I'm pretty sure this is an auto tracking and firing mag, I could be wrong and it's a +P salad shooter.

The company that makes them (meggitts) looks like it may still be in business, they were building live fire firing ranges. I was able to find another pic of a different unit that makes me skeptical of the first one I posted.

I think this one is a complete unit and will probably work as intended, the one in my first link not so much.
