they look like a neat idea. don't know how reliable they are.

I researched them on the web a while back. They seem to be reliable, but the cost of the drums and the magazines is quite considerable. 90 dollars for a 10 round drum, and 45 dollars for a 6 round magazine. I wouldnt mind one for a range fun gun, but at those prices Id be more likely to keep my pump, or look at the saigas.
