Mattel Tommy Burst Machine Cap Gun. It is made of Metal and Plastic.
This toy gun will work by pulling the trigger, but Not Working when you pull the bolt back. The rear site and cap cover are missing. I have a piece of plastic where the cap cover would be so the cap gun can fire caps. The gun uses perforated roll caps that are available on this web site. The gun is 25″ long and has overall play wear.
