Switching to propane

[joker060]

How do you switch a CO2 pistol over to propane? If someone can just give me the basics it would help. Thanx.

Honestly I don't think it's possible without a lot of rebuilding the delivery system.

The C02, assuming its the small cartridge kind, have far too many differences from the propane. First off, just the housing for the gas is stored completely different and it'd be impossible to get those cartridges with propane in them.

Second, the feed for the gas into the firing chamber is different, so even just finding a gas mag that fits the mag well you would still need to completely mod the mag and the gun so that the gas can be delivered.

Third, CO2 has generally more power than propane because it compresses more does it not?



My question is which gun is it you are planning to mod? If this is one of those cheaper model Tippman guns on the lil cartridges, cut your losses and save for a real GBB.

I suggest the KSC G19 or the TM Hi-Cappa 5.1. The G19 upgraded is a sweet little pistol ((and I hate glocks!)) and the TM Hi-Cappa 5.1 stock is just phenomenal.

Well I was looking at getting a KWC Beretta and switching it over to propane becuause 1> its cheaper 2> I heard you get more power from propane.

...CO2 is like, several times the PSI of propane.

I used the same mag with both guns this way it can't be said that the two different mags had differences in the valves releassing different amounts of gas, and I did this in my basement at 22 degrees. I fired a few shots with each gun with each gas and took the average, and this is what I got as a result -

KJW MK1 NBB carbine -
duster - 303fps
green - 530fps
propane - 561fps

KJW MK 1 NBB pistol -
duster - 244fps
green - 391fps
propane - 393fps

The brands that I used were - duster - Falcon Dust Off, green - Jet, propane - Coleman. When using duster there is a massive drop off in fps, almost half, which seemed a bit on the odd side, but at least it brought my carbine down to field limits, and the gun itself is stock right out of the box, no aftermarket upgrades.

So is this info wrong??

There's nothing wrong with that info...

You need to ask yourself what that post has to do with CO2. It's not mentioned once in there.

Also, are you sure the KWC Beretta is a CO2 gun? You may be confusing some terminologies...

There are a few guns that are convertible, for ex the Sigma 40F, has both a CO2 Mag and propane mag available for it.
