Airsoft Systems ASCU Gen.5 Lite Smart Control Unit for Ver.2 Gearbox


The Airsoft Systems ASCU LITE is the "Take Down" version of their Gen.5 Smart Control Unit, with all the features of the Gen.5 but without programmable firing modes. ASCU LITE is designed with simplicity and functionality in mind. It is the easiest ASCU to be installed and used. It packs only the functions a player actually uses on the field. ASCU LITE is a hi-end single board electronic module, which, once installed in airsoft replicas, significantly improves their operation.


  • ASCU features a Low Drain Protection system specially designed to protect lithium-ion batteries (LiPo) from damage.
  • ASCU stops the replica's firing cycle in case of any problems, thus protecting the internal elements from further damage.
  • The sensor unit monitors the operation of the sector gear and thanks to that the whole system is capable of completing full cycles of the gearbox operation (a BB will never remain in the barrel when the magazine has been pulled and the spring will never be strained when the replica is idle).
  • ASCU unit is adapted for operation with new sensors that will prevent firing shots when the magazine is empty.
  • The unit expedites the reaction of the trigger in an AEG replica, which in comparison to the ordinary unit, is practically instantaneous.
  • It prevents accidental, double shots: when the trigger's consecutive squeeze is faster than a human reaction - each squeeze amounts to one shot.
  • Easy-to-install unit replaces connectors and an anti-reversal latch in any V2 gearbox, whose elimination completely reduces the jamming of the piston. Furthermore, it guarantees that a replica will complete a full cycle every time (the spring will remain in the loose state). ASCU controls the charge level of a battery and does not allow its over-discharge, which is very important when utilizing lithium batteries (LiPo, LiIon, LiFe).
  • The module detects issues and malfunctions by emitting a sound and vibrations as well as cutting off the power source, thus preventing further damage in a GB.
  • ASCU significantly prolongs battery lifetime.
  • It provides more possibilities than Systema Revolution or PTW at a significantly lower cost of installation and allows to make use of a wide array of spare parts available for standard V2 gearboxes.

  • Firing Modes:
    Safe + Semi + 3 Rds Burst + Full Auto
