Designed exclusively for Byrna launchers with the Boost 12g adaptor, each cartridge supports up to 30 rounds, ensuring consistent, full-strength shots without leaks or misfires.

BYRNA 12G CO2 CARTRIDGES INCREASE SHOT CAPACITY TO 30 ROUNDS PER CARTRIDGE. It is recommended to swap out punctured CO2 cartridges and leave an un-punctured cartridge inside the Byrna HD to avoid any compressed air loss. The Byrna HD will puncture and fire the first round at the same time. Review: 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. Review: Very well made. ## Features - WHAT'S IN THE BOX: (10 ct.) 12g CO2 Cartridges. Including 9 standard 12g CO2 cartridges and 1 CO2 cartridge including oil for maintenance. - EASY TO USE: Simply install the oiler cartridge like any other 12g CO2 cartridge and fire away! The CO2 with Oil cartridge does all the work while you fire. - COMPATIBILITY: Byrna 12g CO2 cartridges are custom fit for the Byrna TCR / LE / SDXL / HDXL or launchers with the Byrna boost 12g adaptor installed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09C345NZ4 | | Air Gun Power Type | CO2 | | Brand Name | Byrna | | Caliber | 0.68 | | Color | Silver | | Cross Section Shape | Round | | Customer Reviews | 4.7 4.7 out of 5 stars (579) | | Global Trade Identification Number | 00810042111011 | | Item Weight | 12 Grams | | Manufacturer | Byrna | | Manufacturer Part Number | CO2330 | | Material Type | Aluminum | | Shape | Round | | Sport Type | Airsoft, Paintball, Target Shooting | | Style Name | Classic | | UPC | 810042111011 | ## Product Details - **Brand:** Byrna - **Colour:** Silver - **Material:** Aluminum - **Sport:** Airsoft, Paintball, Target Shooting - **Style:** Classic ## Images ![CO2 12 Gram Cartridges 10-pk CO2330 - Image 1](https://m.media-amazon.com/images/I/81XD9TMqujL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***C on 8 February 2026* These official Byrna cartridges (9 plain CO2 + 1 oiler) are the only ones I trust in my Byrna SD/LE.
