  • Active braking MOSFET
  • Wiring included
  • Compatible with Microswitch V2 gearboxes

If you're running an AEG equipped with a microswitch V2 gearbox and need a faster trigger, the Cybergun JeffTron Switch Brake MOSFET with Wiring is what you need! This Active Braking MOSFET is designed to replace the original microswitch trigger system and comes pre-wired with high-quality AWG16 and AWG24 wiring. As with any internal upgrade, we suggest consulting a tech before attempting installation if this is your first time!

This MOSFET is designed to prevent the piston from stopping in a random position when you take your finger off the trigger when shooting full auto and ensures only a single cycle is completed in semi-auto. Rate of fire and trigger response should also improve thanks to electrical efficiency advantages when compared to standard microswitches. This MOSFET is only designed for microswitch trigger-equipped V2 gearboxes and isn't likely to work with standard V2 or other gearbox types.

The QSC Gearbox shell also features radiused cylinder window corners to better distribute force and is pre-cut for Gate TITAN/ASTER, Perun Hybrid or Delta Armory ETU MOSFET systems, meaning no need to get the Dremel out to add advanced functionality. The bearing ports are 8mm in diameter, making this the perfect host for Bolster Armouries EZO Ball Bearing Bushings. If you're reaching for the stars when it comes to performance and want your build to last more than a few bursts, the Delta Armory Version 2 CNC 8mm QSC Gearbox Shell is what you need!

  • For Gate TITAN II equipped AEGs

The Magazine sensor is programmable through the TITAN II itself and Gate Control Station App, allowing you to set the round count of your magazine so it cuts off when you run out of rounds. The sensor will also prevent firing when a magazine is not inserted, but this function can be turned on and off via the GCS app.
