Why Does One Byrna CO2 Cartridge Say "Oil"? A Simple Guide to Launcher Maintenance

Keeping a Byrna launcher in top working condition doesn't require complicated maintenance. One of the easiest ways to care for a launcher is by using the specially marked oil CO2 cartridge included in every 10-count box of Byrna CO2 cartridges.

If you've ever wondered why one cartridge is labeled "Oil," here's everything you need to know.

What Is the Byrna Oil CO2 Cartridge?

Every 10-pack of Byrna CO2 cartridges includes one cartridge marked "Oil." This cartridge is designed to lubricate the internal components of the launcher during normal operation.

Instead of requiring users to disassemble the launcher for routine lubrication, the oil cartridge distributes lubricant throughout the internal system while the launcher is fired. This simple process helps maintain reliable performance and extends the life of internal seals and moving parts.

When Should the Oil Cartridge Be Used?

Byrna recommends using the oil cartridge as part of a regular maintenance routine while working through each 10-pack of CO2 cartridges.

Many owners choose to use the oil cartridge during a training session, allowing the lubricant to circulate naturally while practicing. This makes routine maintenance quick, convenient, and easy to remember.

How to Use the Oil CO2 Cartridge

Before inserting the oil cartridge, always ensure the launcher is completely unloaded. Remove the magazine, verify there are no projectiles in the chamber, and point the launcher in a safe direction.

The oil cartridge is installed exactly like a standard CO2 cartridge. It delivers the same number of shots and comparable performance while simultaneously lubricating the launcher's internal components.

After the cartridge has been used, replace it with a fresh, unpierced CO2 cartridge so the launcher remains ready for everyday carry or home defense.

Simple Maintenance for Long-Term Performance

Routine maintenance doesn't have to be complicated. The Byrna oil CO2 cartridge makes it easy to keep a launcher operating smoothly without disassembly or specialized tools.

Combined with regular training and proper storage, this simple maintenance step helps ensure a Byrna launcher is always ready when it's needed most.
