Z-RAM Firing Bolt + Powerkit.50 V2 for Umarex HDP50 TP50, export valve, Gen2 + Gen1 , 7.5j version 20-30J
Includes Powerkit.50 V2 + Z-RAM Stainless Steel Bolt
Output: up to 30 Joules
Take your Umarex HDP50 / TP50 to the next level with this high-performance combo! The Powerkit.50 V2 delivers massive output (20–30J), and the included Z-RAM Stainless Steel Bolt lets you skip the nightmare of removing the factory aluminum pin — which often breaks or gets damaged. Just screw the new pin into the steel bolt, drop everything in, and go. Easy install. Big results.
💡 Why this combo saves you stress:
Removing the original Power-Pin from the factory bolt is a major pain — it’s press-fitted, fragile, and frustrating. This kit solves that by giving you a ready-to-install steel bolt. Time saved. Nerves spared.
