Powerkit.50 V2 – Performance Upgrade from 11 J to 20–30 J for Umarex T4E HDR / TR 50 GEN1 Revolver

Powerkit.50 V2: Maximum Output of 20-30 Joules for Umarex T4E HDR / TR 50 GEN1

The Powerkit.50 V2 is a precision upgrade designed to increase the muzzle energy of the Umarex T4E HDR / TR 50 first generation revolver from the original 11 J to a dynamic 20–30 Joules. This stainless steel kit improves performance through several key modifications:

• Optimized CO₂ Flow: The valve pin is equipped with a 2.5 mm hexagonal bore, which allows for much greater CO₂ expansion. The valve hole is also enlarged to 1 mm.
• Stability and Protection: The stainless steel material ensures better sliding and prolongs the life of the sealing ring.
• Longer Opening Time: A longer valve opening time releases a larger amount of gas, achieving higher output and reducing the "cooldown" effect.

It is recommended to store CO₂ cartridges at room temperature for optimal expansion and pressure. The installation is easy and reversible.

Technical Parameters

• Output: From 11 J to 20–30 J (more than 25 J, temperature dependent)

• Compatibility: Umarex T4E HDR / TR 50 GEN1 revolver (GEN1 only, not suitable for GEN2)
