🔥 Why Z-RAM?

Z-RAM builds tactical RAM upgrades that hit hard and look good. The ZDR50v2 Set was our first all-in-one EX25-ready kit – still a clean, compact alternative to the Tec9 housing.

It’s lightweight, simple to install, and fully modular with all other Z-RAM parts like tuning barrels, barrel covers and mag holders.

➡️ Upgrade now – and give your HDR50 / TR50 the tactical edge it deserves.

📌 HDR50 marker not included – this set contains external upgrade components only.

💡 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.
