The long awaited Revolution Gearbox by Systema is finally in stock, each set includes a Special MAGNUM Motor.
This package includes the Revolution Gearbox with a Systema M160 Spring for the M16A2 Series AEG. Designed for rear storage of batteries.
The Revolution is a drop-in fit for the Tokyo Marui M4/M16 series, and will fit most other brands as well, provided that they are made to a high enough standard and measurements close to Tokyo Marui. Compatibility with the V2 gearbox stops at the surface. The Systema Revolution gearbox mimics the V2 on the outside so it can be used with the common AEG, but an entirely different heart is beating on the inside. Note the extra beefy walls of this near gearbox, which is designed to withstand high powered springs for mind-blowing power levels unseen in traditional Marui-type guns.
An ingenious trigger unit called the E.C.U. is integrated into the Revolution. As the trend is with high performance electric guns, the design uses MOSFET components to allow a smooth flow of electrons from the battery to the motor, and eliminate arcing and high currents from the trigger unit. Instead of a mechanical cut-off lever, the E.C.U. has an optical sensor to detect the movement of the sector gear at all times.
First of all, the optical sensor allows the factory-programmed chip to make the gun shoot once on semi, and once only. Even a quick tap on the trigger activates the cycle, which doesn't leave the spring half-cocked like a traditional AEG does. This feature was exclusive for the PTW, but now it is available for AEG users as well.
Because the E.C.U. "knows" the position of the gears at all times, it will always stop the firing cycle in the same spot. Adding more current or active braking (by reversed polarity) when necessary, the E.C.U. keeps the shooting cycle consistent shot after shot. This allowed to omit another small mechanical part, namely the anti-reversal latch. Less moving parts translates to fewer mechanical problems!
The E.C.U. makes a proper three round burst possible as well, instead relying on complex mechanical parts or an inconsistent timer system as seen in older designs. As with real firearms, the burst stops as soon as the trigger is released, even if three rounds were not fired at that point. In fact, this circuitry can allow programming any number of rounds to be fired automatically on each trigger pull. So a 6 or 7 round burst is possible though it's not clear at this point whether Systema will make that user programmable.!
