Z-RAM Firing Bolt + Powerkit.50 V2 for HDR50 TR50, export valve for Gen2+Gen1  11J Version (20-30Joule+)

 

Includes Powerkit.50 V2 + Z-RAM Stainless Steel Bolt
Output: 20–30+ Joules

Want to turn your 11-joule Umarex HDR50 / TR50 into an absolute beast? This combo is the cleanest and strongest way to do it. Our Powerkit.50 V2 boosts your revolver to 30+ joules* of raw performance – and the included Z-RAM stainless steel bolt solves the #1 frustration: removing the fragile factory Power-Pin. Just screw the new one into this heavy-duty bolt and skip the struggle.

💡 Why this set is smarter:
The original bolt from Umarex has a press-fitted aluminum pin that often breaks during removal. This kit saves you time, stress, and broken parts — just install the new Power-Pin directly into our steel bolt and you're done.
