For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
Yesterday I was wandering aimlessly and look what I found. It was used in a movie from 2002 called 'Showtime'. It appears to be some sort of custom SAIGA-12 =) It may not be a 40k bolter, but it is pretty damn close.
