing one - so if there's any specific pictures you wanted, just let me know!

 

[Budske]

Thats nice, thanks, yeah, my mistake, i forgot that you got the 8ci..... That 9ci tank is the smallest i could find and im getting it today.

It should be 7in long with the standard reg and using the storm regulator, it should be like 10in.

The problem im having (in my head because i havent stated cutting the stock) is how to make the hole in the grip... or maybe i can put the tank a little back so it start touching the butt plate instead of starting after it.

Ill take pictures or video of the process.

 

[MagicMarker]

Woops, forgot to say: My fully engaged unit is 9in/230mm tall.

Not sure I follow 100%, but a couple things:
On my BAR-10, the grip is an open cavity that directly transitions to the stock; I didn't need to add any holes per se, but I did have to ever-so-slightly increase the inner diameter down in the grip- I used an extension part with my Dremel.
And my tank is indeed up against my butt pad- just not cut into it.

I'll just take a bunch of pictures here in a bit and if there's anything specific I can help with, just let me know.

 

[Budske]

The vsr stock is not open to the grip, so you have to open it.

I have 2 JG Bar10 stock, the newer and the older version that is exactly as the vsr (better quality).

i think im going to use the newer version because it is easier to cut, it comes with the mag release with the top (that stop the spring from flying) and i already changed the sling mounts for quick release ones. Also, im going to use a push to connect fitting on the reg connected to a quick connect so it is easier to fit it in the stock instead of trying to fit the fixed QC in the reg on to the grip section

i will need an extension for my dremel, which one you got?

 

[MagicMarker]

I don't have much to compare it to, but my stock cuts quite easily with the following:
https://www.dremel.com/en_US/produc...ies/ez476-ez-lock-1-1-2-cut-off-wheels-5-pack
And also responds well to the sanding bits- makes a hell of a mess and can be almost too easy to remove material if you're not careful.
For inside the stock, I feel like you'd be better off simply drilling a hole the diameter necessary, however this is the extension tool I used:
