Z-RAM Upgrade Package for Umarex HDR50 TR50 (40 Jo. 12g CO2)
This high-power upgrade set takes your Umarex HDR50 / TR50 to the next level – hitting up to 40 Joules with standard 12g CO₂. Designed for performance and precision, this build combines dual Z-Extensions, a modular barrel system, and our powerful Z.50v2 steel projectiles.
The extended barrel and compensator setup boost range and consistency, while the included angled foregrip adds both stability and style. Ideal for tactical users looking for a serious power upgrade without switching to HPA.
Included in this package:
✔️ 2x Z-Extension – maximizes chamber volume for serious power
✔️ Tuning Barrel with Standard Extension – optimized for .50 cal performance
✔️ Sniper Barrel Extension – adds range and velocity
✔️ Barrel Cover – for a clean finish and added barrel protection
✔️ Universal Angled Foregrip – better control & ergonomic handling
✔️ Set of 6x Z.50v2 Steel Projectiles – hard-hitting, reusable stainless steel ammo
⚠️ Marker not included.
Performance:
⚡ Approx. 40 Joules with 12g CO₂
🔄 4–6 powerful shots per capsule
📦 Optional Modify Pin (sold separately) for ~10 shots at ~34 Joules
🚧 Important Note:
This setup requires cutting the back of your stock HDR50 housing to allow both Z-Extensions to fit. If you want a plug & play solution with clean fitment, we recommend using one of our body kits (e.g.ZDR50, ZDR50v2, Tec9 Style).
💡 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.
