Compare the Byrna Loaded 8g and 12g CO2 carry cases. Learn which fits your launcher and how to pick the right one for your needs.
Quick answer
Choose the Loaded 8g CO2 Carry Case if you own a Byrna SD, EP, or HD launcher; pick the Loaded 12g version if you use a Byrna LE, TCR, or XL, or any launcher with a Boost Adapter installed.
Why the CO2 size matters
The main difference between these two carry cases is the CO2 cylinder size they are built for. The 8g case is designed for 8-gram cylinders, while the 12g case holds 12-gram cylinders. Your launcher determines which one you need, so the choice is straightforward once you know your model.
Both cases are semi-hard and use a sturdy industrial-strength zipper. They each hold six CO2 cylinders and three tubes of projectiles, so the carrying capacity is identical. The real trade-off is launcher compatibility, not capacity or build quality.
Compatibility is the deciding factor
The Loaded 12g CO2 Carry Case is compatible with the Byrna LE, TCR, and XL models, as well as any Byrna launcher with a Boost Adapter installed. The Loaded 8g CO2 Carry Case is only compatible with the Byrna SD, EP, and HD models.
If you are unsure which launcher you have, check the model markings on the frame or consult the manual. Choosing the wrong case means your CO2 cylinders won't fit properly, which defeats the purpose of a dedicated carry case.
Trade-offs at a glance
- Launcher compatibility: Check your launcher model first. The 8g case fits SD, EP, and HD; the 12g case fits LE, TCR, XL, and launchers with a Boost Adapter. Write down your launcher model before ordering.
- Capacity and build: Both cases hold six CO2 cylinders and three tubes of projectiles, and use a sturdy industrial-strength zipper. No difference in capacity or protection. If capacity is your only concern, either case works.
- Future-proofing: If you might upgrade to a launcher that uses 12g CO2, consider the 12g case now to avoid buying twice later. Think about your next launcher purchase before deciding.
