I am trying to build my new sniper rifle as strong as possible and i have five main ways to power it, maybe some one could help me out!:

1. Soda club tank with regulator to fill the chamber
2.CO2 cylinders for bikes
3.N2O cylinders used for wipped cream
4.A tank with pressurized air
5.A hand pump

I need power, cheepness and safety, what of the above meathods should i choose? I am anxious to see all the responses i will get! If any one needs more details feel free to ask anything, if my requests are contradicting then give me a better idea or simply tell me which one of my meathods is best.

1 and 2) Soda Club tanks use CO2 IIRC, so it's going to be the same pressure, but for the Soda tank you'll need a $50 regulator (they're on special I think). For the small 12g or 16g CO2 cylinders, you just need one of those bike attachment things, the only problem is that the canisters are quite small.

3) I think that'll be similar to the Soda bottle, you'll need a regulator and a fitting that will work with the bottle and NPT threads.

4) How will you get the pressurized air though? Bike pump? Compressor? What will the tank be made out of? With this option, as long as the material is strong enough, you could use any of the other options to work with this. It's not really a source of power, you're getting another source of compressed gas and just transferring it.

5) This is a good option, if your chamber is small, you can get to 300psi in no time with a floor or shock pump.

Ok sorry for the missunderstanding but the number 4 was like bulk tank with compressed air it has a pressure of 200bar, but i think the regulator is expensive for that as well. Dont start with scuba tanks, they are very expensive and so are compressors. I can get bulk tanks with CO2 and air very easyly and cheeply and i have regulators for CO2. I hope this helps

200 BAR is pretty much 3000 PSI, so yeah it will be very expensive. Not to mention the tanks are usually quite big.

Compressors aren't expensive at all. You can get a decent 2hp one for about $70-$80USD if i'm not mistaken. But they're usually limited to below 150 PSI.

You could always get a fridge compressor.

OK I couldn't resist picking up the CO2 regulator kit for $49.99 (half price) at Lowes today while doing a little Black Friday shopping (for non-US guys, the day after Thanksgiving). Thanks Frank for the heads-up!



I was worried they would have been scarfed up as I got there late in the day, but they had 8 units on the shelf...one with my name on it.

.........Carry On.... 8)

For reference John, those were the regulators I was refering to that you'll need for CO2.

I'm tempted myself, but don't have the money.

Hey starman what is the max pressure?

I'll wager a guess at 120 psi, as that's what the gauge in the picture goes up to...

I have one of these.

Just a hint: Use Air cylinders, It SUCKS to use that reggy with CO2. the second you turn the thing sideways by accident it leaks CO2 into the thing, which then gets stuck in there, and leaks out a saftey valve, letting all of your CO2 out.

And the max pressure IS 120 PSI, A little low for my liking, but I was going to use it for pantball/airsoft cannons anyway.

Also, This reg is great for adding directly onto a cannon. If you take the plastic outer covering, It becomes an aluminum thing with three little things poking out at every 90 degrees, and one thing going off the side that adjusts pressure. You can remove all of these, Get an ASA adapter, Buy the 3/8 and 1/8 fittings that the pressure guage and Quick Disconnect go to (dont remove the Saftey Valve, The thing that looks like a funky plug), and build the reggy right into the gun. Its gorgeous.

Also, Its not the fastest Regulator. So dont expect your Golfball Cannon to fire one golf ball after another as fast as possible. For an airsoft gun with a Micro-Sized chamber and a long barrel (with target velocity at around 450 FPS) you will find it works great.

That is all. Wow that was a rant and 3/4.

Yep, 120 psi. Good for low and medium end PVC rifle and shotgun projects like Frank has been showing lately. Would work with bigger chamber guns as well but would just eat the CO2 like there's no tomorrow.

Also good for portable small air tools.

My first use for mine was blowing dust out of a 30 year old PA system

Oh man!. 8) That is a capital idea! I occasionally need to blow out computer and server gear all the time and I can never keep enough of the expensive canned air around. I would think you would want a flow regulator of some sort to use it that way.

My sound gear don't sit in one spot long enough to collect much dust so it stays fairly clean.

Nah, the blowgun that comes with the kit works perfectly fine.

Also, Im pretty sure you could modify that reg to give out higher pressure. I just opened mine up without much difficulty.

Or, you could simply buy a CO2 bottle with an anti-siphon tube. That way, no matter how you hold the tank you get nothing but gas out of the bottle.

The anti siphon only works when the tank is horizontal and facing a certain angle.
