Z-RAM Tec9 Custom Upgrade Package for HDR50 / TR50 (80 Jo. HPA)
📦 Shipping Notice:
Orders containing Tec9 Body Kits or related components will ship starting end of May.
If you include these items in your order, your entire shipment will be delayed until then.
⚠️ Note: This package does not include a marker or internal components!
You will need a Umarex HDR50 or TR50 as a base to complete the build.
This is the next-level Z-RAM Custom HPA Setup – designed for maximum performance and power.
Built around our Tec9-style body kit, this package includes a complete High Pressure Air configuration, delivering up to 80 Joules of energy.
Thanks to the modular barrel system and powerful air supply, this setup turns your HDR50 into a true less-lethal powerhouse.

Tec9 Build & Presentation
Included in this package:
✔️ Tec9 Style Body Kit (left + right shell)
✔️ 3-Drum Magazine Holder
✔️ 2x Barrel Cover – modular and stackable
✔️ ASA to Chamber Adapter (rear-mounted)
✔️ 1100 PSI Regulator with HPA Bottle
✔️ Tuning Barrel with Standard Extension
✔️ XXL Sniper Extension Barrel
✔️ Z-RAM Buttstock for secure shoulder support
✔️ Set of 6x Z.50v2 Steel Projectiles
✔️ All required small parts (screws, mag release, spring, grip insert, rear cap, etc.)
☝️ 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.
Safety instructions (even more important)!:
The possession and purchase of our spare part is permitted, the installation is prohibited in Germany due to the increase in performance and leads to the loss of warranty claims for your marker.
This is not an original Umarex part.
I would also like to point out the risk of injury that could result from using this power pin.
When using your marker in Germany, make sure that you do not exceed the legally permitted 7.5 joules. Liability of any kind is excluded. Use in Germany is not recommended! Sale only from 18 years!
We have many other interesting tuning parts and ammunition for your marker!
