GE GAU-6 Minigun
The GE GAU-6 Minigun was designed for helicopters & light aircraft & fires 5.56mm rounds at variable rates of fire from 1,000 to 10,000 rpm. The gun and drive weigh 15kg and the driven variant uses 0.75 -> 3.2 hp dependent on the rate of fire. The gun can be powered by NiCad batteries (don't know the weight, sorry) with a duration of 80,000 rounds at 1,000 rpm. Unfortunately the recoil force is 110kg at 10,000 rpm which would knock you off your feet, but (assuming a linear relationship) if the rof were 1,000 rpm then the recoil should be only 11kg.
