Z-RAM Tec9 Body Kit for Umarex HDR50 / TR50 inerts (hides z-extension)
📦 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.
Transform your Umarex HDR50 or TR50 with this tactical-style Z-RAM body kit, inspired by the compact Tec9 design.
Made from durable material with an ultra-smooth surface finish, the layer lines are barely visible – a major leap in 3D print quality.
The housing is fully compatible with both the original Umarex valve and the powerful EX25-Valve by Z-RAM.
Whether you're using a Z-Extension or the EX25-Valve, this body hides everything cleanly inside – no cutting required.
Plus, a rear port is already integrated, allowing for easy installation of an ASA to Chamber Adapter.

Included in this kit:
✔️ Left & right body shells (ready to assemble)
✔️ Matching screws
✔️ Removable grip piece (for easy CO₂ access)
✔️ Extended trigger for drum release
✔️ Spring-loaded release button
✔️ Optional rear cap to close the ASA port
⚠️ Note: This kit requires a Umarex HDR50 or TR50 marker as a base.
To complete your setup, we recommend the matching magazine holders (available in 2- or 3-drum versions) and our Barrel Cover – ideal for longer tuning barrels with extensions.
Whether used on its own or as part of a full custom build, this body kit is the perfect foundation for your high-performance HDR50 tuning project.
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!
