Overview

The Byrna Mission 4 is engineered around larger CO2 cylinders to provide the air volume needed for its higher performance capabilities. Compared to compact launchers that utilize smaller CO2 cylinders, the Mission 4 uses high-capacity cylinders to help maintain consistent velocity, extended range, and increased shot capacity.

The launcher accepts both 88-gram and 90-gram threaded CO2 cylinders. These cylinders thread directly into the rear of the launcher, creating a secure seal that allows the system to regulate and deliver CO2 efficiently during operation.

Byrna offers 88-gram threaded CO2 cylinders for Mission 4 users. While 90-gram cylinders are also compatible, they must be purchased from third-party manufacturers. Users should note that performance can vary among aftermarket brands, and Byrna does not recommend the use of Crosman CO2 cylinders with the Mission 4 platform.

How It Works

1. Select a compatible 88-gram or 90-gram threaded CO2 cylinder.
2. Thread the cylinder into the rear of the Mission 4.
3. Ensure the cylinder is properly seated and sealed.
4. Operate the launcher using CO2 propulsion.
5. Replace the cylinder when it becomes empty.
