Byrna CL XL – Troubleshooting Guide

Summary

This troubleshooting guide helps identify and resolve the most common issues with the Byrna CL XL launcher. Following these steps can quickly restore proper function and performance.

Key Takeaways

• Ensure the trigger is fully depressed when firing
• Always use a new, properly installed CO2 cylinder
• Avoid over-tightening the CO2 cap
• Do not use aftermarket projectiles
• Avoid overloading the magazine (5+1 loading)

Not Firing

If your Byrna CL XL is not firing, follow these steps:

Step 1: Check Trigger Use

• Ensure you are pulling the trigger all the way back
• Partial trigger pulls will prevent the launcher from firing

Step 2: Check CO2 Cylinder

• Confirm the CO2 cylinder is new and not empty
• An empty cylinder will not provide the pressure needed to fire

CO2 Not Puncturing

If the CO2 cylinder is not puncturing, review the following:

1. Improper CO2 Installation

• Push the CO2 cylinder in firmly before installing the cap
• Tighten the CO2 cap until it is snug
• Do not overtighten, as this may cause trigger issues

2. Trigger Not Fully Depressed

• The trigger must be fully pulled back
• This action punctures the CO2 cylinder and pressurizes the launcher

3. CO2 Cylinder Brand Issues

• Some brands may not puncture reliably
• Byrna does not recommend Crosman CO2 cylinders due to inconsistent puncturing performance

Low Power Issues

If the launcher is firing with reduced power:

• The CO2 cylinder is likely nearly empty
• Replace it with a new CO2 cylinder

Low pressure can result in reduced velocity and inconsistent performance.

Jamming Issues

If your launcher is jamming, check the following:

1. Overloading the Magazine (5+1 Loading)

• Loading in a 5+1 configuration can cause jams
• The extra projectile prevents proper movement inside the magazine

2. Using Aftermarket Projectiles

• Non-Byrna projectiles may:
  • Be out of round
  • Be incorrectly sized
• This can cause projectiles to become lodged in the barrel

FAQs

Why is my Byrna CL XL not firing?
The most common reasons are not fully pulling the trigger or using an empty CO2 cylinder.

Why won’t my CO2 cylinder puncture?
This is typically caused by improper installation, not fully pulling the trigger, or using an incompatible CO2 brand.

Why is my launcher losing power?
The CO2 cylinder is likely running low and should be replaced.

Why is my launcher jamming?
Jams are usually caused by overloading the magazine or using aftermarket projectiles.

Can I use any brand of CO2 cylinders?
Byrna recommends using approved cylinders. Some brands, such as Crosman, may perform inconsistently.
