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.
Top Tech gearbox uses CNC processed copper cylinder head. It reduces the change in air density which decreases the energy that is often caused by the wear and tear occurs with the traditional cylinder heads after a long period of use.
2. Steel Spur Gear
The spur gear in Top Tech gearbox is manufactured by cutting from steel sheet using CNC machines. The durability and hardness are enhanced and the potential damages from operations are minimized!
3. High electric conduction silver-plated wire set
Top Tech gearbox uses the silver-plated wire sets which are highly efficient in electric conduction that minimizes the chances of the batteries from running down and maximizes the battery's effectiveness and durability, which also achieves the aspect of environmental protection.
4. 8mm ball bearing
Top Tech uses 8mm ball bearing in its entire range of products to stabilize the gears' rotations and enhances the strength in bearing.
5.CNC AL6061 Piston Head
Top Tech uses the CNC AL6061 AEG aluminum piston head. The aluminum piston head increases the durability and strength compared to the ordinary plastic versions.
6. Steel selector plate
MIM steel selector plate is used in the entire range of Top Tech products which increases the durability than the ordinary selector plates.
