Let me know if you find a source for a FAL drum mag. I've got a few 30-round magazines for mine, but they're a bit clunky. But I could see using a drum set-up on my StG58 or FAL-O Congo with the bipod extended.

The 30 round magazine interferes with a low profile prone shot. The Beta magazine would be perfect but costs too much for an old retired whitey.
The large size hornet spray can will bring the wonders of chemical warfare right into your hands. The spray is good for about 30 feet.
Lastly, should you spray and flic yer Bic, the stuff burns spectacularly.
