I don't know what they are called but it would have to be the insanely fast, automatic, "machine of mass destruction" that was featured in the movies Predator and Terminator 2.
It seems I saw a similar weapon on one of the various shooting shows but can't remember what they called it.
In Predator Jesse Venturas' character used it to mow down a large assortment of tropical foliage. In Terminator 2 Arnold used it to destroy a vast array of cars and other substantial objects(all without killing a soul. How touching!).

Rich,
I guess if we could afford one $20.00 a second wouldn't be a problem LOL!
Seriously though, This weapon has to be the most impressive firearm that I have ever seen.
The show I referred to above is American Shooter. They had a segment where a private individual had two of them mounted on a bipod. They fired them at night with tracer rounds which was a truly awe inspiring sight!
