Anyone use Gauntlet .25 with CO2 bottle?
- Thread starter leon79705
- Start date
I haven't tried CO2 on my Gauntlet .25, but I have used it on a similar gun in .25 caliber, but with a shorter 18..5" barrel. JSB .25s ran 650fps around 70 degrees.
A word of caution... make sure you have spare o-rings on hand prior to charging with CO2. It may take months or it may take as little as days, but you will need them.

CO2 won't provide enough pressure to push the .25 Gauntlet effectively. IIRC CO2 hits about 850 psi at 70 F.

I finally have a chance to use Co2 with the Gauntlet .25. It was pushing the Benjamin 27.9 grain pellet 570 fps.

At 90F, CO2 runs about 1100 psi so that gives you an idea how CO2 performs vs the Gauntlet's 1900 psi factory air reg setting. Don't be surprised if you start seeing burst disc ruptures at warmer temps, especially if out in the sunlight.

If it's hard to believe it....ask the paintball crowd that have left black spare cylinders in the sun on hot days.

Most paintball tank disc setups are rated 3K for CO2 and 5K or 7.5K for air on the tank side and I believe 1.8K on the regulated side if it's a 2 disc regulator. Ever sit on a black vinyl seat in the sun or grab a black object that's been in the sun and have to drop it? IIRC, CO2 hits 3000 psi at 155F which can be achieved on hot days with black tanks and keep in mind that many discs will burst below their rating. These specs are from memory so take it with that in mind.
