View Full Version : using HPA

I want to switch from CO2 to air with my MR1, do I need to get a regulator or any other upgrades to make my MR1 compatible with a HPA system?

nope, just slap the tank on and enjoy the better operation. Have you ever seen what co2 does to a marker, yuck.

oh yeah, I do suggest a remote, especially if you use the stock. It doesn't leave much room for your arm between the stock and tank.

ok thank you very much, I was worried that I would have to buy a regulator, and I dont currently have the cash to shell out for a reg and a air tank.

Is there a big difference between a 3000PSI and a 4500PSI tank as far as performance? And what about carbon fiber versus aluminum? Just the weight?

No performance difference at all. Just the number of shots you can get.

Carbon fiber is lighter, but you get the "cool" factor with it! Really, no difference other than weight and probably size - steel tanks can be a bit smaller...

I thought size was the CI (cubic inch) rating? PSI is a measurement of pressure not volume.

I think he is saying that although carbon is lighter than steel it's weaker so you need a thicker tank wall with carbon so it makes it bigger?

You still get more shots per PSI. The Cubic Inch (CI) is how big in volume the tank is, but the PSI is how much you can cram in there, so to speak.

For example - on a 68 CI / 3000 PSI tank, you multiply the CI by 10 and you get about 680 shots on average. However, on a 4500 PSI tank, you multiply by 15 which would give you an average of 1020 shots. (Those numbers are very low for todays standards, but you get the idea.) More CI and more PSI give you more shots.

Carbon fiber tends to need to be wrapped in layers over an inner "tank", thus making it a bit thicker than the standard steel tank, but much lighter due to the type of material used.

sure you can do that but here at the spyder forums we prohibit that if we find out you switched we will find you and make you buy more paintball stuff!!!:cool: :cool2: :evil: :busted: :darth:

Well thank you for clarifyin that Viking.

I just bought this tank since the tank I've had for a while now expired.


I thought it was a good deal since I dont have money for a carbon fiber tank.
