Modify PIN EXTREM KIT for GEN.2 – Unlock the Full Potential of the New Generation

The Modify PIN EXTREM KIT represents the ultimate upgrade designed directly for owners of Umarex HDR 50, HDP 50, HDR 68, and HDB 68 guns in the GEN.2 version. This stainless steel kit was developed to eliminate the primary limitations in the gas distribution system of modernized models and allow them to reach their true maximum muzzle energy.

Important notice for GEN.2 modification: Simply replacing the PIN is a fundamental but only the first step of the entire modification for generation 2 versions. Although the new PIN ensures significantly higher CO2 flow, a plastic restrictor (flow limiter) is still present inside the valve chamber (silver block) from the factory in GEN.2 models. If this limiter remains in place, the gas still hits the original barrier, and the new PIN cannot fully utilize its potential. To achieve truly maximum performance, it is necessary to disassemble the gun, reach the valve, and remove this plastic element. Only after its removal will the system fully open, and the power increase will be immediately noticeable.

This kit is intended for experienced users and tuners who demand the maximum from their GEN.2 gun. Thanks to precise stainless steel craftsmanship, you get a component that is ready for extreme loads and significantly increases the reliability of the entire release mechanism.

Technical Parameters and Specifications:

• Material: High-quality Stainless Steel
• Compatibility: Exclusively for Umarex T4E GEN.2 models (HDR 50, HDR 50-L, HDP 50, HDR 68, HDB 68)
• Design: Enlarged internal channel for maximum CO2 flow
• Purpose: Maximum increase in muzzle energy and projectile velocity for second-generation models

Tips for Correct Operation:

• Cap Tightening: The CO2 cartridge cap must be tightened all the way to prevent micro gas leaks.
• Activation (Emergency Push): When activating the piercing mechanism, strike the bottom more firmly than with a standard PIN to ensure certain cartridge piercing.
• CO2 Quality: Use only high-quality and full CO2 cartridges to ensure constant pressure.

Frequently Asked Questions (FAQ):

1. I installed the PIN into my GEN.2, but the performance didn't change. Why?
For GEN.2 models, this is caused by leaving the plastic restrictor inside the valve chamber. As long as this limiter is in place, the gas cannot flow faster even with a higher-flow PIN. Removing the restrictor is essential for maximum results.

2. Is the installation safe for my GEN.2 gun?
Yes, the kit is made of stainless steel, which is mechanically more durable than the original part. However, please note that higher performance increases the stress on internal components and leads to higher gas consumption.

3. Is it necessary to adjust anything every time I change a cartridge?
No, once the PIN is correctly installed and the internal restrictor is removed, the system works permanently and requires no further intervention.
