Dillon's DAC3000 Clutch Assembly is integral to the operation of the Dillon Feeder/Delinker. Its function is to control the engagement/disengagement of the delinker in time with the gun.
The DAC3000 also ensures the weapon is clear of live ammunition each time the trigger is released. When the gun trigger is pressed, power is delivered to the gun and to the clutch. The clutch then engages the delinker drive gear, causing the delinker to feed ammunition to the gun. When the trigger is released, power is first removed from the clutch, which disengages the delinker, stopping the flow of ammunition. A time delay relay continues to turn the gun barrels until the six remaining rounds are fired. In this way the M134D is always free of live ammunition. Also, since there is no live ammunition in the chambers after firing, the M134D is not susceptible to accidental discharges resulting from "cook-offs".
