Field Tips
- When inserting a new 12g CO2 cartridge, tighten the base screw in a swift, continuous motion until you hear a brief hiss stop, securing a tight seal without over-crushing the piercer pin.
- Use a standard push-style speedloader to fill the double-stack BB channel quickly from the top feed lips or lower loading cutout.
- Always unscrew and remove depleted CO2 cartridges when storing the magazine long-term to prevent permanent compression of the internal puncture O-ring.
- Apply a drop of pure silicone oil directly to the tip of every 3rd or 4th CO2 cartridge prior to insertion to keep internal seals conditioned and leak-free.
