The video above is a scene from MINORITY REPORT, the 2002 sci-fi film starring Tom Cruise that was based on a short story by Philip K. Dick.
In the scene you get to see an awesome weapon in action. I’ve seen it referred to as a Pre-Crime Shotgun, a Concussion Rifle, and a combination of both of these.
Having not read the short story (yet), I’ll go with Pre-Crime Concussion Shotgun for now.
There’s no official movie prop replica available of this weapon that I know of, unfortunately. But if you know of one, by all means let me know in the comments below! Yeah I know, that’s a lot of know’s…
