An upcoming product from Xcortech is getting a close attention from us. Called the Xcortech Airsoft X3300W Advance BB Control System, it's a system that allows you to do the following: determine ROF, Muzzle Velocity, Count Down, Count Up, Tracer fire, Burst Control, etc. This system is comprised of a tracer unit, a MOSFET, and the control unit which is shaped into a PEQ box to mount on rails. No details yet on when this is going to be released though but it's definitely this year.
