CO2 12 Gram Cartridges 10-pk CO2330

These official Byrna cartridges (9 plain CO2 + 1 oiler) are the only ones I trust in my Byrna SD/LE. Generic 12g cans might save a few bucks, but they’ll give you misfires, leaks, or a sad half-powered shot when you really need full “please leave my house” velocity. This pack keeps your launcher fed and lubricated like a responsible adult. Pros: • Pierces clean every single time – no duds, no weak pops, full power shots • That one oiler cartridge is genius – drop it in every 10th mag or so and your pierce pin stays slick (no more sticky valve drama) • Perfect seal with Byrna magazines – no frostbite leaks down your hand • 10-pack lasts a good training session or gives peace-of-mind spares for the range bag • Official Byrna = no warranty worries if something goes wrong Cons: • Costs more than Crosman bulk packs (but you get what you pay for) • Still single-use CO2 – you’ll burn through them practicing (worth it though) • The oiler smells a little like silicone lube – your launcher will smell faintly like a tire shop for a day Bottom line: If you cheap out on CO2 with Byrna, you’re basically bringing a half-charged phone to a gunfight. This pack keeps your launcher happy, reliable, and ready to ruin someone’s day (non-lethally). 5 stars – buy these and stop gambling with off-brand gas.

Very well made.

Worked great in my Byrna LE launcher.

This is a must have. Good price highly recommend.

No complaints here. They work as expected being a product designed and manufactured by the end-use device.
