Byrna LE Gen 2 Troubleshooting Guide

Summary

This guide helps identify and resolve the most common Byrna LE Gen 2 issues so you can quickly restore proper function and performance.

Overview

The Byrna LE Gen 2 is built for reliable performance, but issues can occur due to setup, handling, or component choices. Most problems such as failure to fire, CO2 issues, low power, or jamming are easy to resolve with proper troubleshooting steps.

Common Issues and Fixes

Not Firing

If the launcher does not fire, check the following:

1. Safety Lever

• Ensure the safety is disengaged
• The launcher will not fire if the safety is on

2. Trigger Operation

• Pull the trigger all the way back
• Partial trigger pulls will prevent firing

3. CO2 Cylinder

• Confirm the CO2 cylinder is installed and not empty
• Replace with a new cylinder if needed

CO2 Not Puncturing

If the CO2 cylinder does not puncture, review these causes:

1. Installation Issue

• Push the CO2 cylinder in firmly before tightening the cap
• Tighten the cap until snug
• Avoid overtightening, which can affect performance

2. Trigger Not Fully Depressed

• The trigger must be pulled completely back to puncture the cylinder

3. CO2 Cylinder Brand

• Some brands may not puncture consistently
• Crosman CO2 cylinders are not recommended due to variability

Low Power

If shots are weak or inconsistent:

• The CO2 cylinder is likely running low
• Replace it with a new cylinder

Low pressure reduces velocity and overall performance.

Jamming Issues

If the launcher jams, check the following:

1. Overloaded Magazine

• Avoid 5+1 loading
• Extra projectiles can restrict movement and cause jams

2. Aftermarket Projectiles

• Non-Byrna projectiles may be improperly sized or out of round
• This can lead to blockages in the barrel

FAQs

Why is my Byrna LE Gen 2 not firing?
Most commonly due to the safety being engaged, incomplete trigger pull, or an empty CO2 cylinder.

Why is my CO2 cylinder not puncturing?
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 low and should be replaced.

Why is my launcher jamming?
Usually caused by overloading the magazine or using non-approved projectiles.

Can I use any CO2 cylinder?
Only approved cylinders are recommended. Some brands may not perform consistently.
