A friend of mine has a 100 ? round drum magazine made by Firepower Inc of Hancock, Maine. Neither one of us knows anything about these mags. Not much on the web about them at all. Would like to know how to load and repair them. We don't even know if this thing works. Any info would be great.
It is a round metal drum with a clear plastic cover on one side. Out of the top center is what looks like a 5 round regular Ar mag.
