Nuovo gear box scarrellante da G&G

True to the faith of mimicking real firearms ,Top Tech is proud to present its new Pneumatic Blow Back system to its line of airsoft guns. Conventinal airsoft blowback utilizes tow hook springs to mimic real bolt actions, which often lead to excess wear and tear poor reliability in the gear box.
To alleviate the problem of conventional systems, Top Tech has independently developed the Pneumatic Blow Back system; a piston driven, gas operated mechanism to better mimic real life bolt actions. This new technique utilizes compressed air to move the bolt, which enables the action without adding extra stress to the gearbox. This class leading system represents a significant milestone in the airsoft industry.

1. Copper cylinder head used
The Top Tech gear box is using the advance version of copper cylinder head it's reduce the consequence of long term fricition of the traditional plastic cylinder head in causing with the change in air density level and decelerate the energy of gear turning.

2. Steel made of number 2 torque
Top Tech number 2 torque in gear box is using whole steel plate, Well finishing with CNC cutting machine. it's advance the density of hadness, enhance the durable of gear performance, and lower the chance from the demage.
3. high electric conduction of sliver electroplate wire set.
Whole series of TOP TECH Gear Box is using the high electric conduction of sliver electroplate wire set. highly efficiency of electrical conduct which decrese the wastage of energy in cell, effectivly using every unit of energy, in contrast, it;s extend the life time of cell, also meet purpose of green environment of word trend.
4. 8mm ball bearing used
8mm ball bearing is totally used in whole series, it's make the gear turning more stabilize and smoothly, bearing also strengthen
5.CNC AL6061 AEG Piston Head
CNC AC6061 AEG piston head used metal cylinder head to advance the hardness and more durable time, in compare with the plastic cylinder version.
6. MIM selector plate
MIM selector plate is totally used in whole series, it's enhance the durable.
