Which CO2 Cylinder Should I Use for My Byrna Launcher?

Choosing the correct CO2 cylinder is essential for getting the best performance from your Byrna launcher. Using the right size and brand ensures proper puncturing, consistent pressure, and reliable operation every time.

Summary

• Use the correct CO2 size for your specific Byrna model
• 8g cylinders must be Byrna-branded
• Most standard 12g cylinders work
• Avoid Crosman 12g cylinders due to puncturing issues

CO2 Cylinder Compatibility by Model 

8 Gram CO2 Cylinders

The following Byrna launchers use 8g CO2 cylinders:

• Byrna HD
• Byrna SD
• Byrna EP
• Byrna CL

Important:
Only Byrna 8g CO2 cylinders should be used with these models.

Unlike 12g cylinders, 8g cylinders are not standardized. Many aftermarket options will not puncture correctly or fit properly inside the launcher.

Using non-Byrna 8g cylinders may cause:

• Failure to puncture
• Inconsistent pressure
• Reduced or no firing capability

12 Gram CO2 Cylinders

The following models use 12g CO2 cylinders:

• Byrna LE
• Byrna LE Gen 2
• Byrna SDXL
• Byrna CLXL

Most standard 12g CO2 cylinders are compatible with these launchers because they follow a more uniform industry design.

However, not all brands perform equally.

Note:
Crosman 12g CO2 cylinders are not recommended, as they may have inconsistent puncturing in Byrna launchers.

Common Issues from Using the Wrong Cylinder 

Using the incorrect CO2 cylinder can lead to several problems:

• The cylinder does not puncture
• Low power or weak shots
• Inconsistent firing performance
• Complete failure to operate

For the most reliable performance, always use Byrna-approved CO2 cylinders and confirm compatibility with your specific model.
