Frequently Asked Questions
- Which Byrna launchers are compatible with 8g CO₂ cartridges?
- Byrna 8g CO₂ cartridges are compatible with the Byrna SD, CL, EP, and HD launchers. They are NOT compatible with the Byrna LE, CL-XL, SDXL, HDXL, or any launcher with Byrna Boost installed — those models require 12g CO₂ cartridges.
- What is the oiler cartridge included in the 10-pack?
- The oiler cartridge is a specially formulated CO₂ cartridge that contains a small amount of lubricating oil. When used, it coats the internal seals and O-rings of your Byrna launcher, reducing wear and extending the life of your launcher. Byrna recommends using one oiler for every 10 standard CO₂ cartridges used.
- How many shots does one 8g CO₂ cartridge power?
- The number of shots per cartridge varies depending on temperature, launcher model, and conditions. Generally, one 8g cartridge powers multiple shots. Colder temperatures reduce CO₂ pressure and may reduce shot count.
- Should I keep a CO₂ cartridge in my launcher when not in use?
- Yes — Byrna recommends keeping an unpunctured CO₂ cartridge in your launcher at all times for instant readiness. Do not store a punctured cartridge long-term, as it will lose pressure and may damage seals.
- Are Byrna CO₂ cartridges legal in all states?
- Yes. Byrna 8g CO₂ cartridges ship to all 50 US states and are also Canada Approved. No special permits are required to purchase or possess CO₂ cartridges.
- Can I use third-party 8g CO₂ cartridges in my Byrna launcher?
- Byrna recommends using official Byrna CO₂ cartridges to ensure proper fit, consistent performance, and to avoid potential damage to your launcher's threading and seals.
