It's recoilless with two cartridges firing in opposite directions.

It can also work autonomously from 126m.

Very cunning this Ukranian tech.

From the pictures the shot gun appears to be more of a "zip gun" - a home made/improvised gun. The barrel is a tube while the shells seem to have some kind of squib or electric match replacing the shells percussion cap. That removes the weight of a mechanical gun mechanism with firing pin. This feels like a case for moving towards electronic firing case-less ammo perhaps?

Not to rain on the parade...but this is innovation with a very small "i". Aircraft using guns against each other was SOP in WWI, and they were already using recoilless (in the air) back then.
