Quick Answer
A fresh Byrna 88g CO2 cylinder delivers approximately 60 rounds—enough for three full 19-round magazines—at full velocity when used in the Byrna Mission-4 rifle.
Why the 88g Cylinder is Only for the Mission-4
The 88g CO2 cylinder is specifically designed for the Byrna Mission-4 rifle, not for handheld launchers like the Byrna SD or Byrna LE. Its larger size and higher capacity match the rifle's buttstock compartment, so using it in other models would not fit or function correctly.
Leak Risk After Puncture
Once the cylinder is punctured inside the Mission-4's CO2 buttstock, it will slowly leak over time even if you stop firing. This means you cannot partially use a cylinder and store it for later without losing gas. The best practice is to finish the cylinder in one session or swap it out knowing you will lose the remaining CO2.
Frequently Asked Questions
How many shots from one Byrna 88g CO2 cylinder?
A new, un-punctured 88g CO2 cylinder provides about 60 shots at full velocity—enough for three 19-round magazines from the Mission-4 rifle.
Can I use an 88g cylinder in a Byrna SD or LE launcher?
No. The 88g CO2 cylinder is only compatible with the Byrna Mission-4 rifle. Handheld launchers use smaller 12g or 10g CO2 cartridges.
Does a punctured 88g cylinder leak if I don't use it all?
Yes. Once punctured inside the Mission-4 buttstock, the cylinder will slowly leak CO2 over time. It is best to use the entire cylinder in one session or swap it out knowing you will lose the remaining gas. Always store spare un-punctured cylinders and avoid leaving a punctured cylinder in the rifle for extended periods.
