Professionally made program-controlled device with motor active braking, designed for airsoft electric guns (AEG).

It adds new ways of shooting, controls rate of fire, pre-cocking, active braking and low battery indication.

Designed for all airsoft electric guns (AEG). Limited functions for guns without semi fire capability (M249, M60, etc.). 


Main parameters:

- Presoldered wires allows faster and easier installation into the gun, it is long enough for all kind of weapons

- Five new shooting modes - combination semi, burst and auto fire

- Adjustable burst (from factory are 3 shots, it can be changed in the range 1 - 10 shots)

- Smooth change rate of fire using PWM motor control

- Pre-cocking function for instant shot in SEMI fire

- Quick first shot at reduced rate of fire

- Mosfet with motor active braking

- Adjustable strength of active braking (can be also disabled)

- Low battery indication 2S Li-pol, 3S Li-pol, 3S li-fe, 3S li-on, 4S li-pol and 4S li-fe

- Coated with lacquer, it protects device against water

- Monitoring current, voltage and temperature of Processor unit components

- Trigger gun is used for programming this device, motor vibrates as a feedback for user

- Programmed settings are stored in processor unit memory, so it doesn't loose changes after disconnection the battery 


Fire modes:

- Safe - Semi – Auto (unchanged gun function)

- Safe - Semi - Semi/Burst/Auto 

- Safe - Semi - Semi

- Safe - Semi - Semi/Burst

- Safe - Semi - Semi (delay between shots, motor vibration when it is ready to fire)

- Safe - Burst - Burst/Auto



- Versions with universal wiring, which are long enough for all kind of weapons. Simply cut wires to the required length and attach connectors

- Four high quality 1,5qmm (AWG16) power wires covered with silicon insulation and two 0,25qmm (AWG24) signal wires

- Designed for spring max. M190

- Mosfet handles up to 2.5 times bigger currents than it's cheaper variant

- 5 times better switch on resistance = lower mosfet heating

- Cooler for heat dissipation, it is glued to mosfet

- Braking mosfet handles up to 2.3 times bigger currents than it's basic variant

- Device size 52x19x17mm

- Easy to understand 6 wires connection

- For right function is necessary to have a functional gearbox cut off lever, selector plate, reverse latch, trigger and trigger block, as it has the standard gearbox

- Specified for common batteries up to 17 V (Ni-xx 8.4V - 14,4V, li-pol 7.4V - 14.8V, li-fe 9.9V - 13.2V)

- Current device consumption only 4.5 mA in idle state

- Device increases gun rate of fire and battery holds longer, than with basic wiring

- With active braking 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) 

- In weapons with very high rate of fire (ROF) active break solves multiple shots in semi mode

- The braking effect is the most powerful with high torque motor

- In auto fire mode piston stops in random position due the mechabox design. But it stops much faster with active brake
