This is a Fan made reproduction of the custom weapon from the game Fallout 3, the Railway Rifle. It is a prototype made from reference photos and drawings.
The non-working replica is made from metal tubing, PVC, and wood (held together with metal screws, foam, and glue). It was painted to resemble the model found in game.
I built this with the intention of taking it to a Sci-Fi convention, but now I need to pay the rent. The rifle would be a great costume or show piece, making your Fallout 3 costume complete.
