A reader noticed this M16 magazine, being carried by a militiaman, in a video clip on Al Jazeera.
The magazine’s geometry is like none I can recall seeing. A couple of people suggested it could be a C-Products 7.62x39mm AR-15 magazine, but it is definitely not (see photo below).
Can anyone identify it? I think it is probably manufactured by the cottage gun industry in the Philippines.
