Byrna 8g vs 12g CO2: Key Differences

Summary

Byrna 8g and 12g CO2 cylinders differ mainly in size and launcher compatibility. Using the correct cylinder ensures proper function, safe operation, and consistent performance.

Key Takeaways

• The primary difference is size and compatibility
• 8g CO2 cylinders are smaller and used in select Byrna models
• 12g CO2 cylinders are larger and provide more shots per cylinder
• The two sizes are not interchangeable
• Always verify your launcher model before purchasing CO2

Overview

Byrna launchers use CO2 cylinders to generate the pressure needed to fire projectiles or kinetic rounds. Depending on the model, a Byrna launcher is specifically designed for either an 8 gram (8g) or a 12 gram (12g) CO2 cylinder.

While both serve the same function, they differ in physical size, gas capacity, and which models they are compatible with. Attempting to use the wrong cylinder size will result in improper fit and the launcher will not function.

Key Differences

1. Size and Capacity

8g CO2 Cylinders

• Smaller and more compact
• Shorter length
• Lower CO2 capacity
• Fewer shots per cylinder

12g CO2 Cylinders

• Larger and longer
• Higher CO2 capacity
• Provides more shots and longer use

2. Launcher Compatibility

8g CO2 Cylinders are used with:

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

12g CO2 Cylinders are used with:

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

Important Notes

• 8g and 12g cylinders are not interchangeable
• Using the wrong size can cause:
  • Failure to puncture the cylinder
  • Poor or inconsistent performance
  • Inability to operate the launcher
• Always check your launcher model before purchasing CO2 cylinders

FAQs

Can I use a 12g CO2 cylinder in an 8g launcher?
No. It will not fit or function properly.

Can I use an 8g CO2 cylinder in a 12g launcher?
No. It will not provide proper fit or sufficient pressure.

Which CO2 cylinder lasts longer?
12g cylinders last longer because they contain more CO2.

How do I know which CO2 my launcher uses?
Check your launcher model or refer to the compatibility list above.
