🔥 Why this kit?

Before we launched our EX25 valves and Tec9 builds, this was the cleanest way to get real power with your stock HDR50. Still a top pick if you want full performance with the factory valve – and zero compromises in looks or function.

➡️ Tactical. Efficient. No ugly mods.

💡 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.
