Without having to fight the compatibility of internal parts, assembly and shimming.  Customer has to insert gearbox into body.

Table of parameters:

 Gearbox Reinforced gearbox with quick spring dismantling (QD). Reinforcement is mainly in area above the cylinder head. Gearbox is much wider on this place and it reduces the risk of breaking. Gearbox can hold M130 spring without and issue (according factory).

Some tips for installation:

  • If you want to install M130 spring, please remove piston head bearing. Spring wont fit. Or cut about 1cm of the spring.
  • We do not recommend lipo battery 11.1V due to high currents, which can cause contact tan.
  • Spring in the gearbox can be changed only before inserting into the body of weapons. After that, this is not technically possible, because the rear part of the body usually has not hole for spring remove.
  • We have tested this gearbox on Dboys and AimTop brand only. For other models, we can not confirm compatibility. Technically it is possible to install gearbox to other brands, but may require minor modification. Ensure good alignment with the chamber and barrel.
  • Gearbox is designed for M4 / M16 / SR16 / HK416, etc. Due to the length of the nozzle, trigger and selector plate is not possible to install gearbox into MP5 or SCAR.
  • Make sure HopUp chamber fits well on the gearbox. For example DBOYS must narrow the diameter of the fitting, which is inserted into the gearbox.
  • After a test installation of the gearbox into DBOYS AEG we got velocity 130 m/s.
  • The warranty period is two years. But replacing of the spring is very easy and we can keep an eye on the customer exchange to extremely strong spring. It can shorten the life of the internal parts or completely damaged the gerabox. For this reason, the warranty is on the product mistakes only. Not on the common wear (for example, worngears, trigger contacts the piston .. etc.)
