## Overview

This 10-pack of 8g CO2 cartridges, including one oil-infused cartridge, is engineered for Byrna SD, CL, HD, and EP models. Each cartridge delivers 15-20 rounds of consistent power, while the oil cartridge ensures smooth maintenance every 5th use, extending your device’s performance and reliability.

## Description

Our box of ten 8g CO2 cartridges are custom fit for the Byrna HD. Now including 1 CO2 cartridge with oil for simple maintenance every 10 CO2 cartridges used. Each cartridge (new) will be good for 15-20 rounds (4 mags in a 5 round magazine) at full speed. Punctured cartridges within the Byrna HD will leak over time. 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: They work fine but being proprietary they overpriced them, of course.
Review: These work great in our Byrna. However, desertcart packed the box of these absolutely loose in a bigger box with some other things. Not sure how this is safe with them tumbling around in there? But desertcart has been packing and shipping most of my items like this for a while now— no real consideration of what the items are.

## Features

- WHAT'S IN THE BOX: (10 ct.) 8g CO2 Cartridges. Including 9 standard 8g CO2 cartridges and 1 CO2 cartridge including oil for maintenance.
- EASY TO USE: Simply install the oiler cartridge like any other 8g CO2 cartridge and fire away! The CO2 with Oil cartridge does all the work while you fire.
- * PLEASE NOTE: This pack of CO2 cartridges includes one marked cartridge that contains CO2 + Oil. We recommended using this CO2 + Oil cartridge every 5th cartridge to maintain lubrication and optimal performance. The oil cartridge is not always labeled and is placed in the box facing the opposite direction as the other 9 cylinders. The oiler cartridge can be used just the same as the other CO2 cartridges.
- COMPATIBILITY: 8 Gram CO2 Cylinders are compatible with the Byrna SD / CL / EP & HD Models.
- Not compatible with Byrna LE, SDXL, HDXL or Launchers with Byrna Boost Installed.

## Questions & Answers

**Q: No byrna 8gr cartridges available, can I use a different brand 8 gr?**
A: According to Byrna, No you can't because non Byrna manufactured CO2 cartridges can damage and void your warranty. That being said, I see a lot of LTL who own Byrna launchers using off brand CO2 so it's up to you. 
Also Byrna says to oil your launcher after every 500 rounds, so if you have the oil cartridge, you don't need to use it after every 9 cartages, you can save them for when you've gone through 70-75 reloads (5 round clip) then you'll be getting closer to the 500 round recommendation.

**Q: How do I know wich one is the oiler? All of mine came the exact same way.**
A: mine was marked with a dot on it,, can't remember what color dot,, all i know is that it had a dot on it,, but,, the only way you'll know now is when you fire it,,

**Q: Will 12 gram cartridges fit in the gun**
A: No, you have to buy the 12 gram adapter from Byrna then they will fit.
