A device for tracer stream simulation is disclosed. The device includes a casing having an aperture, a beam splitter, and structure for generating a first image. The aperture is capable of displaying first and second fields of sight. The beam splitter conveys a second image to the first and second fields of sight while superposing the first and second images in the first field of sight. A system for tracer stream simulation is also disclosed and includes a biocular sight with the device being adapted for attachment to the biocular sight. A method for tracer stream simulation in a biocular sight is also disclosed.
