  • Coated with lacquer, it protects device against water
  • Disable active braking by unplugging red jumper, when you gun has Rate of fire under 20bb/s, otherwise it could lock up trigger on SEMI due too low gear speed
  • Motor will be under less stress without active braking
  • Designed for spring up to M160 (equivalent for current 75A single shot fire or 25A burst fire for max. 30s)
  • Active braking uses the excess energy from the motor to stop it. The braking effect is the most powerful with high torgue motor
  • No current consumption in the idle mode; In auto fire mode piston stops in random position due the mechbox design
Professionally made mosfet with active braking, which can be disabled by removing red jumper. Device is designed to replace microswitch in the specific gearbox V2. There is no modification needed.
In semi fire mode piston isn't partially stretched, spring is fully released, parts in mechabox aren't under strain and nozzle locks hop-up chamber in greater part (depends on ROF).
Active break solves multiple shots in semi mode with weapons with very high rate of fire (ROF).
Device increases gun rate of fire and battery holds longer, than with basic wiring.
