Has anyone thought or implement off-gun tank idea?
There are relatively cheap 3000-4500PSI carbon fibre tanks available with capacity upto 110ci. You could wrap the tank on your backback and use standard sprial-hose to feed the gun. Then make a nice perfect stock without bottle dimensions compromising anything. Have an accurate and adjustable separate regulator with pressure gauge both for tank and requlated pressure. Also reduce the weight of the gun a lot. The pros-list is endless. The only con is to carry the lighweight bottle on the back and have it separated from the gun.
I just can’t stop thinking about the shotcount with 110ci and 4500PSI. And the POWER and consitency with regulated pressure. Maybe about 150+ 60FPE consistent shots.
Or maybe the carbon fibre (AL core) tank could handle the hammer slap and you could also use it inline in the gun as regular bottle?
Our local dealer sells standard PaintBall AL-bottle (800ccm & 200bar = 3000Psi) for 40â‚¬. Thats about 60$. I think I will get one and try it out for my valve project.

I have done this with another rifle and it works very well. There are several types of remotes that you can get. It was not a Talon that I did it on so I am not sure how you would get the valve to interface with the remote but I am sure that there is someone here who can figure it out. However most paintball regulators only run 850-900psi on the output side.September 24, 2007 at 9:29 pm #24839
I have a couple of those tanks and here is the catch. Those tanks are regulated down to around 850 psi and some down to 450 psi.
If you do run a remote line to it will give you velocity similar to the CO2 set up at those pressures.September 25, 2007 at 4:11 am #24848quote minkling:
Thx. Good to know.
I was not thinking about using paintball regulator but my own. And I have been told that on some PB regs you can just change the springdiscs for different output.
My idea was only use the PB carbon fibre tank (4500PSI & 1.5Litres). I would just put bottlevalve and carrying back or beltstrap in it. Then run a spiral hose to the gun which has ergonomic custom stock. The stock attach to the gun with same thread than standard tank. Inside the stock there are regulator, big enaugh regulator chamber (50 ccm or so), two small gauges. One for tank and another for regulated pressure, regulator power adjustment wheel. Also on the frontend there would be “standard” hiflow firing valve.
And this is not meant to be permanent. Just another option for longer hunting trips. You could still change the standard bottle+valve back anytime.
Adam; Do you mean that the regulator is permanently attached to the tank? You can take it away can’t you?
There was a nice compromise also. 0.7Litres & 300bar carbonfibre tank which has excellent dimensions. 80mm diameter and 240mm length. That’s just little bigger OD than standard tank but it’s 50mm shorter (for those who think std tank is too long). If you’d use FT-style adjustable buttstock with it you would have “best on both worlds” and even some space left for regulated mainvalve and chamber (and gauge :D).September 25, 2007 at 4:34 am #24850
Yes you can take the reg off the tank. But here is the problem. It will be very risky having 3000psi running through a hose. First you will have to find a hose that can hold that pressure and it probably will not be very flexible. Next you will have to be cautious getting it caught on a branch and having it come off the fittings.
I have had a hose get loose while filling and it is a painful and scary event. A loose hose can do some damage. I only use a direct connect now.September 25, 2007 at 5:06 am #24854quote Adam in SoCal:
I hear you Adam but then again..
This is standard 3000 PSI flexible hose used for PaintBall remote’s. If they can run, jump, crawl and play war with it I would think that you could also _walk_ in the forest without problems.
But I do understand your worry and cautions. I wouldn’t want to have loose hose either with full 1.5L tank. It can be made more safe if there is a very small hole on the tank side. Say sub millimeter (still big enaugh to feed the regulator chamber during shots). With that small hole the violence of possible hose break is less extreme.September 25, 2007 at 2:13 pm #24865
That remote is only rated for 850PSI from the tank regulator not the full tank pressure.September 25, 2007 at 2:21 pm #24868
I a pretty sure that hose is not rated that high. I have had a couple of those for paintball and it is used on CO2 or HPA regulated down to 850 psi.
Worth checking out. No paintball guns run off of 3000 psi.September 25, 2007 at 2:57 pm #24870quote minkling:
That is possible but the site says for that hose: “Coil remote kit 3000psi”.
Could be a mistake or misunderstanding. Thanks for pointing out.September 25, 2007 at 3:40 pm #24872quote mcMike:
I looked that hose up and you are right one I found even says it holds up to 5000psi. Now I hope that is true and not just a selling point for them. Even if he hose is able to hold 3000psi I wonder if the fittings are able to. I would take that hose to a hose store and have them check the fittings to make sure it is truly rated at 3000+ psi.September 25, 2007 at 4:57 pm #24874
Maybe they rate it that high just in case you had a regulator failure and full tank pressure made it into the line. I agree though that I would verify the fittings etc. I was present when a line went while refilling a 5000psi Large Compressed Air cylinder. The operator was very lucky that all that was hurt was his shirt and sunglasses. The whipping line grazed his shirt and ripped the sunglasses out of his pocket and threw them across the room.September 25, 2007 at 5:02 pm #24875quote minkling:September 25, 2007 at 5:03 pm #24876quote minkling:
I have had that happen. Fitting failed and hose whip and put a hole into the interior of my van. At the paintball field they had to strap the hoses down to a table because of a fitting failing and whacking a customer hard in the face.September 25, 2007 at 5:04 pm #24877quote minkling:

I think that the secret is to find out what the Big Bore bench shooters use, as I’ve seen many of those with DAQs and Barnes etc sitting down with a scuba and a hose to the front of the rifle.
