Full description


The NanoAAB MOSFET from Gate Electronics is a great way to squeeze a lot of extra performance and reliability out of your stock AEG for not a lot of money. With a little patience and a soldering iron you get everything you need in the box to give your rifle a new lease of life. The two main benefits of a installing the NanoAAB are:

  1. You prolong the life of your trigger contacts, as all the battery power is directed to the motor.
  2. The Active Braking system means that the motor will always stop turning after a full rotation of the gears (in semi-auto). This means that the piston will always stop in the forwards position, ensuring the main spring is always left de-compressed - further prolonging the life of your gearbox.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
