The ray guns on this page were created to portray retro-futuristic weapons from across the galaxy. They have the heft and feel of authentic decommissioned artifacts that were found on distant planets. None of them actually work mind you. That would be too dangerous (read: no active electronics). The ray guns are built out of mostly recycled and re purposed found objects. Most of them have functional spring loaded triggers to add to their authenticity. Some are even for sale.
Enjoy your look into the future's past.
