Z-RAM Firing Bolt + Powerkit.50 for Umarex TP50 HDP50 13J Version | GEN.2 | Exportventil | 20-30J+
Includes Powerkit.50 + Z-RAM Stainless Steel Bolt
Output: 20-30+ Joules
Ready to push your Umarex TP50 / HDP50 13J (GEN.2) to the next level? This combo set is made for serious users who want a clean install without the headache. The Z-RAM stainless steel bolt comes prepped to receive the included Power-Pin — no need to destroy your original aluminum pin during removal. Just screw it in, lock it down, and you're done.
💡 Why this combo makes sense:
The factory pin is often pressed in and tends to get damaged during removal. Our solution: skip the frustration and start fresh. You save time, effort, and nerves — and gain power.
