Real or Mockup?

I saw this rifle in a film clip many years ago. And it's been driving me bonkers trying to think of what it could be. Is it a real firearm or is it just something knocked together for the camera? At this point I would be happy with some clues to fall down a rabbit warren with, but nothing turns up on google.
