I actually mounted a short 4X scope to the slide of a top-eject Winchester 94 once. When the lever was cycled the empty brass would eject in front of the scope. It would consistently shoot 2" groups at 100 yards and the neighbor I did the job for who couldn't use the iron sights any more due to failing vision and didn't like offset scope mounts kept harvesting deer with it for several more years. Some bubba jobs might offend the purists, but they still get the job done.
The gun in the video is just too fugged-up for words, however!
