Z-RAM Firing Bolt + Power-Pin stainless steel for Umarex HDR50 TR50 7,5 & 11 Jo. easy Install
Looking for serious performance without the frustration of tearing apart your marker? This Z-RAM Combo Set is the perfect solution for your Umarex HDR50 / TR50 – combining our high-performance Power-Pin with a precision-machined stainless steel bolt for a smart, hassle-free upgrade.
💥 Why this set?
Normally, removing the original power pin from the factory bolt is a nightmare – it’s made of soft aluminum and tends to get damaged during disassembly. With this kit, that problem’s gone: just screw the included Power-Pin directly into the new Z-RAM bolt and you’re done. No force, no damage, no stress.
✔️ Fits all Umarex HDR50 / TR50 7.5J & 11J versions (Gen1 + Gen2)
✔️ Bolt and pin made from durable stainless steel
✔️ Drop-in upgrade – no modding needed
✔️ Unlocks 20-30+ joules with compatible setups (e.g. longer barrel, EX25)
✔️ Works with EX25-Valve and standard HDR50 valves
🔧 Installation Tip
For best performance, we recommend removing the valve disk and chamber block inside the grip. Combine with Z-Extension and Tuning Barrels for maximum results.
