Power Kit Umarex T4E HDB/TB 68 7,5J - 50J+

With this kit, you can increase the muzzle energy of the Umarex T4E HDB/TB 68 RAM gun (only  7,5J version) to more than 50 Joules (depending on the ammunition used). With higher energy, the number of shots per one CO2 cartridge decreases.

PRINCIPLE OF OPERATION

The Power Kit contains 2 main components that need to replace the original parts in the gun: the Restrictor (a round plate) and the valve pin (a threaded cylinder). Thanks to the use of stainless steel, they ensure better smoothness and protection of the sealing rings and at the same time better withstand the cooling effect of the flowing CO2 gas.

• The restrictor with a larger opening allows faster CO2 gas flow from the cartridge into the valve.
• The modified valve pin ensures longer valve opening, so in combination with the tuning restrictor, you achieve higher muzzle energy at the cost of higher air consumption.

INSTALLATION PROCEDURE

• Installing the restrictor is simple - you first need to remove the original restrictor located inside the chamber for the CO2 cartridge and replace it with the new one using the supplied screw.
• Installing the valve pin requires complete disassembly of the weapon, where it is necessary (preferably with a heat gun) to heat the valve (the blackened cylindrical part), into which the original valve pin is screwed (it is necessary to soften the thread adhesive). Then install the new valve pin using the included Allen key and reassemble the weapon.
• At the same time, we recommend checking for the presence of the valve block, which is often found in lower powered models. It is the metal part above the restrictor that can be hammered out backwards during weapon disassembly after unscrewing the brass plate with the activation indicator.

WARNING: This modification voids the weapon’s warranty!
