Fully tuned gorilla fcu by KA Tech Airsoft 


An FCU (Fire Control Unit) is needed for all Polarstar rifles with the acception of the Polarstar Kythera whether it’s the standard Polarstar FCU or a Gorilla FCU. The Gorilla FCU gives you the ability to change the setting of your HPA rifle on the fly via a mobile app and blue tooth. The app offers unlimited presets for any rifle so you can plug this into a CQB rifle and load one tune, then plug it into a DMR and load a different tune. If buying this with a Polarstar rifle from the airsoftUS it will come pre tuned for that specific rifle. If your buying this as a solo product and you would like it tuned for your rifle please fill out the contact form or leave a comment giving the following details, the more specific the better 

  • Which Polarstar Engine - Ex. Polarstar Jack
  • Hopup unit ------------- Ex. Maxx me pro M4A
  • Bucking ---------------- Ex. Maple leaf macron 70 degree
  • Inner barrel ------------- Ex. Prometheus 6.03 363mm
