Z-RAM Upgrade Package for Umarex HDR50 TR50 (35 Jo. 12g CO2)
Looking for a clean and effective upgrade path for your Umarex HDR50 / TR50? This custom package includes everything you need to push your marker to 35 Joules using a standard 12g CO₂ cartridge – including power-boosting internals and a tactical grip for better control.
The included Z-Extension, tuning barrel, and barrel cover work together to deliver consistent performance, while the angled foregrip improves handling and adds a tactical look. A set of Z.50v2 steel projectiles rounds off the package, so you're ready to go.
Included in this package:
✔️ Z-Extension – boosts power by increasing chamber volume
✔️ Tuning Barrel with Standard Extension – optimized for .50 cal accuracy & range
✔️ Barrel Cover – clean look, protects the barrel
✔️ Universal Angled Foregrip – for improved handling and stability
✔️ Set of 6x Z.50v2 Steel Projectiles – high-impact stainless steel ammo
⚠️ Marker not included.
Performance:
⚡ Approx. 35 Joules with 12g CO₂
🔄 About 6 high-power shots per capsule
📦 Optional: Use with a modify pin (sold separately) for ~10 shots at ~30J
🚧 Important Note:
This setup uses the stock HDR50 body. In order to fit the Z-Extension, you will need to cut an opening in the rear of your marker housing. Without a compatible Z-RAM body kit (e.g. ZDR50, ZDR50v2, Tec9), the extension won't fit flush. This modification is purely external but requires precision and care.
💡 Note: For best performance, we recommend adding a suitable Power Kit that matches your specific marker model.
This is not included in the package, as there are different versions for each model.
The Power Kit provides additional power and ensures better sealing under increased pressure and gas flow – a perfect addition to your upgrade components.
