Something I didn't see referenced in this thread and I believe explains the CO2 working issue. CO2 and most other propelants are regulated gasses so they are stepped down to a safe pressure. IE say CO2 produced 1800psi(I don't even know if this is in the ballpark)@80 degrees F and you regulate it down to 70-80psi(near greengas if I recall) then even at extreme cold temps your native pressure shouldn't drop far enough to make a noticeable change in pressure. So lets say a freezing CO2 puts out 300psi, it's still going to be regulated down to 70-80psi so it's of no consequence what temp it is untill the pressure drops below what it's regulated to. The only thing I can think of that would change this is if the CO2 would work less efficiently such as releasing a slightly heavier mixture of liquid and gas causing you to get less shots per mag though on that topic I'm not sure.

I don't think most people use CO2 regulators on their airsoft guns, and if they did, I'd make sure I had a premium quality regulator before playing in the winter. CO2 cools as it evaporates, and if you use too much too fast, you can freeze your regulator and choke off the flow. In the paintball world this is a problem year round because fast-firing markers can chew through so much CO2. Airsoft guns are thrifty by comparison, but at 40 degrees it takes a lot less to freeze the reg than it does at 90. In most cases, getting a shot of liquid CO2 into a regulator will freeze it almost instantly.
Absent a regulator, CO2 pressure is controlled by the evaporation of liquid CO2 into gas, and is therefore determined largely by ambient temperature. Even in the winter, you're probably looking at pressures around 350-500psi (and if it's too cold to hit 300 psi, go inside, jackass!). Given appropriate valve design, 350 psi can be more than ample for any airsoft use.

So CO2 is actually around 300 psi? I guess I show my ignorance on the topic;) I was reading about an M700 conversion and most of the CO2 handguns I've seen have been either green gas or CO2 which to me meant they used a regulator of sorts or it would seem they would go far to high as far as velocity. Like I said I may be off base there, but that was what it seemed to be.

It's temperature dependent. If you're playing in the dead of winter and it's 15 degrees Farenheit, yeah, your CO2 is in the 200-300 range. In summertime it's usually 800-1000psi. Remember that it's not just pressure but also the amount of gas released that matters - with the right valving, you could feed your gbb pure CO2 at 1200psi and still shoot 280. However, the only CO2 guns I've ever seen chrono'd were indeed shooting hot. Phase-change propellants (green gas, 134, CO2) are often used for compact applications because their evaporation keeps the pressure somewhat stable, allowing the user to dispense with a regulator. The propellants that have to be regulated are those that follow the ideal gas law, since otherwise their pressure would decline steadily with every shot. Munin learned this the hard way when he tried putting compressed in a GBB mag. Our paintball brethren explain it all at www.warpig.com/paintball/technical/gasses/co2dynamics.shtml

Also, gas guns lower in FPS by quite a lot in winter, and if melted snow gets into the internals, it could seriously fuck up your gun. Also, don't use them when its raining, because the internals malfunction. I myself have a HFC Mauser Gas Sniper Rifle, and it's very powerful and accurate AS LONG AS you play when no precipitation is occuring. I enjoy it very profusely, but in my opinion, just get yourself and good AEG or springer.

alright i will be exerimenting coming up soon with handwarmes. Actually the foldable thin body warmers. I will be storing the mag from my gun in my pocket, and will wrap the warmer around the handle of my SOCOM. when i need to use it, i will shoot like normal and see if there are any significent improvements
**note i will wait a little for the gas to warm up [if im not under fire] and i will not leave it on too long that it explodes the mag

the handwarmers do work great for keeping your gas and gun warm i use them every game. you can get them at pretty much every store and there very inexpensive.

Uh, I never saw him say that they didn't. The point remains that even CO2 does not work as well in the cold. See Zorak's post about freezing regulators in a previous post. Additionally, as someone who used to play paintball in pretty much all weather conditions, I can tell you for sure that you get a lot fewer shots out of a 12-gram CO2 powerlet in the cold than you do when it's nice and warm and sunny out.

C'mon man, you double posted in a thread that hasn't had any activity in almost 8 months. Please try to modify posts in the future, and please don't necropost. It can tend to get on people's nerves.
Edit- Mods, sorry if I'm stepping on anyone's toes. I tend to have chunks of free time at work, and usually occupy myself on the forum.

HotCarl, you forgot to mention that he is full of crap as well. CO2, most popularly used by paintballers, has a significant decrease in power/effectiveness in the winter, hence, the introduction of compressed air units. Also, something cute to think about, he promises here to fix his spelling etc (while messing up spelling there... LOVE the Spell Check!!) Sorry, about that it was indede my first message, and i will try to keep my spelling in its place. thank you for the tips. So I'll just fix his next two for him, maybe he'll read them and get a clue, all the changes are underlined.... Yea, green gas and red gas do freeze in winter but if you were going to play I suggest a Co2 powered gun. Also, I am pretty sure that Co2 doesn't act up in winter. For one reason Co2 is colder than it will probably get out side so I'm almost sure it will not mess with the firing range. But using your gun in the winter isn't the best thing you can do. 17 Errors in 4 sentences, not to mention the 3 in his post promising to fix his spelling. Loving it!

Well, I was gonna over look that since the posts at the top of the page seemed to contra-indicate what he said.

And you know what tex I'm too lazy to spell a full word out. Please mock me. probably fuckin 40 years old and u live with your fucking mother, I think i'm retarded. doy! if you havent noticed no one likes I'm too lazy to spell a full word out. Please mock me. fuckin faget ass Actually Tex is 21 and I have played a few games with him. He is a cool guy who goes out of his way to help other players with what they need, i.e. a loaner pistol, fix their gun, and other stuff. If you just took an extra minute, (you dont even need that much time), to reveiw your post before you hit submit, then people would not get on you about it. Also, before you post, you should do a little bit of research, because Co2 loses as much if not more power than green gas, red gas, or propane. P.S. The modify button is in the upper right-hand corner of the post, please use that instead of double posting.
