  • Active brake build on trigger contacts from SHS company
  • Easy installation inside the gearbox version 2; The wire length between the gearbox and the battery connector is 290mm
  • Completely made wiring allows the fastest and the easiest installation into the gun, it is long enough for all kind of weapons with battery placed in the stock; There are high quality power wires 1,5 qmm (AWG16) with thin and hard MPPE insulation and signal blue wire 0.34 qmm (AWG24) with MPPE insulation
  • Designed for spring up to M160 (equivalent for current 75A single shot fire or 25A burst fire for max. 30s). For higher load please use Active brake II (it is outside gearbox)
  • Board with electronics is coated with lacquer, it protects device against water
  • No current consumption in the idle mode; No sparking on switch contacts
  • Active braking uses the excess energy from the motor to stop it. The braking effect is the most powerful with high torgue motor
  • In auto fire mode piston stops in random position due the mechabox design
Professionally made mosfet with motor active braking designed for airsoft electric guns (AEG).
Device increases gun rate of fire and battery holds longer, than with basic wiring.
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).
It is fully integrated inside the gearbox version 2 instead of the original trigger contacts, compatible with Tokyo Marui standard.
Drop-in wiring with be battery in stock with DeanT connector - no soldering needed

"This has run flawlessly since I put it into my KWA SR-10, it's really snappy and smooth, the only thing I had to do was sand down a bit of the plastic so it fit smoothly.

"I bought this for my SR25. It works fantastically!

It is the best replacement for stock trigger contacts for the price. The active breaking is fantastic for a DMR, and I would definitely recommend. I trust Jefftron's products, and I believe that they rival GATE

~Easy to install
~No trigger contact arcing
~Great response, and ability to use 11.1v batteries with peace of mind

~Wiring is long and it may take some work to get the motor grip close
