Will these fit my airsoft pistol?

They are standard 12g CO2 capsules, so they fit any airsoft gun, air pistol or BB gun that takes 12-gram cartridges. Check your gun's manual to confirm it uses 12g CO2 rather than green gas.

How many shots does one cartridge give?

That depends on the gun. A CO2 pistol typically gets several dozen shots per capsule, while rifles vary widely. Cold weather reduces the count noticeably.

Can I leave a cartridge in the gun between sessions?

It is better to remove it and fire the gun empty of gas. A pierced capsule left in place can leak or damage seals over time.

Are these refillable?

No. They are single-use capsules and should be recycled or disposed of according to local rules once empty.

Do they work in cold weather?

They work, but CO2 pressure drops as temperature falls, so velocity and shot count fall too. Keep capsules warm until use for better performance.

Fifteen 12g CO2 cartridges, each sealed for single use.

Our take on the JT 12gram CO2 Cartridges - 15ct

JT 12g CO2 cartridges are single-use powerlets for airsoft guns, air pistols and BB guns that take standard 12-gram capsules. Each cartridge is filled with CO2 and sealed for leak-free storage, and the 15-count pack covers a long run of shooting sessions. They are the generic consumable rather than a precision part, so performance depends mostly on the gun's valve and seal. Compared with unbranded bulk capsules, JT leans on quality control and consistent fill weight; shooters who chronograph their guns often note that CO2 output varies with temperature more than with brand.

What reviewers say
