Regular price $194.00


Breaking the way traditional gunsmiths adjust the gear gap so that the entry player can easily complete.


  • Steel gears are hardened and durable
  • Modular design, no need to adjust gear clearance
  • Easy to install and easy to maintain
  • Recalculate the size of the upper cam and shorten the stroke of the lever
  • With a safety check valve, the “one” groove on the Anti-Reversal Latch is designed to quickly and safely release the electric gun spring before opening the gearbox.



High-speed gear (lower ratio) increases ROF of AEG. The standard ratio has the same ratio as stock AEG. High torque gear has a ratio higher than stock to operate stronger spring to achieve higher muzzle velocity.
