Product Description

This is the BIGRRR  processor controlled mosfet. This Mosfet is a great drop-in-mosfet which allows you to change shooting modes, controls RoF, pre-cocking, active braking, low battery indication, statistics etc. 

Device is fully integrated inside the gearbox version 2 instead of the original trigger contacts. Comes with completely made wires to stock and to magazine terminals with mini fuse and XT30 connector — no soldering required, unless you want to change connections.

The BIGRRR has a built in temperature sensor and adjustable electronic fuse to prevent damage from overloading. As a further failsafe to protect the device and battery from short circuit a micro blade fuse is fitted in the battery wires.

  1. Significant improvements of ROF and ability to pull larger springs with less heat created over standard equipment.'
  2. Increase the life of LiPo batteries and protect them from damage and from blowing up.
  3. Built in failsafe: theBIGRRR comes with a mini-blade fuse and an electronic fuse to protect your investment from damage due to overloading.

Whilst optical sensors that are used on other brands of FCU (Fire Control Unit) might be suitable for AirSoft they are limited in Gel Blasters why? Gel Blasters are frequently used in Full Auto because the ammunition is cheap and environmentally friendly, also because it's fun and to hit anything you need to shoot a lot more gels!

Constant and rapid cycling of the Mechbox creates excessive heat and wear on internal components without adequate lubrication. Optical sensors fail to operate when obscured by lubricants, subsequently using such devices means you cannot adequately lubricate a mechbox with an FCU that uses optical sensors. The BIGRRR uses mechanical switches that operate flawlessly when covered in lube. We have Blasters that have worn out gear sets, motors, pistons and about every other moving part but the BIGRRR keeps on operating flawlessly.


Motors that have not been adequately insulated at the factory can cause a short circuit which will damage the BIGRRR during operation. We strongly recommend that ALL motors new or old are thoroughly tested prior to installation to avoid causing damage that is NOT COVERED by warranty. At the very least remove the brush contacts from the motor and ensure there is no continuity between the two brush plates.
