"[People Magazine] asked people to recreate scenes from famous movies in a photo. They asked Andy Samberg and I if we wanted to recreate a scene from a movie like Butch Cassidy and the Sundance Kid, and we said that sounds great, but we’d rather do a scene from E.T. You might be like, “How could you and Andy do that; one of those is a child and one of those is an alien! Well, I feel like we nailed it.” - Seth Meyers
That’s hard to answer, but when asked questions like this I tend to think of the many lever action and bolt action designs that the US Army rejected in favor of the single shot breechloading Springfield Trapdoor. The one that really comes to mind is the Lee Remington, a bolt action rifle by James Paris Lee with a ten round detachable box magazine. Lee presented it to the Army in 1882 for trials. The US Army only ordered limited numbers as did the US Navy> Afterwards Lee would take his design to Britain, where it would become the popular Lee Enfield rifle.
There were many others too that the Army rejected like the Winchester Hotchkiss (1878)
Remington Keene (1878)
and the Springfield Chaffee-Reese (1882)
