This model cannot fire, nor can it be modified to do so. This model is my interpretation of Lucy's tranquillizer gun she is seen using at several points in the first season of the Fallout TV show.
This model features a sliding "chamber" for accuracy's sake and has a printable dart that can be inserted into the model or used as a prop for a bandolier.
This is split into several parts for simple printing and requires no dowels or rods for stability.
