💡 Note: For best performance, we recommend adding a suitable Power Kit that matches your specific marker model.

☝️ This setup is fully compatible with the Z-RAM EX25 valve. It eliminates the need for a separate Z-extension—unless you want a dual-Z-extension configuration. Another advantage: The EX25 valve allows the use of 16g, 20g, or 25g CO₂ threaded capsules for compact configurations.

⚠️ Important: Requires a functioning Umarex HDR50 or TR50. This package includes external upgrade components only.
