Xcortech X3300W Advanced BB Control System is a 3 piece set that comes in either Black or Tan. It comes with a PEQ command box, a BB tracer unit and a Burst ECU Mosfet system.
It's strange to think that these 3 items will work in tandem with each other, but they actually do. Once doesn't really need the ECU system, but it can be very useful. It's a MOSFET that allows you to burst fire (only when the fire selector is on full auto) from 2 – 10 BBs per trigger pull and hold. It works with the command box so you can set it how you like.
The silencer works in tandem with the command box and also acts as a tracer / chrono. It also lets you know the rate of fire of your AEG or GBBR. It fits on a 14mm CCW thread as the box itself can be placed on any 20mm rail mount. The top is preferred as it is easier to read.
