Jefftron EXTREME PROCESSOR UNIT mosfet board for electric rifle

New professional programmable device with hi performance next generation circuit board
the new circuit will cut the current flow sent to the standard internal switch to a small signal current (switch have longer life)
then the electronic unit will encrease the peak and the current drain to the main motor for max performance 
then the board held the current drain directly bypassing the trigger switch
this give the stable current drain to the aeg without electricity drop by using max sp190 power spring
the most benefit are those long battery last and rate of fire enhancement
the unit is available and easy install on Marui m16, m4, mp5, g3, ak, aug, g36 aeg rifle and compatible
board size: 52x19x17mm
