Ukrainian six-barrel recoilless shotgun system for mounting on an FPV is called “Predator Shooter”, developed by the Ukrainian company 3D Tech.

This system uses 12 gauge shells, apparently with a second shell firing backwards as the recoil compensation.

There is also a two barrel system to allow higher FPV speeds.

The FPV has a thermal camera, as one of the intended targets of this system is Russian drones that dangle lines to entangle the propellors of Ukrainian heavy drones at night.
