Hughes Heligun

The Heligun was developed by Hughes Aircraft as part of a complete package for the OV-6 recon helicopter. It offered a number of significant advantages over the Minigun – it was half the weight, self-powered (not electrically driven), and had a mind-boggling 6000RPM firing rate. Ultimately, it was note adopted because the reliability (mean time between stoppages) couldn’t quite be brought up to par, and Army officials decided that it didn’t offer enough improvement over the already adopted M134 Minigun to be worth the switch.

    just looking for information on an .50 BMG rifle and machine gun that reduced recoil effect using a constant recoil principle I believe it was from Australia

    This beastie looks like a relative of the Gasst gun..1st ww german mg that was later developed by the soviets as an AA cannon.
    The gasst used twin barrels, the recoil of one used to load the other & eject the cases & achieved phenomal fire rates for ww1 standards. Anyone know if this is the same principle at work?
