Frequently Asked Questions

Will these 12g CO2 cylinders work with my airgun?

Yes, if your airgun has a standard neck air port. These 12-gram cartridges fit Sig Sauer airguns and most other brands that use the universal standard port. Check your airgun's manual or port design to confirm compatibility.

How long does a 12g CO2 cartridge last?

That depends on your airgun model, the power level you're running, and how much you shoot. We don't have specific shot counts from Sig, so check your airgun's documentation or manufacturer specs for expected performance per cartridge.

Why buy the 40-pack instead of individual cylinders?

Bulk packs save trips to the store and keep you supplied for extended range sessions or competitions. If you shoot regularly, you'll go through CO2 steadily—the 40-pack eliminates the frustration of running out mid-session.

Are these pre-filled or do I fill them myself?

These are pre-filled 12-gram CO2 cartridges. You insert them into your airgun's CO2 port directly—no filling required.
