Byrna Common Issues and Fixes

Summary

Most Byrna launcher issues can be resolved quickly with a few simple checks. The majority of problems come down to CO2 cylinders, projectiles, or basic maintenance.

Quick Answer

If your Byrna isn’t performing correctly, start with these steps:

• Check that the CO2 cylinder installation instructions were followed exactly
• Confirm that a new, unpunctured CO2 cylinder has been installed
• Confirm projectiles are in good condition

Common Issues and Fixes

Low Power
If the launcher feels weak or underpowered, the most likely cause is the CO2 cylinder.

• Replace with a fresh CO2 cylinder
• Performance will drop when cylinder is nearing empty

Not Firing
If the trigger is pulled but nothing happens:

• Check that the CO2 cylinder is new, unpunctured, and installed correctly
• Verify the safety is in FIRE mode (if equipped with an external safety)
• Ensure the trigger is being fully depressed to the rear

Jamming
Feeding issues usually relate to the projectiles or magazine.

• Confirm the magazine is seated properly
• Inspect projectiles for damage or deformation
• Ensure that you are using the correct caliber projectiles
• Avoid using old or improperly stored rounds
• Many 3rd party projectiles can cause jamming
• Ensure that a "plus one" setup is not being used

CO2 Leaking
A leaking cylinder will reduce performance quickly.

• Check that the proper CO2 Installation instructions were followed

Maintenance Tips

Consistent maintenance prevents most issues before they start:

• Keep the launcher clean and free of debris
• Use oiler CO2 cylinders or oiler kit once every 3-6 months or every 10 CO2 cylinders to maintain seals
• Store the launcher and projectiles in a cool, dry place
• Customers should NEVER attempt to disassemble or repair and launcher on their own
• Customers should fill out an RMA request for service if they are unable to resolve an issue by following the troubleshooting steps. 

Key Takeaway

Proper CO2 use, good projectile care, and routine oiling will keep your launcher running reliably.
