What about CO2? A look at CO2 powered Airguns from a mostly PCP oriented audience. Article is from Pyramyd Air website.

I am confused with PCP and CO2-bulk powered AG. I seem to beleive these 2 designs are the same in principles and functions.
Can you elaborate more on this?
Thanks Gary

I have looked into one of the sites with assy drawings/parts of the 2 types of AG and it seems that they are very similar in construction. Also, the main idea of storing a compressed air by way of pump or CO2-bulk-scuba tank are found on both. So, are PCP and CO2-bulk powered AG the same?

So, are PCP and CO2-bulk powered AG the same? yes, same in design. just take note that PCP or Pre Charge Pneumatics handles 3000+ PSI as compared to lower pressure co2's. furthermore, transfer ports differ since air and co2 have different density.

bro saan ang malakas CO2 or PCP? pcp bro I agree, with very high working pressures on PCP guns, velocity as high as 900-1000 FPS or more may be obtained. In comparison to CO2's where the working pressure is just around 800PSI on a guns reservior which can manage around 650-750 FPS.

I am confused because I am using an Alloy tank with 3000psi on my AG and they call it CO2 tank. Therefore my AG is CO2 type? Or is it a PCP which takes power from the air (not CO2) from the 3000psi scuba tank?

Garyg,
You are really confused! But don't worry, I was like you before.
As Heightaddict and Snyper had said, the design of PCP and CO2-bulk filled airguns are the same. Some of the the differences in their designs are the sizes of their valves and transfer ports, weight of hammer and strength of the spring. In addition to that, the tank of the PCPs are a lot stronger, and most of the time, are bigger than those used in CO2s.
What differentiates a PCP from a CO2 airgun is the power plant, that is, the source of the airgun's power. An airgun designed for CO2 cannot use compressed air(the power source of PCPs) unless converted, because its tank cannot support its pressure. However, a PCP can use CO2 as a power plant, as long as the necessary conversion connectors are available.
In your case, the container (Alloy tank) of the CO2 cannot make your airgun a PCP even if it is capable of 5,000psi. Why? Because your power plant is CO2 and that your airgun's tank (tube) is not capable of handling such pressure. A PCP airgun is not a PCP airgun ,per se, if it is using CO2 as its power plant. Why? Because it is not using compressed air. ( PCP airguns give you options for your power plant.)
If my answer confused you more (I hope not!), you can try searching "airgun" in google. there are lots of information there.
As always, happy and safe shooting!

Now that you have mentioned that you are using an "Alloy brand tank". It would be correct for us to assume that it is a CO2 pygmy tank you use in filling your AG's reservoir with Co2. The 3000 psi rating is actually the tanks rating and not it fill pressure ( I used to think that way). The standard refills on pygmy tanks wont even reach that high. Unless you overfill that and expose the tank to extreme heat that's the only way you can make it rupture. Also, it would make it simpler for us to give you advice if you mentioned what gun brand you have. regards

Bro.,
Which one is more expensive PCP AG or Co2 AG? In Manila Area, what store sells PCP AGs?

PreCharge Pneumatic is a little bit expensive, compounded with the price for pump or scuba tank. then again, its just a one time investment since AIR is free, or about a 100 pesos per fill using a scuba tank. Armscor sells thru its stores nationwide.

Sir Heightaddict,
Can you fill us in for a price of an Amscor PCP AG, PCP tank and Scuba Tank? Here a .117 cal. Walther (Umarex) PCP AG costs 3300 Dirhams and Scuba Tank (Brand not asked) is about 1300 Dirhams. They sell both CO2 and PCP AG similar in construction only you see the PCP tank extending out in the receiver stock

I wish to raise this question....if the two AGs (CO2 n PCP) are same in principles yet differ in the powerplant. Is it possible to charge a CO2 AG with compressed air of 800psi - same pressure as CO2?
Kasi sayang din ang scuba tank compressed air left-over around 1500psi if not consumed totally since a PCP doesn't work well at that pressure. Then I guess a CO2 AG can be charged with compressed air with a limit pressure of 800psi.... Assuming that the CO2 AG has changed its air intake port like the one used by PCP AG. Also a CO2 AG will have a consistent firing since a compressed air density doesn't change in relation to the climate.

If you charge your CO2 AG with same pressure (800psi) you will have less shots than what you will normally get when CO2 is used. CO2 when liquid filled boils to gas when released and pressure is kept constant in relation to temperature. If you get 30 shots with CO2, you'll be lucky to get 5-6 usable shots with compressed air unless you use a remote line connecting your scuba tank IMO.

In actual experiment on an Armscor AG, you only get 3 shots. I'm no expert but the reason why you can have smaller air reservoir on CO2 AG is because CO2 is and expanding gas. On the other hand, A PCP needs a bigger reservoir for volume. Also if your PCP is designed to shoot at lower PSI then less then ok lang ang 1500psi.
