This pic was sent over to me by SSD’s Admin, so I don’t know the origin. What I can say is, based on it being a pic of “Batou’s Shotgun”, it’s obviously a prop from the upcoming (and quite honestly craptastic-looking) Ghost in the Shell movie. It also happens to be a duded up Crye Precision Six12 rotary drum bullpup 12 gauge shotgun, which to be fair is a pretty futuristic-looking piece.
Edit: Google image search came up with this page: beagle-voyage.com/movie-ghost-in-the-shell-movie-props-2016.
There’s a few other prop weapons from the movie as well.
